Abstract

A handle (20) for rapidly firing a semi-automatic firearm (22) having a trigger (24). The handle (20) includes a grip portion (52) defining a channel (54). A block (60) that is connected to the firearm (22) is slidably disposed in the channel (54) for allowing longitudinal movement of the firearm (22) relative to the handle (20). The handle (20) also includes a trigger guard (66) disposed on one side of the trigger (24) and extending longitudinally forward of the trigger (24) by a predetermined distance (D) to an open end. The trigger guard (66) presents a finger rest (70) for placing a trigger finger (74) on the trigger guard (66). The trigger guard (66) restricts access to the trigger (24) until the firearm (22) is moved longitudinally forward by the predetermined distance (D) relative to the handle (20). The handle (20) also includes a lock (44) having an open position for allowing longitudinal movement of the firearm (22) relative to the handle (20) and a locked position for restricting longitudinal movement of the firearm (22) relative to the handle (20).

Claims

1. A method of firing a semi-automatic firearm (22) having a trigger (24) comprising the steps of:

supporting the firearm (22) in a forward pointing direction in a handle (20, 120), manually moving the firearm (22) forwardly relative to the handle (20, 120) by a predetermined distance (D), and

restricting access to the trigger (24) until the firearm (22) moves forward relative to the handle (20, 120) by at least the predetermined distance (D).

2. The method as set forth in claim 1 wherein said step of manually moving the firearm (22) includes pushing the firearm (22) forward with human muscle effort while holding the handle (20, 120) generally stationary.

3. The method as set forth in claim 2 wherein said step of restricting access includes covering one side of the trigger (24) with a guard open at the predetermined distance (D) and further including the steps of placing a finger (74) over the open guard and activating the trigger (24) with the finger (74) in response to the firearm (22) moving the predetermined distance (D) relative to the handle (20, 120).

4. The method as set forth in claim 3 further including the step of propelling the firearm (22) away from the trigger (24) with the recoil from the discharge of a bullet in the firearm (22) to move the trigger (24) away from the finger (74) and resetting the trigger (24) in response to the trigger (24) moving a predetermined distance (D) relative to the handle (20, 120) away from the finger (74).

5. The method as set forth in claim 4 wherein said step of pushing the firearm (22) forward with human muscle effort includes temporarily decreasing the effort substantially simultaneously with said propelling step and then increasing the effort following said step of activating the trigger (24).

6. A semi-automatic firearm (22) comprising:

a firearm (22) including a trigger (24),

a handle (20, 120) having a grip portion (52, 150), said grip portion (52, 152) defining a channel (54, 154),

a block (60) for rigidly attaching to said firearm (22),

said block (60) being slidably disposed in said channel (54, 154) for guiding longitudinal movement of the firearm (22) relative to said handle (20, 120), and

a trigger guard (66, 166) extending from said grip portion (52, 152) for disposition on one side of said trigger (24) of said firearm (22) and extending longitudinally forward for stabilizing a stationary object to intermittently collide with said trigger (24) in response to said firearm (22) being moved longitudinally forward by a predetermined distance (D) relative to said handle (20, 120).

7. The firearm (22) as set forth in claim 6 wherein said trigger guard (66, 166) presents a finger rest (70, 170) for holding a finger (74) in a generally stationary position.

8. The firearm (22) as set forth in claim 6 wherein said channel (54, 154) presents a pair of opposing grooves (58, 158) and said block (60) presents a pair of outwardly extending ridges (62) for sliding along said grooves (58, 158).

9. The firearm (22) as set forth in claim 6 further including a lock (44) movable between a first position for allowing longitudinal movement of said firearm (22) relative to said handle (20, 120) and a second position for preventing movement of said firearm (22) relative to said handle (20, 120).

10. The firearm (22) as set forth in claim 9 wherein said handle (20) further defines a bore (42) and said lock (44) comprises a cam (46) and a pin (48) extending perpendicularly away from said cam (46) and into said bore (42) wherein said pin (48) engages a detent (51) in said firearm (22) when said lock (44) is in said locked position and wherein said pin (48) is spaced from said firearm (22) when said lock (44) is in said open position.

11. The firearm (22) as set forth in claim 6 further including a stock portion (26) defining a buffer cavity (28) having a generally tubular shape for slidably receiving a buffer tube (30) of said firearm (22).

12. The firearm (22) as set forth in claim 11 wherein one end of said stock portion (26) presents a butt end (32) for abutting the shoulder of an operator when said firearm (22) is in a firing position.

13. The firearm (22) as set forth in claim 12 wherein said stock portion (26) further defines a vertical rib (34) extending vertically downwardly from said buffer cavity (28) and longitudinally along said stock portion (26) for structurally supporting said stock portion (26).

14. The firearm (22) as set forth in claim 13 further including a horizontal rib (38) extending along said vertical rib (34) for providing additional structural support to said stock portion (26).

15. The firearm (22) as set forth in claim 14 wherein said horizontal rib (38) defines a recessed portion (40).

16. The firearm (22) as set forth in claim 15 wherein said stock portion (26) further defines a bore (42) extending vertically from said recessed portion (40) to said buffer cavity (28).

17. The firearm (22) as set forth in claim 16 further including a lock (44) disposed in said bore (42) of said stock portion (26) and being movable between an open position for allowing longitudinal movement of said firearm (22) relative to said stock portion (26) and a locked portion for preventing movement of said firearm (22) relative to said stock portion (26).

18. The firearm (22) as set forth in claim 17 wherein said lock (44) comprises a cam (46) and a pin (48) extending perpendicularly away from said cam (46) into said bore (42) and a spring (50) for biasing said cam (46) against said horizontal rib (38) and wherein said open position of said lock (44) is with said cam (46) extending parallel to said horizontal rib (38) and covering said recessed portion (40) to vertically space said pin (48) from said buffer tube (30) of said firearm (22) and wherein said locked position of said lock (44) is with said cam (46) being nestled into said recessed portion (40) of said horizontal rib (38) to engage said pin (48) with a detent (51) in said buffer tube (30) of said firearm (22).

19. The firearm (22) as set forth in claim 11 wherein said grip portion (52) is connected to said stock portion (26) and extends downwardly therefrom.

20. A handle (20, 120) for a semi-automatic firearm (22) comprising:

a grip portion (52, 152), said grip portion (52, 152) defining a channel (54, 154) having an open front and a closed back (56),
