Dovetail Trigger Shoe Assembly
A traditional 1911 is configured to receive a magazine within a magazine well. As the magazine is inserted into the magazine well, it is guided through a trigger bow. Traditional 1911 trigger bows are swaged with a trigger shoe, thereby forming a trigger shoe assembly. The trigger shoe assembly is then installed on the firearm by inserting the trigger shoe assembly through a back opening of the magazine well and translating the trigger shoe assembly through the magazine well until the trigger shoe extends through a front opening of the magazine well, thereby forming a trigger cavity between the trigger shoe and the magazine well. Although the traditional 1911 assembly process and engagement feature is satisfactory in certain situations, it would be beneficial to have an alternative assembly process and engagement feature.
Adjustment of certain features of a 1911 are also not optimum. For instance, adjusting traditional trigger shoe assemblies often requires removing the assembly from the firearm, which first requires complete disassembly of the firearm. Accordingly, it would be beneficial to have a system for and a method of adjusting a trigger shoe assembly without requiring removal of the trigger shoe assembly from the firearm and/or otherwise not requiring complete disassembly of the firearm.
Like the 1911, the 2311 utilizes a trigger bow that extends around a magazine inserted into a magazine well. Unlike the 1911, the 2311 trigger bow dovetails with the 2311 trigger shoe, thereby providing superior engagement over traditional swaging of the components. The trigger shoe assembly of the 2311 further includes a set screw extending vertically through a top rear portion of the trigger shoe so as to bias a front tab of the trigger bow into full engagement with the trigger shoe. The trigger shoe and trigger bow further include corresponding lips that are configured to interlock when the front tab of the trigger bow is in full engagement with the trigger shoe. In this way, the robust joint of the 2311 trigger shoe assembly provides more assembly and adjustment possibilities than are available for a traditional 1911 trigger shoe assembly.

This ensures that the trigger shoe assembly 300 remains securely in place during firing and handling of the firearm.
In addition to the above features, the trigger shoe assembly 300 incorporates a set screw 330, which plays a crucial role in biasing the trigger bow 320 into full engagement with the trigger shoe 310. The set screw 330 is positioned within a screw cavity 335, allowing for precise adjustment of the trigger shoe assembly. In certain embodiments, the set screw 330 extends vertically through a top rear portion of the trigger shoe 310, making contact with a top portion of the front tab 325 of the trigger bow 320. This contact point allows for the application of controlled pressure, ensuring a consistent and optimal engagement between the trigger shoe 310 and the trigger bow 320.
To facilitate convenient and efficient adjustment of the trigger shoe assembly 300, particularly in terms of the set screw 330, the firearm is designed such that the set screw 330 is accessible from the top of the firearm when the slide 205 is removed. This arrangement enables shooters to make precise adjustments to the trigger shoe assembly without the need for complete disassembly of the firearm. By simply removing the slide 205, the set screw 330 becomes readily accessible, allowing for easy modification of the trigger shoe assembly to suit individual preferences or specific shooting requirements.
It should be noted that various modifications and variations can be implemented in the described trigger shoe assembly. For instance, the shape, size, and materials of the trigger shoe 310 and trigger bow 320 can be adapted to accommodate different firearm models or shooter preferences. Additionally, the specific configuration and dimensions of the rear channel 315, front tab 325, lip 317, notch 327, set screw 330, and screw cavity 335 can be adjusted as needed to achieve optimal performance and ease of adjustment.
The trigger shoe assembly and its components can be fabricated from a variety of materials to meet specific requirements such as strength, durability, weight, and cost considerations. Commonly used materials include steel, aluminum alloys, and various metals known for their structural integrity and resistance to wear. These metal-based materials provide robustness and longevity to withstand the forces exerted during firearm operation. Additionally, polymers or polymer blends are often employed in trigger shoe assemblies, offering benefits such as lightweight construction, cost-effectiveness, and the ability to be molded into intricate shapes for ergonomic design. Carbon fiber, known for its high strength-to-weight ratio, may also be utilized to create lightweight and rigid trigger shoe assemblies, catering to shooters seeking optimal performance and reduced weight. The choice of material for the trigger shoe assembly and its parts ultimately depends on the desired balance of factors such as strength, weight, cost, and design considerations for the specific firearm application.
In some aspects, the techniques described herein relate to a firearm including: a slide assembly; a barrel; a frame; and a trigger shoe assembly including: a trigger shoe having a back portion defining a rear channel; a trigger bow having a front tab configured to be received by the rear channel, wherein the front tab and rear channel define corresponding angled surfaces facilitating seating of the front tab within the rear channel, the rear channel terminating at a lip engaging with a notch of the front tab for full engagement of the trigger shoe with the trigger bow; and a set screw biasing the trigger bow into full engagement with the trigger shoe, wherein the set screw extends vertically through a top rear portion of the trigger shoe and engages a top portion of the front tab of the trigger bow.
