DETAILED DESCRIPTION

In the following description, numerous specific details are set forth to clearly describe various specific embodiments disclosed herein. One skilled in the art, however, will understand that the presently claimed invention may be practiced without all of the specific details discussed below. In other instances, well known features have not been described so as not to obscure the invention.

Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of “including,” “comprising,” or “having” and variations thereof herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items. Unless limited otherwise, the terms “connected,” “coupled,” and “mounted,” and variations thereof herein are used broadly and encompass direct and indirect connections, couplings, and mountings. In addition, the terms “connected” and “coupled” and variations thereof are not restricted to physical or mechanical connections or couplings.

Referring now to FIGS. 1-4, there is shown a firearm 10 according to some of the embodiment of the present disclosure. FIGS. 1-2 illustrate a complete firearm that includes a frame 20, a barrel 21, and a butt 23, while FIGS. 3-4 illustrate the frame of the firearm in greater detail.

The frame 20 can have a forward end 24 and a rear end 25 opposite the forward end 24. The frame 20 can include an operational magazine well 50 and a secondary magazine well 60. The magazine wells 50, 60 can be adapted to receive and hold a magazine in each magazine well.

The operational magazine well 50 can be operational, while the secondary magazine well 60 can be non-operational. For example, the operational magazine well 50 can have an upper end 52 that is open, allowing a projectile 12 in the operational magazine 54 to be transferred to a firing assembly and fired from the firearm 10. Put another way, the operational magazine can be in communication with a passage within the firearm in which a bolt reciprocates to feed cartridges from the magazine into a well at the breech end of the barrel 21. In contrast, the secondary magazine well 60 can have an upper end 62 that is closed, such that a projectile 12 in the secondary magazine 64 cannot be transferred to a firing assembly and the barrel 21 within the frame 20.

The tact that the upper end of the well 60 may be closed is not necessary to get the operational benefits of the invention, but it does provide a secondary benefit of avoiding a potential entry point for debris or other contamination that may occur in some firearms. For instance, gas-operated firearms are said to “exhaust where they feed” and the soot from the exhaust gas can coat surfaces that are in communication with the bolt passage. While this is not generally a problem for a primary magazine in a gas-operated semiautomatic rifle because the cartridges are consumed as they might be dirtied, a spare magazine and its top exposed cartridge might remain in place for not just many shots, but many magazines, Thus, protecting a reserve magazine from such potential contamination helps to ensure that the exposed top rounds are clean and readily feedable when needed.

The frame 20 can further include a trigger 22 operable to initiate firing of a projectile 12 from the firearm 10. The trigger 22 can be disposed between the operational magazine well 50 and the secondary magazine well 60. For example, the operational magazine well 50 can be disposed forward of the trigger 22 and closer to the forward end 24 of the frame 20 than the secondary magazine well 60. The secondary magazine well 60 can be disposed behind the trigger 22 and closer to the rear end 25 of the frame 20 than the operational magazine well 50.

According to some embodiments presently disclosed, the secondary magazine well 60 can be disposed within the grip 70.

The operational magazine well 50 and the secondary magazine well 60 can have different lengths between their respective upper ends 52, 62 and a bore axis 90 of the barrel 21. In particular embodiments, the upper end 52 of the operational magazine well 50 can be closer to the bore axis 90 of the barrel 21 than the upper end 62 of the secondary magazine well 60.

The operational magazine well 50 can also be at a different general major angle than the secondary magazine well 60. As particularly illustrated in FIG. 4, the operational magazine well 50 can have a general major angle α with respect to the barrel bore axis 90 that is greater than a general major angle β of the secondary magazine well 60 with respect to the barrel bore axis 90. The general major angle is measured at the intersection of the magazine center line 91, 92 as measured between the centerpoint 93 from the an inner cross-sectional profile at a lower end 53, 63 and the centerpoint 95 from an inner cross-sectional profile at the upper end 52,62 to the bore axis 90 of the barrel 21.

