BACKGROUND

Several jurisdictions across the country restrict the manufacture, sale, or possession of semiautomatic firearms equipped with pistol grips. Some states merely list “pistol grip” as a prohibited feature without further defining the nature or structure of the prohibited pistol grip. In Title 11, section 5471(z), of the California Code of Regulations, the prohibited pistol grip is defined as a pistol grip that protrudes conspicuously beneath the action of the weapon, which means a grip that allows for a pistol style grasp in which the web of the trigger hand (between the thumb and index finger) can be placed beneath or below the top of the exposed portion of the trigger while firing. This definition includes pistol grips on standard and bullpup firearm designs. Thus, it would be beneficial to provide a pistol grip for a semiautomatic firearm that is not prohibited under most regulations.


SUMMARY

According to various example embodiments of the disclosed subject matter as described herein, there is disclosed, illustrated, and claimed a firearm trigger guard insert and grip. Example embodiments of the disclosed firearm trigger guard insert and grip include a removable trigger guard insert, which lowers the top of the exposed portion of the trigger; and a grip, which enables a pistol style grasp where the web of the trigger hand (between the thumb and index finger) can be placed at or above the top of the exposed portion of the trigger while firing the firearm. Example embodiments are described in more detail below.

DETAILED DESCRIPTION

In the following detailed description, reference is made to the accompanying drawings that form a part hereof, and in which are shown, by way of illustration, specific embodiments in which the disclosed subject matter can be practiced. It is understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the disclosed subject matter.


According to various example embodiments of the disclosed subject matter as described herein, there is disclosed, illustrated, and claimed a firearm trigger guard insert and grip. Example embodiments of the disclosed firearm trigger guard insert and grip include a removable trigger guard insert, which lowers the top of the exposed portion of the trigger; and a grip, which enables a pistol style grasp where the web of the trigger hand (between the thumb and index finger) can be placed at or above the top of the exposed portion of the trigger while firing the firearm.



FIG. 1 illustrates an example embodiment of a firearm trigger guard insert 6 and grip 10 installed in a firearm lower receiver 12. FIG. 1 shows the reference plane 5 where the upper and lower receivers of the firearm mate together. FIG. 1 also shows the trigger 8 and the trigger guard 9, which are standard components of the firearm lower receiver 12. As part of the standard configuration of lower receiver 12, an original action line 4 is shown, which corresponds to a boundary below which the trigger 8 is exposed. The action line 4 defines a boundary below which corresponds to the action of the weapon. As explained above, the California Code of Regulations, prohibit a pistol grip that protrudes conspicuously beneath the action of the weapon, which means a grip that allows for a pistol style grasp in which the web of the trigger hand (between the thumb and index finger) can be placed beneath or below the original action line 4 while the weapon is fired.


In the example embodiment shown in FIG. 1, a firearm trigger guard insert 6 is provided to lower the original action line 4 to a new action line 2. The new action line 2 serves to lower the action of the weapon. In the example embodiment, the firearm trigger guard insert 6 can be a formed piece of plastic, composite material, metal, wood, or any other rigid material, which can be removably snapped into place in an upper portion of an area defined by the trigger guard 9. The firearm trigger guard insert 6 includes a void through which the trigger 8 can be inserted. The void includes space for the trigger 8 to be fully pulled backward to discharge the weapon. The trigger guard insert 6 can be formed or manufactured with an upper surface conforming to at least a portion of an area defined by the firearm trigger guard 9. As shown in FIG. 1, the firearm trigger guard insert 6 reduces the exposed portion of the trigger 8, thereby lowering the action of the weapon. When the firearm trigger guard insert 6 is installed as shown in FIG. 1, the trigger guard insert 6 shifts the action line to new action line 2 by covering up a portion of the trigger 8, thereby moving the exposed top of the trigger 8 downward.