In some embodiments, the present invention encompasses a firearm that incorporates techniques facilitating convenient adjustment of the trigger shoe assembly without the need for complete disassembly of the firearm. Specifically, the set screw responsible for biasing the trigger bow into full engagement with the trigger shoe is strategically positioned and accessible from the top of the firearm when the slide is removed. This configuration allows shooters to make precise adjustments to the trigger shoe assembly without the necessity of disassembling the entire firearm. For example, consider a semi-automatic pistol equipped with this feature. When the shooter removes the slide of the pistol, typically accomplished by retracting the slide to its rearmost position and engaging the slide stop lever, the top rear portion of the trigger shoe becomes accessible. At this point, the set screw can be easily reached and adjusted using a suitable tool, such as a screwdriver or Allen wrench. By clockwise or counterclockwise rotation of the set screw, the pressure exerted on the trigger bow can be finely tuned, modifying the trigger shoe assembly's engagement and resulting trigger pull characteristics. This arrangement simplifies the adjustment process for shooters who desire to customize their trigger experience without requiring complete disassembly of the firearm. Instead of disassembling the entire pistol, which can be a time-consuming and complex procedure, accessing the set screw from the top of the firearm streamlines the adjustment process. This feature allows shooters to make quick and precise modifications to the trigger shoe assembly, enabling them to optimize their shooting experience according to personal preferences, competition requirements, or specific shooting scenarios.
In certain embodiments, the present invention pertains to a firearm incorporating techniques wherein the trigger shoe is designed in a dovetail shape. The dovetail shape of the trigger shoe offers distinct advantages in terms of secure installation, adjustable positioning, and compatibility with various firearm models and configurations. For example, consider a semi-automatic pistol that features a dovetail-shaped trigger shoe. The dovetail design enables the trigger shoe to be securely installed into a corresponding dovetail groove or slot in the firearm's frame. The geometry of the dovetail shape provides mechanical interlock and resistance against lateral movement, ensuring that the trigger shoe remains firmly in place during firearm operation. This robust installation method prevents unintended shifting or displacement of the trigger shoe, maintaining consistent trigger performance and reliability. Furthermore, the dovetail shape of the trigger shoe allows for adjustability. By selecting trigger shoes with different dovetail dimensions or by using shims, shooters can fine-tune the positioning of the trigger shoe to achieve their preferred trigger reach and finger placement. This adjustability accommodates shooters with varying hand sizes, grip preferences, and ergonomic needs, enhancing overall comfort and control during shooting. Moreover, the dovetail design of the trigger shoe promotes compatibility across different firearm models. Many firearms utilize a standardized dovetail groove for trigger shoe installation, allowing shooters to interchange trigger shoes between compatible firearms. This versatility enables shooters to personalize their trigger experience or transfer a preferred trigger shoe to different firearms within their collection, without the need for extensive modifications or customization.
In certain embodiments, the present invention encompasses a firearm incorporating techniques wherein the set screw responsible for biasing the trigger bow includes threading and a locking mechanism. This design allows the user to securely fix the desired position of the trigger bow relative to the trigger shoe, providing stability and preventing unintended movement during firearm operation. For example, consider a firearm equipped with this feature. The set screw, threaded to match the corresponding internal threads of the trigger shoe, enables the user to adjust the position of the trigger bow along the rear channel. By turning the set screw clockwise or counterclockwise, the user can control the amount of pressure exerted on the trigger bow, influencing the trigger shoe assembly's engagement and resulting trigger pull characteristics. Furthermore, the set screw incorporates a locking mechanism to ensure that once the desired position of the trigger bow is achieved, it remains securely fixed in place. This locking mechanism can be in the form of a locking nut, a threaded collar, or a specialized locking mechanism integrated into the set screw itself. When engaged, the locking mechanism prevents the set screw from unintentionally loosening due to recoil or other external forces, maintaining the desired position of the trigger bow. The threaded set screw with a locking mechanism provides shooters with a means to customize their trigger pull characteristics and maintain consistency over time. Once the ideal position of the trigger bow is determined, the locking mechanism can be tightened, effectively securing the set screw in place. This feature offers peace of mind to shooters, knowing that their desired trigger configuration will remain fixed and unchanged during shooting sessions or when transporting the firearm.
In certain embodiments, the present invention pertains to a firearm incorporating techniques wherein a spring-loaded detent mechanism is integrated within the trigger shoe assembly. This mechanism enhances the user experience by providing audible and tactile feedback, specifically when the front tab of the trigger bow is fully engaged within the rear channel of the trigger shoe. For example, consider a semi-automatic pistol featuring this spring-loaded detent mechanism. As the front tab of the trigger bow is inserted into the rear channel of the trigger shoe, the detent mechanism is compressed. Once the front tab reaches the fully engaged position, the detent mechanism is released, producing an audible click or snap sound and a tactile sensation that can be felt by the shooter's finger. The audible feedback serves as an indicator that the trigger shoe and trigger bow are securely and properly engaged. It provides confirmation to the shooter that the components are correctly aligned and ready for firing, increasing confidence in the firearm's operation. The tactile feedback further enhances the shooter's experience by providing a physical sensation of engagement. This feedback is particularly useful in situations where visual confirmation of the trigger engagement may be challenging, such as low-light conditions or when the shooter's focus is primarily on the target. The tactile sensation allows the shooter to verify the proper engagement of the trigger shoe and trigger bow without needing to visually inspect the firearm. By incorporating the spring-loaded detent mechanism into the trigger shoe assembly, the firearm provides an additional layer of reassurance and reliability. Shooters can trust that the trigger shoe and trigger bow are fully engaged and ready to deliver consistent and predictable trigger performance.