Referring now to FIG. 5, which illustrates a bottom view of the frame excluding the magazines, an inner cross-sectional profile 55 of the operational magazine well 50 can be complementary to an inner cross-sectional profile 65 of the secondary magazine well 60, such that a magazine that is being stored in the secondary magazine well 60 can be released and inserted into the operational magazine well 50. This means that a magazine fits in both wells in the same way in essentially all respects. The fit is equally close, but also readily enabling the magazine to be inserted and extracted without undue force. In some instances the magazine is desired to “drop-free” under its own weight even when empty when a latch is released. There may be some differences that do not affect the functional interface between magazine and well, such as extra voids between a flat magazine side panel and a curved grip wall, in order to provide consistent wall thicknesses, moldability, machinability, material conservation, or weight reduction.

The secondary magazine well 60 can have a longer height Hs than the height Ho of the operational magazine well 50. For example, a larger portion of the magazine length can be outside of the magazine well when that magazine is in the operational magazine well versus the secondary magazine well. The height of a magazine well is measured as the distance between the upper end 52, 62 and the lower end 53, 63 of the magazine well. Also, some firearm platforms provide magazines of different lengths and capacities that are compatible with the same firearm, including short magazines for compact pistols, with long magazines being accepted by those pistols, and extended capacity magazines holding 30 rounds also being useable while protruding greatly from a pistol, all with the same upper portion and release latch features at the same locations with respect to the upper end. The wells of the illustrated embodiment may accommodate any of a wide range of compatible magazines and enable different strategies for loading, including larger or smaller magazines in either location, depending where protrusions are more acceptable or disadvantageous.

According to some embodiments presently disclosed, the firearm 10 can have an operational magazine release 58 operable to release an operational magazine 54 from the operational magazine well 50. The operational magazine release 58 can be disposed closer to the forward end 24 of the frame 20 than the trigger 22. The operational magazine release 58 can be adapted to be operable with a user's index or trigger finger of the dominant “firing” hand when griping the firearm in a firing position. The operational magazine release 58 can be actuated by a user applying force in a direction generally transverse to the barrel bore axis 90 and the major vertical plane of the firearm. As particularly illustrated in FIGS. 6 and 8, the operational magazine release 58 can include a two piece construction on opposite sides of the frame that engage with each other through the frame. When a user depresses the magazine release initiation area 57 on either side of the firearm toward the frame 20, a latch 59 is released that holds the magazine within the well. Of particular note, this construction allows either a left-handed or right-handed user to actuate the operational magazine release 58 with the index finger of their predominant hand while gripping the firearm in the firing position.

According to some embodiments presently disclosed, the secondary magazine well can have a secondary magazine release 68 operable to release the secondary magazine 64 from the secondary magazine well 60. The secondary magazine release 68 can be disposed closer to the rear end 25 of the frame 20 than the trigger 22. The secondary magazine release 68 can be adapted to be operable with a user's thumb when griping the firearm in a firing position. According to some embodiments presently disclosed, the secondary magazine release 68 can be disposed on the grip 70. The secondary magazine release 68 can be actuated by a user applying force in a direction generally perpendicular to the bore axis 90 of the barrel 21. For example, as particularly illustrated in FIGS. 7 and 8, the secondary magazine release 68 can include a three-piece construction. When a user depresses the magazine release initiation area 67 inward, toward the frame 20, a latch 69 is released that was holding the magazine 64 within the secondary magazine well 60.

According to some embodiments presently disclosed, both the operational magazine release 58 and the secondary magazine release 68 are operable by the user's index finger and thumb respectively, on the same hand, such as the predominant hand, when griping the firearm in a firing position. The user can thus conveniently release the desired magazine(s) without removing their predominant hand from the firing position. Of particular note, this construction allows either a left-handed or right-handed user to actuate the secondary magazine release 68 with their thumb when griping the firearm in the firing position.

Another aspect of the present disclosure is a method for reloading a firearm. Referring to FIG. 9, an exemplary firearm 10 is illustrated in the fully loaded position, Magazines 54, 64 are disposed in the operational magazine well 50 and the secondary magazine well 60.

