Abstract

A strike plate unit that mounts to an automatic pistol to prevent the barrel and the slide of the pistol from being pushed rearwardly out of battery. The strike plate unit mounts to the accessory rail under the barrel of the pistol, and includes a secondary accessory rail that enables lights and other accessories to be attached under the strike plate unit while the latter is mounted to the pistol. The rearward face of the strike plate is positioned forwardly of the muzzle end of the barrel, to create a gap through which gasses escape in upward and outward directions to create a muzzle brake effect. The forward face of the plate is provided with heavy, sharply-pointed checkering that enhances its effectiveness as a striking weapon/tool.

Claims

1. A strike plate unit for being mounted to a pistol having a slide and a barrel having a muzzle end, and an accessory rail located below said slide and barrel, said accessory rail having a locking notch formed therein, said strike plate unit comprising:

a base portion having a mounting channel on an upper side thereof for receiving said accessory rail of said pistol in mounting engagement therewith so as to position said base portion generally beneath said barrel of said pistol;

a plate portion that extends from said base portion so as to be positioned generally in front of said muzzle end of said barrel when said base portion is in said mounting engagement with said accessory rail of said pistol, so that said plate portion will prevent said barrel of said pistol from being pushed rearwardly out of battery; and

means for detachably locking said base portion in said mounting engagement with said accessory rail of said pistol, comprising;

a transverse bore formed through said mounting channel of said base portion so as to align with said locking notch in said accessory rail of said pistol when said base portion is in said mounting engagement therewith; and

a pin member for being passed through said transverse bore so as to cooperate with said locking notch in said accessory rail to lock said base portion of said strike plate unit in said mounting engagement with said accessory rail.

2. The strike plate unit of claim 1, wherein said plate portion comprises:

a plate member for extending over said muzzle end of said pistol in a direction generally perpendicular to said barrel of said pistol when said base portion of said strike plate unit is in said mounting engagement with said accessory rail.

3. The strike plate unit of claim 2, wherein said plate member comprises:

a generally rectangular plate member configured to extend over substantially an entire forward end of both said barrel and said slide of said pistol when said base portion is in said mounting engagement with said accessory rail.

4. The strike plate unit of claim 2, wherein said plate portion comprises:

a rearward face that extends upwardly from said base portion so as to be positioned a spaced distance forward of said muzzle end of said barrel when said base portion is in mounting engagement with said accessory rail of said pistol, so as to form a gap through which gasses escape in upward and outward directions upon firing of said pistol and thereby create a compensating force that counters muzzle rise due to recoil of said pistol.

5. The strike plate unit of claim 4, wherein said gap has a spacing of about 1/32 inch.

6. The strike plate unit of claim 1, wherein said accessory rail of said pistol is formed of a polymeric material and has a predetermined width, and wherein said mounting channel in said base portion has a width sized slightly smaller than said width of said accessory rail of said pistol, so that said channel will cooperate with said polymeric material of said accessory rail to form a sliding interference engagement for stabilizing said strike plate unit on said pistol.

7. The strike plate unit of claim 6, wherein said width of said mounting channel is sized smaller than said width of said accessory rail by an amount in the range from about one thousandth of an inch to about three thousandths of an inch.

8. The strike plate unit of claim 1, wherein said plate portion comprises:

a forward face having large, pointed checkering that forms a plurality of spaced, sharply-pointed tips.

9. The strike plate unit of claim 8, wherein said sharply-pointed tips of said checkering lie substantially in a common plane, so that said forward face of said plate portion is substantially free of elongate, individual protrusions.

10. A strike plate unit for being mounted to a pistol having a slide and a barrel having a muzzle end, and an accessory rail located below said slide and barrel, said accessory rail having a locking notch formed therein, said strike plate unit comprising:

a base portion having a mounting channel formed in an upper side thereof for receiving said accessory rail of said pistol in sliding engagement therewith, so as to position said base portion generally beneath said slide and barrel of said pistol;

a transverse bore formed through said mounting channel of said base portion for aligning with said locking notch in said accessory rail when said base portion is in a predetermined mounting position thereon;

a pin member for being passed through said transverse bore so as to cooperate with said locking notch to lock said base portion in said predetermined mounting position on said accessory rail;

a plate portion that extends upwardly from said base portion so as to be positioned generally in front of said muzzle end of said pistol when said base portion is locked in said predetermined mounting position on said accessory rail, so as to prevent said barrel of said pistol from being pushed rearwardly out of battery, said plate portion being arranged to extend generally perpendicular to said barrel of said pistol and comprising;

a forward face having large, pointed checkering that forms a plurality of spaced, sharply-pointed tips; and

a rearward face configured to be positioned a spaced distance forward of said muzzle end of said barrel when said base portion is locked in said predetermined mounting position on said accessory rail of said pistol, so as to form a gap of about 1/32 inch through which gasses escape in upward and outward directions upon firing of said pistol and thereby create a compensating force that counters muzzle rise due to recoil of said pistol; and

a secondary accessory rail formed on a bottom side of said base portion for attachment of lights and other accessories thereto.

11. A strike plate unit that is mountable to a pistol having a slide and barrel having a muzzle end, and an accessory rail located below said slide and barrel, said accessory rail being formed of a polymeric material and having a predetermined width and locking notch formed therein, said strike plate unit comprising:

a base portion having a mounting channel on an upper side thereof for receiving said accessory rail of said pistol in mounting engagement therewith so as to position said base portion generally beneath said barrel of said pistol, said mounting channel in said base portion having a width sized slightly smaller than said predetermined width of said accessory rail of said pistol, so that said channel will cooperate with said polymeric material of said accessory rail to form a sliding interference engagement for stabilizing said strike plate unit on said pistol; and

a plate portion that extends from said base portion so as to be positioned generally in front of a muzzle end of said pistol when said base portion is in said mounting engagement with said accessory rail of said pistol, so that said plate portion will prevent said barrel of said pistol from being pushed rearwardly out of battery.

12. The strike plate unit of claim 11, wherein said width of said mounting channel is sized smaller than said predetermined width of said accessory rail by an amount in the range from about one thousandth of an inch to about three thousandths of an inch.

13. A strike plate unit that is mountable to a pistol having a slide and a barrel having a muzzle, and an accessory rail located below said barrel and slide, said accessory rail having a locking notch formed therein, said strike plate unit comprising:

a base portion having a mounting channel on an upper side of thereof for receiving said accessory rail of said pistol in mounting engagement therewith so as to position said base portion generally beneath said barrel of said pistol; and