In various embodiments, the present invention encompasses a firearm incorporating techniques wherein the trigger shoe assembly is designed to be modular and interchangeable. This feature enables shooters to customize the trigger shoe assembly according to their preferences and provides compatibility with different firearm models, enhancing versatility and adaptability. For example, consider a modular rifle platform that allows users to interchange trigger shoe assemblies. The trigger shoe assembly consists of a removable trigger shoe and trigger bow unit that can be easily detached and replaced with another assembly. Each trigger shoe assembly may have distinct characteristics such as shape, size, texture, or trigger pull weight, offering shooters a range of options to suit their specific needs and shooting styles. By having a modular and interchangeable trigger shoe assembly, shooters can select trigger shoe units that optimize ergonomics, improve trigger feel, or meet specific shooting requirements. For instance, a shooter who prefers a wider trigger shoe with a textured surface may swap out the standard trigger shoe assembly for one that matches their preference. Likewise, a shooter participating in precision long-range shooting may choose a trigger shoe assembly with an adjustable trigger pull weight to fine-tune the trigger response. The modular nature of the trigger shoe assembly also allows for compatibility with different firearm models. By ensuring standardized dimensions and attachment methods, shooters can easily transfer their preferred trigger shoe assembly between firearms within the same platform or even across different models, saving time and effort in customization. Moreover, the modularity of the trigger shoe assembly facilitates easy maintenance and replacement. If a trigger shoe assembly becomes worn, damaged, or requires servicing, it can be quickly swapped out with a new assembly, eliminating the need for intricate repairs or complete firearm disassembly.
In certain embodiments, the present invention pertains to a firearm incorporating techniques wherein the trigger shoe is designed with a textured surface or grip enhancements. This feature enhances the shooter's control and comfort during trigger manipulation, resulting in improved overall shooting experience. For example, consider a semi-automatic pistol equipped with a trigger shoe featuring a textured surface. The texture can take the form of stippling, checkering, or other patterns that provide a tactile grip. When the shooter's finger engages the trigger shoe, the textured surface increases friction and grip, allowing for a more secure and controlled trigger pull. This improved grip helps prevent slipping or unintentional movement of the finger during firing, ensuring consistent and precise trigger manipulation.
In certain embodiments, the present invention pertains to a firearm incorporating techniques wherein the rear channel of the trigger shoe includes an integral alignment guide. This feature facilitates quick and accurate assembly of the trigger shoe assembly with the trigger bow, simplifying the process and ensuring proper alignment between the components. For example, consider a rifle equipped with this feature. The rear channel of the trigger shoe is designed with a built-in alignment guide, which includes ridges, grooves, or other protrusions that correspond to matching features on the trigger bow. When assembling the trigger shoe assembly, the alignment guide aids in aligning and positioning the trigger bow correctly within the rear channel. The integral alignment guide ensures that the trigger bow slides smoothly and precisely into place, reducing the likelihood of misalignment or the need for excessive adjustment. This feature saves time and effort during assembly, particularly in scenarios where quick maintenance, field stripping, or component replacement is required.
In some aspects, the techniques described herein relate to a firearm, wherein at least a portion of the trigger shoe assembly is fabricated from a steel alloy, a polymer, or a carbon fiber.

In certain embodiments, the present invention pertains to a firearm incorporating techniques wherein a trigger safety mechanism is integrated within the trigger shoe assembly. This mechanism serves to prevent accidental discharge of the firearm, enhancing safety during handling and operation. For example, consider a semi-automatic pistol featuring this trigger safety mechanism. The mechanism within the trigger shoe assembly is designed to engage a safety feature that blocks the trigger from moving and prevents it from being pulled unless intentionally disengaged. This additional layer of safety helps prevent accidental or unintended discharge of the firearm. The trigger safety mechanism can take various forms, such as a lever, button, or other components that are incorporated within the trigger shoe assembly. To disengage the safety and allow the trigger to be pulled, the shooter must actively and deliberately interact with the mechanism, typically by applying pressure or manipulating the safety feature.
In some aspects, the techniques described herein relate to a firearm, wherein the front tab of the trigger bow includes a reinforced metal insert, increasing strength and wear resistance at the engagement point with the rear channel of the trigger shoe.
In certain embodiments, the present invention encompasses a firearm that incorporates techniques wherein an adjustable trigger pull weight mechanism is integrated into the set screw. This mechanism allows users to customize the trigger pull force according to their preference, providing a personalized shooting experience. For example, consider a handgun equipped with this adjustable trigger pull weight mechanism. The set screw responsible for biasing the trigger bow into engagement with the trigger shoe includes an innovative design that enables precise control over the trigger pull force. By turning the set screw clockwise or counterclockwise, shooters can increase or decrease the tension applied to the trigger bow, thereby adjusting the trigger pull weight. The adjustable trigger pull weight mechanism provides shooters with the ability to tailor the trigger pull to their liking, accommodating individual preferences, shooting styles, and shooting scenarios. Some shooters may prefer a lighter trigger pull weight for enhanced precision shooting, while others may opt for a slightly heavier pull for added safety and control.

Magazine Catch Retainer Plate
Hand pistols taught by U.S. Pat. No. 984,519, or some variation thereof, (each a “1911”) have been in production for over one-hundred years. During that time, the 1911 has developed a loyal following for a variety of reasons. Unfortunately, the magazine capacity of traditional 1911's is somewhat limited. Accordingly, it would be beneficial to have a firearm that is capable of satisfying 1911 loyalists while offering a higher magazine capacity than a traditional 1911.
A traditional 1911 includes a frame having a magazine well that is configured to receive a single stack magazine. As the magazine is inserted into the magazine well, it is guided through a trigger bow. Unfortunately, the width of the magazine well and trigger bow prevents traditional 1911's from receiving a double stack magazine, such as a P320 magazine. Accordingly, it would be beneficial to have a 1911 style firearm that includes a magazine well and a trigger bow that are each wide enough to accept a double stack magazine.
