All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A firearm training device, comprising:
a housing body sized and configured for receipt in the magazine compartment of a firearm;
a grip assembly attached to said housing body for removably securing said housing body in the magazine compartment of a firearm;
a catch assembly positioned to engage with the slide of a firearm to effect movement of the slide and to be moved by the slide;
a pin catch connected to the catch assembly and operatively positioned to activate a force mechanism; and
a drive assembly operatively driven by said force mechanism and being operatively attached to said catch assembly to effect movement of said catch assembly.
2. The firearm training device according to claim 1, wherein said force mechanism is compressed gas.
3. The firearm training device according to claim 2, further comprising a valve assembly having a slidable valve rod that is movable from an open position to a closed position such that, when in the open position, the valve rod provides a fluid pathway between the valve assembly and the drive assembly.
4. The firearm training device according to claim 2, wherein said compressed gas is provided from a CO2 cylinder positioned within said housing body.
5. The firearm training device according to claim 4 wherein said drive mechanism further includes a plug positioned adjacent said CO2 cylinder to provide an urging force against said CO2 cylinder.
6. The firearm training device according to claim 1 wherein said drive assembly further comprises a drive rod connected to said catch assembly by a cable.
7. The firearm training device according to claim 4 wherein said drive assembly further comprises a spring positioned with said drive rod within said housing body to offset the force of the spring of a firearm.
8. A firearm training device for a pistol, comprising:
a housing body sized to be received in the magazine compartment of a pistol;
a grip assembly for removably securing said housing body to the magazine of a pistol;
a source of compressed gas positioned within said housing body;
a valve assembly positioned adjacent said body housing and operatively connected through a pressure port to said source of compress gas;
a drive assembly operatively connected to said valve assembly by a drive port in fluid communication with said pressure port; and
a catch assembly operative connected to said drive mechanism, said catch assembly being positioned to contact the slide of a pistol for movement of the slide.
9. The firearm training device according to claim 8 wherein said source of compressed gas is a CO2 cylinder.
10. The firearm training device according to claim 8, wherein said valve assembly is operative connected to said catch assembly to be movable between an open valve and closed valve position by operation of said catch assembly.
11. The firearm training device according to claim 8, wherein said drive assembly further comprises a drive rod operatively connected to said catch assembly by a cable.
12. The firearm training device according to claim 8, wherein said grip assembly further comprises an elastomeric grip and a grip press positioned to apply pressure to said elastomeric grip to laterally expand said grip to secure said grip assembly to the magazine compartment of a pistol.
13. The firearm training device according to claim 8, wherein said catch assembly further comprises a pin catch operatively connected to said valve assembly to effect movement of said valve assembly from a closed to an open position.
14. The firearm training device according to claim 13, wherein said catch assembly further comprises a slide catch which is slidably connected to said pin catch and which is positioned to contact the slide of a firearm to effect movement of a slide of a firearm to simulate the firing protocol of a pistol.
15. A method of using a firearm training device for training with a firearm, comprising:
providing an operable firearm having a frame, a barrel, a firing pin, a slide, a trigger and a magazine compartment formed in the frame of the firearm;
removing the existing magazine from the magazine compartment of the firearm;
inserting into the empty magazine compartment of the firearm a firearm training device structured with all components necessary to produce a simulated firing and recoiling in the firearm, the training device comprising a housing assembly, firing assembly and force mechanism sized to fit within the magazine compartment of the firearm without modification of the firearm;
pulling the trigger of the firearm to activate the force mechanism of the firearm training device;
wherein the drive mechanism of the training device acts upon the existing barrel of the firearm to cause a simulated firing of the firearm and to produce a re-coiling of the firearm.
16. The method accordingly to claim 15 further comprising replacing the existing barrel of the firearm with a substitute barrel structured to spatially accommodate the drive assembly of the firearm training device.