As illustrated in FIG. 10, after a user empties the operational magazine 54, the operational magazine release 58 can be actuated with the index finger on the user's predominant hand that is grasping the grip 70. The operational magazine 54 is thereby released from the operational magazine well.

As illustrated in FIG. 11, the user can then actuate the secondary magazine release 68 with their thumb on the same hand as the index finger that just released the operational magazine 54. The secondary magazine 64 is released from the secondary magazine well 60 and can be grasped with the user's secondary hand.

As illustrated in FIG. 12, the user can then insert the secondary magazine 64 into the operational magazine well 50.

In this way, reloading time can be significantly reduced and the user has a convenient storage system within the firearm frame for a secondary magazine. Moreover, the user can withdrawal a third magazine (not shown) and insert it into the secondary magazine well at a desired time. Another particular advantage of certain embodiments of the present disclosure is the interchangeability of the secondary magazine in the secondary magazine well with a secondary firearm, such as a handgun. A user could release the secondary magazine from the secondary magazine well and insert the magazine into a secondary firearm.

According to some embodiments presently disclosed, the secondary magazine well 60 can have a secondary magazine release 168 (shown in FIGS. 13 and 14) operable to release the secondary magazine 64 from the secondary magazine well 60. The secondary magazine release 168 can be disposed closer to the rear end 25 of the frame 20 than the trigger 22. The secondary magazine release 168 can be adapted to be operable with a user's thumb when griping the firearm in a firing position. According to some embodiments presently disclosed, the secondary magazine release 168 can be disposed on the grip 70. The secondary magazine release 168 can be actuated by a user applying force in a direction generally perpendicular to the bore axis 90 of the barrel 21. For example, as particularly illustrated in FIGS. 13a and 14, the secondary magazine release 168 can include a four-piece construction. When a user depresses the magazine release initiation area 167 inward, toward the frame 20, a latch 169 is released that was holding the magazine 64 within the secondary magazine well 60.

According to some embodiments presently disclosed, both the operational magazine release 58 and the secondary magazine release 168 are operable by the user's index finger and thumb respectively, on the same hand, such as the predominant hand, when griping the firearm in a firing position. The user can thus conveniently release the desired magazine(s) without removing their predominant hand from the firing position.

The magazine release initiation area 167 is coupled with the latch 169 using, for example, a fastener 170 (shown in FIG. 14). A spring 172 is positioned to return the magazine release initiation area 167 to its resting position after the magazine is released.

According to some embodiments presently disclosed, the secondary magazine well 60 can have a secondary magazine release 268 (shown in FIGS. 15a-b and 16a-i) operable to release the secondary magazine 64 from the secondary magazine well 60. The secondary magazine release 268 can be disposed closer to the rear end 25 of the frame 20 than the trigger 22. The secondary magazine release 168 can be adapted to be operable with a user's thumb when griping the firearm in a firing position. According to some embodiments presently disclosed, the secondary magazine release 268 can be disposed on the grip 70. The secondary magazine release 268 can be actuated by a user applying force in a direction generally perpendicular to the bore axis 90 of the barrel 21.

According to some embodiments presently disclosed, both the operational magazine release 58 and the secondary magazine release 168 are operable by the user's index finger and thumb respectively, on the same hand, such as the predominant hand, when griping the firearm in a firing position. The user can thus conveniently release the desired magazine(s) without removing their predominant hand from the firing position. Of particular note, this construction allows either a left-handed or right-handed user to actuate the secondary magazine release 268 with their thumb when griping the firearm in the firing position.

Referring to FIGS. 15a-b and 16a-i, according to some embodiments presently disclosed, the secondary magazine release 268 comprises a retaining pin 340 (shown in FIGS. 17a-j) configured to extend through the secondary magazine well 60. The retaining pin 340 comprises a front portion 342 and a rear portion 344.

According to some embodiments presently disclosed, the retaining pin 340 comprises a notched section 360 to clear the magazine.