Traditional 1911 trigger bows are swaged with a trigger shoe, thereby forming a trigger shoe assembly. The trigger shoe assembly is then installed on the firearm by inserting the trigger shoe assembly through a back opening of the magazine well and translating the trigger shoe assembly through the magazine well until the trigger shoe extends through a front opening of the magazine well, thereby forming a trigger cavity between the trigger shoe and magazine well. Although the traditional 1911 assembly process is satisfactory in certain situations, it would be beneficial to have an alternative assembly process, such as an installation process that allows for installation of the trigger shoe prior to engaging the trigger shoe with the trigger bow.
Additionally, a traditional 1911 utilizes a magazine catch to selectively retain a magazine within a magazine well and to selectively release the magazine therefrom. When a magazine is installed, an outward force from a laterally-oriented catch spring biases the magazine catch into engagement with the magazine, thereby retaining the magazine. Upon applying a sufficient inward force to the magazine catch, the outward biasing force of the spring is overcome, thereby disengaging the magazine catch from the magazine so that the magazine can be removed. A traditional 1911 magazine catch is configured to receive a proximal end of the catch spring, thereby inhibiting buckling of the spring as the spring is compressed into the magazine catch during operation. A concentric magazine catch lock extends into a distal end of the spring, thereby further inhibiting buckling of the spring. In other words, the 1911 catch spring is entrapped such that buckling of the spring is prevented. When assembled, the magazine catch and the magazine catch lock each extend into a frame of the 1911 from opposed sides of the frame, thereby forming a catch assembly having a nested catch spring. The catch assembly is positioned behind the trigger shoe such that the magazine assembly traverses the trigger cavity. In other words, the 1911 frame defines a lateral catch cavity and a longitudinal trigger cavity that are in communication with each other. Unfortunately, the communication of the catch cavity with the trigger cavity renders a traditional 1911 frame incompatible with certain magazine catches, such as the P320 magazine catch, thereby rendering the traditional 1911 incompatible with associated magazines. Accordingly, it would be beneficial to have a 1911 style firearm that is compatible with a larger variety of magazines, including the P320 magazine.
Like the 1911, the P320 magazine catch is associated with a lateral catch spring. Unlike the 1911, however, the P320 catch spring is not entrapped within a magazine catch. Instead, the P320 magazine catch and associated lateral catch spring are each installed within a lateral catch cavity of an associated frame such that the catch spring is entrapped between the magazine catch and a front surface of the catch cavity. Unfortunately, the communication of the 1911 catch cavity with the 1911 trigger cavity prevents a traditional 1911 from 1911 from sufficiently entrapping a P320 catch spring. Accordingly, it would be beneficial to have a system for and a method of entrapping a P320 catch spring in a 1911 style firearm.
The following embodiments describe a firearm with a magazine catch retainer plate. The plate is novel in that it sits between the trigger shoe and the magazine catch assembly while also functionally engaging with the magazine catch assembly itself. More specifically, the plate sits between in a cavity within the firearm frame between the trigger shoe and the magazine catch assembly. The plate is designed to fit snugly within the cavity, e.g. the plate can be designed to dovetail into the cavity via a recess in the firearm frame. During assembly and disassembly of the firearm, the plate can be inserted into the frame through the empty magazine well or in any suitable opening of the frame during assembly or disassembly. In some embodiments, the body of the plate can include a bottom portion and a top portion. The bottom portion can be rectangular shaped or trapezoidal shaped to fit the cavity within the frame. Furthermore, the bottom face of the bottom portion can itself have a relief configured to dovetail snugly with a part of the frame. The top portion can also be of rectangular or trapezoidal shape and extend perpendicular or at a slight angle from perpendicular from the bottom portion. In some embodiments, the plate can have a dimple, recess, or insert on the top portion which is useful for pushing the plate into place within the frame via a narrow object like a screw, nail, tweezers, screwdriver, armorer's punch, or any suitable tool that is narrow enough to fit the plate within the frame of the firearm during assembly and disassembly. Furthermore, the top portion of the plate can be configured to fit snugly with a recess on the magazine catch assembly. That is, the recess of the magazine catch assembly is designed to fit the top portion.
Once the plate is inserted into the frame, the magazine catch assembly can be inserted into the magazine catch assembly hole in the frame. Once inserted, the magazine catch assembly can operably engage with the magazine catch plate. Specifically, the magazine catch spring can be pushed against the plate by the user, thereby the spring is stopped or caught by the plate. Applying pressure to the spring against the catch plate, the user can engage the magazine release function of the magazine of the magazine catch assembly. That is, when a magazine is installed, the magazine catch assembly engages with the magazine, thereby retaining the magazine. Upon applying a sufficient inward force to the magazine catch, the outward biasing force of the spring is overcome, thereby disengaging the magazine catch from the magazine so that the magazine can be removed.
It is understood that the placement of the magazine catch plate between the trigger shoe and the magazine catch assembly is crucial. This placement allows for the magazine catch assembly to sit far enough away from the magazine well, thereby allowing the magazine well to fit larger magazines such as double stack magazine and P320 magazines. Thus, the plate allows for much greater compatibility with magazines as compared to the 1911 and other 1911-styled firearms.