When the firearm trigger guard insert 6 is installed and the new action line 2 is thereby created, a horizontal surface 3 of grip 10 can be configured in a collinear position relative to the new action line 2 created by the installed firearm trigger guard insert 6. As a result, grip 10 can provide a surface 3, upon which the web of the trigger hand (between the thumb and index finger) can be placed while the weapon is used. Because the horizontal surface 3 of grip 10 is in a collinear position relative to the new action line 2 created by the installed firearm trigger guard insert 6, the web of the trigger hand will always be in a position at or above the new action line 2. The horizontal surface 3 of grip 10 serves as a physical barrier to maintain the web of the trigger hand in a position at or above the new action line 2. As shown in the example embodiment of FIG. 1, the grip 10 can be configured as a standard grip or a pistol grip in a variety of different styles.



FIG. 2 illustrates an example embodiment of the installed firearm trigger guard insert 6 and grip 10 relative to a new action line 2 of the firearm lower receiver 12. In the example embodiment shown in FIG. 2, the firearm trigger guard insert 6 is installed to lower the original action line 4 to a new action line 2. The new action line 2 serves to lower the action of the weapon. As shown by the dashed line in FIG. 2, the horizontal surface 3 of grip 10 can be configured in a collinear position relative to the new action line 2 created by the installed firearm trigger guard insert 6. As a result, horizontal surface 3 of grip 10 serves as a physical barrier to maintain the web of the trigger hand in a position at or above the new action line 2. FIG. 2 also illustrates a magazine release button 11 of the firearm in an example embodiment.



FIG. 3 illustrates a perspective view of an example embodiment of the installed firearm trigger guard insert 6 and grip 10 installed in a firearm. In the example embodiment shown in FIG. 3, the firearm trigger guard insert 6 is installed to lower the original action line 4 to the new action line 2. The horizontal surface 3 of grip 10 can be configured in a collinear position relative to the new action line 2 created by the installed firearm trigger guard insert 6. As a result, horizontal surface 3 of grip 10 serves as a physical barrier to maintain the web of the trigger hand in a position at or above the new action line 2.



FIG. 4 illustrates an alternative example embodiment showing an integrated firearm trigger guard 14 integrated with shortened insert 401 installed in a firearm lower receiver 12. Also shown is grip 10 installed in the firearm lower receiver 12. In the alternative example embodiment shown, the integrated firearm trigger guard 14 with shortened insert 401 includes a removable trigger guard portion, which can be integrated with a shortened insert 401 as a single insertable/removable component. The shortened insert 401 can be locked into place by attaching the removable trigger guard portion to the firearm lower receiver 12. Once installed, the integrated firearm trigger guard 14 with shortened insert 401 serves to lower the original action line 4 to the new action line 2. The horizontal surface 3 of grip 10 can be configured in a collinear position relative to the new action line 2 created by the installed firearm trigger guard insert 401. As a result, horizontal surface 3 of grip 10 serves as a physical barrier to maintain the web of the trigger hand in a position at or above the new action line 2. The integrated firearm trigger guard 14 with shortened insert 401 shifts the action line downward by covering up a portion of the trigger 8, thereby moving the exposed top of the trigger 8 downward. This alternative example embodiment allows for a bolt release lever to be installed for additional user customization of the weapon. This alternative example embodiment also uses the existing trigger guard mounting holes on the lower receiver 12.



FIG. 5 illustrates an alternative example embodiment of the grip. In the alternative example embodiment shown, the grip 20 can be removably attached to the lower receiver 12 at a reference plane 18. The grip 20 can be removably attached to the lower receiver 12 using a bolt, screw, or other fastener (e.g., a Socket Head Cap Screw, SHCS) inserted co-axially with reference axis 17 through a hole in the grip 20 provided therefor. The bolt, screw, or other fastener can secure the grip 20 to the lower receiver 12. As described above, the grip 20 can include a horizontal surface 19 of grip 20, which can be configured in a collinear position relative to the new action line 2 created by the installed firearm trigger guard insert 6. As a result, horizontal surface 19 of grip 20 serves as a physical barrier to maintain the web of the trigger hand in a position at or above the new action line 2.