In some embodiments, the trigger shoe assembly 400 further includes a third engagement feature 407 for securing the first 403 and second 125 engagement features into selective engagement with each other. In some such embodiments, the third engagement feature 407 is accessible from the top of the firearm frame when a slide of the firearm is removed, thereby facilitating assembly of the trigger bow 404 with the trigger shoe 401 while the trigger shoe 401 is installed within the firearm. In some embodiments, the third engagement feature 407 can be a screw, nail, bolt, rivet, or some other mechanical faster or attachment. This third engagement feature 407 can engaged with the trigger bow 404 via a trigger shoe attachment hole 406. The trigger shoe attachment hole 406 can be accessed from the frame when the slide is removed. This allows for alternative assembly process compared to traditional 1911 models: the user can install the trigger shoe to the frame of the firearm 100 without first engaging the trigger shoe 401 with the trigger bow 404. That is, the trigger shoe 401 can be first attached to the frame, then attached to the trigger bow 404.
The firearm further includes a P320-style magazine catch 225 and a magazine catch retainer plate 411 associated therewith. The magazine catch retainer plate 411 is positioned between the trigger shoe 401 and the magazine catch 225, thereby preventing a catch spring (not shown) of the magazine catch 225 from buckling into a trigger cavity 408 positioned behind the trigger shoe 401.
In some embodiments, the firearm includes an adjustment mechanism 410, such as a set screw or the like. In some such embodiments, the adjustment mechanism 410 extends behind the trigger shoe 401 and is configured to engage with a front surface of the magazine catch retainer plate 411, thereby establishing the maximum allowed rearward travel of the trigger shoe 401. The adjustment mechanism 410 can be inserted into a trigger shoe adjustment hole 402. In some such embodiments, the adjustment mechanism 410 is adjustable, thereby changing the maximum allowed rearward travel of the trigger shoe 401. In some embodiments, the adjustment mechanism 410 is normal to the front surface of the magazine catch retainer plate 411 such that engagement of the adjustment mechanism 410 with the magazine catch retainer plate 411 is relatively uniform, thereby reducing wear.
Furthermore, the magazine catch 225 can be configured such that the magazine well 350 is not encroached upon by the magazine catch. Thus, the firearm 100 is compatible with a larger variety of magazines, including a double stacked magazine and a P320 magazine.
The trigger shoe 419 is positioned in front of the plate 413 such that when an attachment member like the adjustment mechanism 410 is placed or threaded through the trigger shoe attachment hole 420, the member touches the plate 413, thus giving the user a physical barrier by which to measure the movement of the trigger shoe 419.
The positioning of the plate 413 between the trigger assembly 418 and the magazine catch 225 is crucial to leaving enough room in the magazine well to accommodate a variety of magazines including double stack magazines and P320 magazines. Indeed, the tapered upper portion of the plate 413 in addition to its proximity to the trigger assembly 418 allows the magazine catch 225 to not encroach on the magazine well. Thus, the novel design and position of the plate 413 allows greater compatibility with various magazines.

Captive Mainspring and Integral Beavertail
A 1911 includes a frame, a hammer pivotally coupled to an upper portion of the frame, a mainspring housing coupled to a lower portion of the frame, and a hammer strut extending between the hammer and the mainspring housing. The mainspring housing houses a mainspring, which provides the driving force for rotating the hammer from a cocked position to a firing position during a firing sequence. A proximal end of the hammer strut is pivotally coupled to the hammer and a distal end of the hammer strut is engaged with a top end of a mainspring. More specifically, the distal end of the hammer strut is engaged with a mainspring cap, and the mainspring cap is engaged with the top end of the mainspring.
Existing 1911 mainspring housings are pinned to the frame. In some embodiments, opposed flanges of the mainspring housing engage with corresponding channels of the frame prior to the mainspring housing being slid up and into position relative to the frame. The mainspring housing is then pinned to the frame, thereby preventing the mainspring housing from sliding out of position. By retaining the position of the mainspring housing relative to the frame, the mainspring's position is also retained. While presumably satisfactory in certain circumstances, it would be beneficial to have an alternative method of securing the mainspring's position. It would further be beneficial to have attachment methods that are more convenient than existing pin configurations for retaining the position of the mainspring.
A 1911 requires the hammer assembly to be installed before the mainspring housing can be installed. In some existing 1911 configurations, a back panel is then installed over the mainspring housing and the internal firing mechanisms. For some 1911 configurations, the back panel includes a beavertail. Other 1911 configurations include a grip safety having a beavertail. In each configuration, the beavertail is separate from the frame. Accordingly, it would be beneficial to have a 1911-style firearm that includes a beavertail that is integral with the frame. It would further be beneficial to have a method of manufacturing a 1911-style firearm in a manner that allows for the beavertail to be integral with the frame.
When moving the 1911 to a cocked configuration, the hammer is rotated to a cocked position, which causes the hammer strut to compress the mainspring. To retain constant reliable engagement of the hammer strut with the mainspring cap, the 1911 is designed such that the mainspring remains compressed, at least slightly, even when the hammer is rotated away from the cocked position, such as when the 1911 is in an un-cocked or firing configuration. In other words, when the 1911 is fully assembled, the mainspring includes some level of preload regardless of the configuration of the firearm. Unfortunately, the mainspring preload can create some issues associated with installing and removing the mainspring housing from the frame. Accordingly, it would be beneficial to have a system for and method of installing and removing the mainspring without requiring the mainspring to be preloaded.
The present invention comprises a highly modified 1911 hand pistol (the “2311”). The 2311 is similar enough to a 1911 to satisfy most loyalists, while resolving certain deficiencies associated with the 1911. Like the 1911, the 2311 utilizes a mainspring and a hammer strut. Unlike the 1911, the 2311 does not rely on existing pin configurations for retaining the position of the mainspring. Some embodiments of the 2311 include a beavertail that is integral with the frame. Furthermore, the present invention includes a method of manufacturing a 2311 in a manner that allows the beavertail to be integral with the frame. In some embodiments, the 2311 facilitates installing and removing the mainspring without requiring the mainspring to be preloaded.

Handgun Slidestop
Hand pistols taught by U.S. Pat. No. 984,519, or some variation thereof, (each a “1911”) have been in production for over one-hundred years. During that time, the 1911 has developed a loyal following for a variety of reasons. Unfortunately, certain features of the 1911 are not optimized. For example, the slide stop on the 1911 is not ambidextrous, i.e. the slide stop can be engaged much more easily by right-handed shooters. Accordingly, it would be beneficial to have a firearm that is capable of satisfying 1911 loyalists while improving upon certain non-optimized features.
Like the 1911, the firearm disclosed in the present embodiments includes a frame, a slide, and a slide stop for locking and releasing the slide during operation of the firearm. Unlike the 1911, the present firearm includes a slide stop is an ambidextrous slide stop that facilitates locking and releasing the slide during left-handed and right-handed operation of the firearm.
The application provides improvements upon the 1911. For example, the ambidextrous slid stop provides improved accessibility for left-handed shooters. The 1911 pistol traditionally features a slide stop/release on the left side of the frame, which can be challenging for left-handed shooters to operate comfortably. By adding an ambidextrous slide stop, left-handed shooters can easily manipulate the slide stop with their dominant hand, enhancing their ability to quickly and effectively engage the slide. As another example, the disclosed slide stop can streamline reloads and malfunction clearance. The ambidextrous slide stop simplifies the process of conducting slide lock reloads. Shooters can use their thumb or index finger of either hand to engage the slide stop, facilitating faster and more efficient reloading. Additionally, in the case of a malfunction, the ability to manipulate the slide stop with either hand allows for easier clearance of the malfunction and faster readiness for subsequent shots. Finally, the ambidextrous slide stop improves the consistency of each shooter in relation to the handgun. With an ambidextrous slide stop, shooters can maintain a consistent grip and shooting stance regardless of hand dominance. This consistency can aid in training and muscle memory development, as shooters can perform reloads and other manipulations using the same technique regardless of which hand they use to engage the slide stop.
Unlike conventional or existing slide stops such as U.S. Pat. No. 9,068,790 B2, the application does not rely on springs to function. Furthermore, this application does not require one side of the slide stop to be removed first before removing the other from the frame of the firearm. Indeed, there are no screws, pins, or other similar attachment means in many but not all of the embodiments. Rather, this application can use only a mating mechanism to removably attach the slide stop to the frame.
The slide stop 210 being configured to move in and out of engagement with the slide 205, thereby locking or releasing the slide, respectively. The slide stop 210 is an ambidextrous slide stop having left and right portions associated with a respective left and right sides of the frame 215. The slide stop 210 can be configured to engage with the slide stop notch 235 thereby stopping the slide 205 from moving.
The second portion 607 can include a lever arm 609 which can be moved by the user. The first portion 602 and the second portion 607 can be interlocked by an interlocking mechanism including a male mating mechanism 606 on the first portion 602 and a female mating mechanism 608 on the second portion 607. The male mating mechanism 606 can be a protrusion or projection from the distal end of the shaft 604 without any recess. The female mating mechanism 608 can also include a protrusion or projection but perpendicular from the lever arm 609 at the distal end of lever arm 609. The male mating mechanism 606 is configured to mate removably with the female mating mechanism 608. The mechanisms 606 and 608 are configured to mate such that first portion 602 and second portion 607 move operably with one another such that a shooter can engage the stopper 605 with the slide stop notch 235 with either hand whether the shooter is left-handed or right-handed. That is, once the portions are connected, any movement of the first portion 602 necessarily results in movement of the second portion 607 and vice versa.
Though not visually depicted in
In some embodiments, the first portion 602 and the second portion 607 of the slide stop are designed in such a way that they can be swapped or exchanged with each other without any modifications or adjustments to the firearm frame 215. That is, the first and second portions of the slide stop could involve a modular design approach. The first and second portions can be manufactured as separate components that are identical in shape, size, and function. They would have compatible attachment mechanisms and mating features, allowing them to be easily removed from the frame 215 and interchanged with one another. For instance, the first portion 602 and the second portion 607 of the slide stop might have corresponding connectors or fasteners that facilitate their attachment to the frame 215. These connectors could be screws, pins, or other mechanisms that secure the slide stop in place. Interchangeability offers benefits such as adaptability to different hand sizes or shooting techniques. Some users may prefer a larger thumb pad on one side or a different lever design, and being able to interchange the portions allows for personalization to suit individual needs. Additionally, interchangeability simplifies maintenance and repairs. If one portion becomes damaged or worn out, it can be replaced independently without replacing the entire slide stop assembly.