FIG. 6 illustrates an exploded view of the alternative example embodiment of the grip 20 with an attachment mechanism 17 (e.g., bolt, screw, or other fastener) for attaching the grip 20 to a firearm lower receiver 12. FIG. 6 shows a typical lower receiver 12 with an integrated (non-removable) trigger guard 601. FIG. 6 illustrates an example of a lower receiver 12 where the trigger opening profile varies. There could be any number of trigger opening profiles. The profile of the trigger guard insert 6 as described herein can be tailored/altered/matched to any number of different types of trigger opening profiles while lowering the action line to ensure functionality consistent with the claims of the various embodiments disclosed and claimed herein.


As shown in FIG. 6, the grip 20 can be removably attached to the lower receiver 12 using a bolt, screw, or other fastener 17 (e.g., a Socket Head Cap Screw, SHCS) inserted co-axially through a hole in the grip 20 provided therefor. The bolt, screw, or other fastener 17 can be used with a lock washer 18 to secure the grip 20 to the lower receiver 12. The lock washer 18 provides tension on the grip 20 assembly when the fastener 17 is tightened, thereby securing all components in place. As described above, grip 20 can include a substantially horizontal surface 19, which can be configured in a collinear position relative to the new action line 2 created by the installed firearm trigger guard insert 6. As a result, horizontal surface 19 of grip 20 serves as a physical barrier to maintain the web of the trigger hand in a position at or above the new action line 2.



FIG. 7 illustrates an exploded view of the alternative example embodiment of the grip 20 with the attachment mechanism 17 (e.g., bolt, screw, or other fastener) for attaching the grip 20 to a firearm lower receiver 12, along with a shortened removably installed firearm trigger guard insert 701. FIG. 7 shows a typical lower receiver 12 with an integrated (non-removable) trigger guard. The shortened removably installed firearm trigger guard insert 701 can be attached to the firearm lower receiver 12 using fasteners 36. The fasteners 36 can be bolts, screws, or other type of mechanical fastener (e.g., a Socket Head Cap Screw, SHCS). The fasteners 36 can also be non-mechanical fasteners, such as glue, snaps, clamps, tongue and groove fittings, or even clamped to the trigger 8 itself. FIG. 7 illustrates an example of a lower receiver 12 where the trigger opening profile varies. There could be any number of trigger opening profiles. The profile of the shortened removably installed firearm trigger guard insert 701 as described herein can be tailored/altered/matched to any number of different types of trigger opening profiles while lowering the action line to ensure functionality consistent with the claims of the various embodiments disclosed and claimed herein.



FIG. 8 illustrates an example embodiment of the grip 10 and a shortened firearm trigger guard insert 701 removably installed in a firearm lower receiver 12, along with a rifle stock 42 (e.g., AR-15 A2 pattern), attached to the firearm lower receiver 12. FIG. 8 shows a typical lower receiver with an integrated (non-removable) trigger guard. The shortened removably installed firearm trigger guard insert 701 can be attached to the firearm lower receiver 12 using fasteners 36. The fasteners 36 can be bolts, screws, or other type of mechanical fastener (e.g., a Socket Head Cap Screw, SHCS). The fasteners 36 can also be non-mechanical fasteners, such as glue, snaps, clamps, tongue and groove fittings, or even clamped to the trigger 8 itself. FIG. 8 illustrates an example of a lower receiver 12 where the trigger opening profile varies. There could be any number of trigger opening profiles. The profile of the shortened removably installed firearm trigger guard insert 701 as described herein can be tailored/altered/matched to any number of different types of trigger opening profiles while lowering the action line to ensure functionality consistent with the claims of the various embodiments disclosed and claimed herein. The example embodiment of FIG. 8 illustrates a rifle stock 42 (e.g., AR-15 A2 pattern) attached to the firearm lower receiver 12 with a stock end plate 41 disposed therebetween. The position of the rifle stock 42 relative to the grip 10 provides sufficient spacing to enable a person to position the web of their trigger hand on the grip 10 while using rifle stock 42. The horizontal surface 3 of grip 10 serves as a physical barrier to maintain the web of the trigger hand in a position at or above the new action line 2.