In some embodiments, the mating mechanism between the first portion 602 and the second portion 607 of the slide stop can include a locking mechanism configured to prevent accidental disengagement during an operation of the firearm. When the slide stop is in the engaged position, the detent ball would securely engage the notch, creating a positive locking mechanism. This locking mechanism prevents the slide stop from inadvertently disengaging due to recoil, vibration, or other external forces that may be experienced during firearm operation. To disengage the slide stop intentionally, the user would need to apply a specific amount of force or manipulate the slide stop in a deliberate manner to overcome the resistance provided by the locking mechanism. This ensures that the slide stop remains engaged during normal operation but can still be readily released when intended.
In still other embodiments, the slide stop can be combined with other useful elements such as a visual indicator configured to indicate the status of the slide stop's engagement with the slide stop notch 235. That is, the slide stop can include a visual indicator that is specifically designed to provide information about the status of the slide stop's engagement with the slide stop notch 235 on the firearm 600. A nonlimiting example of a visual indicator could be a small window or cutout on the slide stop itself, which allows the user to visually inspect and determine whether the slide stop is engaged or disengaged with the slide stop notch 235. For instance, when the slide stop is in the engaged position, the visual indicator might show a colored dot or line, indicating that the slide stop is securely locking the slide 205 in place. This visual cue gives the user immediate feedback that the slide 205 is properly locked and ready for operation. On the other hand, when the slide stop is disengaged or released, the visual indicator might show an absence of color or a different pattern, signaling that the slide stop is not engaged with the slide stop notch 235. This visual cue serves as a reminder to the user that the slide 205 can freely move and that the firearm 600 may need to be reloaded or attended to.
In still other embodiments, the first portion 602 and the second portion 607 of the slide stop have specific alignment features that facilitate their proper mating or connection with each other via their respective mating mechanisms. A nonlimiting example of alignment features for mating on the first and second portions of the slide stop would involve corresponding recesses and protrusions. These features are designed to align the two portions precisely when they are brought together during assembly. For instance, the first portion 602 of the slide stop might have a recess or groove machined into its surface, while the second portion 607 could have a corresponding protrusion or ridge that fits snugly into the recess. This ensures that when the two portions are joined, they align perfectly, allowing for a secure and stable connection. Alignment features can play a crucial role in ensuring the proper functioning of the slide stop. They prevent misalignment, wobbling, or unintended movement of the slide stop during firearm operation, which could compromise the reliability and safety of the firearm 600. By incorporating alignment features, the first and second portions of the slide stop can be easily and accurately positioned relative to each other, ensuring a precise and consistent engagement and disengagement of the slide stop with the stop notch of the handgun slide. These alignment features simplify the assembly process for the user, enabling them to quickly and accurately join the first and second portions without the need for complex adjustments or excessive force.

In some aspects, reference made to a firearm 200 is meant to include the following elements found in conventional handguns such as without limitation: a frame; slide, barrel; trigger; hammer; firing pin; sight; grip; magazine; trigger guard; safety; slide release; extractor; ejector; recoil spring; magazine release; magazine base plate; disconnector; sear; sear spring; magazine follower; magazine spring; and pin retainers. One or more of these elements can be included in the term “frame,” “firearm,” or both.
It is understood that some or all of the devices or elements thereof can be made or manufactured out of one or more materials. These materials can include without limitation: steel; stainless steel; aluminum; titanium; a zinc alloy; brass; polymer; fiberglass; thermoplastic; polyethylene; polyamide; polycarbonate; and polypropylene. The use of different materials for the first and second portions of the slide stop offers several advantages. By allowing a combination of metal, polymer, and composite materials, the firearm manufacturer can optimize the slide stop's performance and functionality. For example, using a metal material for the first portion 602, such as steel or aluminum, can provide strength and durability to withstand the forces involved in locking and releasing the handgun slide. On the other hand, employing a polymer or composite material for the second portion 607 can contribute to weight reduction, enhancing the overall maneuverability and ergonomics of the firearm. Additionally, the choice of materials for each portion can be tailored to specific requirements, such as corrosion resistance, impact absorption, or friction reduction. This versatility in material selection for the first and second portions of the slide stop 210 enables firearm designers to achieve the desired balance of strength, weight, and performance characteristics, ultimately enhancing the overall user experience and satisfaction.
Although some elements with reference to the firearm have been described, they are not exhaustive. Other elements can be added to make the slide stop more versatile, user friendly, or mechanically sound. For example, the firearm can include an adjustable tension mechanism on the first portion 602 to customize the force required for engaging and disengaging the stop notch. This mechanism allows the user to customize or adjust the amount of force or tension required to engage and disengage the stop notch on the handgun slide. For example, the adjustable tension mechanism could be a small screw or set screw embedded within the first portion 602 of the slide stop. By turning the screw clockwise or counterclockwise, the user can increase or decrease the tension applied to the stop notch. For instance, when the tension is set to a higher level, it would require more force or effort from the user to engage or disengage the slide stop. This can provide added security and prevent accidental engagement or disengagement of the slide stop during firearm operation. Conversely, if the tension is set to a lower level, it would reduce the force required to operate the slide stop. This can be useful for users who prefer a smoother and easier slide stop operation or for individuals who may have limited hand strength.
Debris Channels
A 1911 includes a frame, a hammer pivotally coupled to an upper portion of the frame, a slide slidably coupled to the frame and forming a void therebetween (the “barrel void”), and a barrel positioned at least partially within the barrel void. The barrel is coupled to the frame and operably linked to the slide such that movement of the slide causes the barrel to move as well. In particular, the barrel rocks backward towards a loading position as the slide moves backwards towards a cocking position. After cocking and loading the firearm, the slide and the barrel move simultaneously back to their respective firing positions. Unfortunately, the 1911 is at least somewhat susceptible to debris migrating into internal areas of the firearm, such as the barrel void. Once inside the firearm, the debris can collect in one or more working joints of the firearm (and/or can collect in one or more other areas) in such a way as to cause unnecessary wear or other damage. Accordingly, it would be beneficial to have a 1911-style firearm that includes provisions for mitigating risk associated with debris.
Of particular concern is debris migrating into the barrel of the 1911, such as through the breech of the barrel during a loading operation for the firearm. Accordingly, it would be beneficial to have a 1911-style firearm that includes provisions for directing debris away from the breech of the barrel.
The present invention comprises a modified 1911 hand pistol (the “2311”). The 2311 is similar enough to a 1911 to satisfy most loyalists, while resolving certain deficiencies associated with the 1911. Like the 1911, the 2311 includes a barrel void positioned between a frame and a slide. Both firearms also include a barrel positioned at least partially within the barrel void. Unlike the 1911, an inner surface of the frame of the 2311 defines a relief in communication with the barrel void (or forming part of the barrel void, as the case may be), the relief being configured to capture debris, thereby mitigating risk associated with the debris. Furthermore, some embodiments of the 2311 include provisions for directing debris away from a breech of the barrel.
The debris management elements provide several benefits over conventional handguns. For example, the debris management elements can enhance reliability of the handgun. Debris, such as dirt, dust, or small particles, can disrupt the smooth functioning of the firearm's moving parts. By reducing the risk of debris entering the internal areas, particularly the barrel void, the firearm's reliability and overall performance can be improved. Unwanted debris can cause malfunctions, misfeeds, or other operational issues, leading to potential failures or delays in critical situations. Furthermore, the debris management system can reduce the need to maintain the handgun and in turn improve durability. Debris accumulation in working joints or other areas of the firearm can contribute to increased wear and tear. Over time, this can lead to mechanical problems and a decrease in the firearm's lifespan. By designing the 1911-style firearm with better debris mitigation, the need for frequent cleaning, maintenance, and repairs can be reduced, ensuring long-term durability and minimizing downtime. Furthermore, these elements will improve consistency and accuracy of the handgun in use. Any foreign material present in the barrel or other critical areas of the firearm can affect the accuracy and consistency of the shots. Even small debris particles can disrupt the trajectory of the bullet or affect the timing of the firearm's cycling mechanism. By minimizing debris intrusion, the firearm can maintain its intended precision and consistency, crucial for accurate shooting. Finally, these debris management elements will improve safety and functionality. A clean and well-maintained firearm is essential for safe operation. Debris inside the firearm can potentially interfere with safety mechanisms or cause unintended behavior, posing a safety risk to the shooter and those in proximity. Improving debris mitigation in the 1911-style firearm ensures that it operates as intended, reducing the likelihood of accidental discharges or other safety-related issues. In summary, enhancing the debris mitigating elements of the 1911-style firearm leads to improved reliability, reduced maintenance requirements, increased durability, consistent accuracy, and enhanced safety. These benefits collectively contribute to a more effective and reliable firearm for the user.

Modular Firearm Block
Hand pistols taught by U.S. Pat. No. 984,519, or some variation thereof, (each a “1911”) have been in production for over one-hundred years. During that time, the 1911 has developed a loyal following for a variety of reasons. Unfortunately, the front sight on the 1911 is on the slide, which moves during firing. Thus, aiming is made more difficult. It would be beneficial to provide a firearm with a front sight that could be stationary during firing.
The following description relates to a modular firearm block that is can be removably attached to the frame of a firearm, e.g. the frame of a handgun. The firearm block can be attached to the frame via one or more attachment mechanisms such as a pin and pin connector. Also, the block can be configured to mate with the frame via a dovetail attachment mechanism or some other suitable mating mechanism. In an exemplary situation, the user can assemble the barrel and slide to the frame of the firearm. Then, after pulling back the slide, the user can attach the block to the frame of the gun via the attachment mechanisms. Thus, the block is fully modular.
The modular block offers a stationary sight while the firearm is firing or cycling, thus improving the aim of the user. Furthermore, the pin and pin connectors (as well as the dovetail configuration) make the block easy to assemble and disassemble from the firearm. Thus, the user can much more quickly release the front system and swap out other modular blocks, clean the firearm, or other action that requires partial or complete disassembly.
Additionally, the modular block can act not only as a stationary sight, but also as a muzzle brake. That is, the modular block can reduce recoil and control muzzle rise during firing. It can redirect and manage the gases that are expelled from the barrel when a round is fired, thereby mitigating the effects of recoil on the shooter. Such muzzle braking is particularly useful for competition pistols, where fast follow-up shots and recoil management are crucial for performance. Regardless, the modular block can mitigate recoil in any shooting situation. Furthermore, the modular block can address muzzle rise and flip. Muzzle rise occurs when the front of the handgun rises during firing due to the recoil forces. This can make it challenging to maintain sight alignment and sight picture for follow-up shots. A compensator's design directs the expelled gases in a way that counteracts the upward motion of the muzzle, keeping the firearm more stable during rapid fire and enabling quicker target reacquisition. Although not illustrated in the figures, it is understood that some embodiments of the modular block can include ports specifically designed to manage the escape of gases while firing. Furthermore, the frame of the handgun in the following embodiments is configured to receive multiple different modular blocks. This would be useful in situations where the shooter would like to switch out modular blocks for competitions or for aesthetic purposes.
