A training firearm that provides a realistic recoil effect. The firearm, preferably a pistol, may be an actual firearm retrofitted with a self-contained “blow back” assembly. Usually, the pistol will include a laser device that emits a laser beam readable by a target system. The laser replaces live rounds, and the blow back assembly causes return of the slide to cycle in a manner similar to that caused by live ammunition in an unmodified weapon. The blow back assembly is driven by a disposable cartridge of compressed gas self-contained in the handle of the pistol. A valve integrated with the firing pin releases a burst of gas when the firing pin is impacted by the hammer. The gas pushes back the slide and recocks the hammer for the next “round.” This system provides law enforcement and military personnel a realistic tool to develop recoil management and target re-acquisition skills.

1. A training firearm comprising:a receiver; a barrel supported on the receiver; a slide slidably mounted for bidirectional forward and rearward movement relative to the receiver; a firing pin behind the barrel, the firing pin mounted or movement between a retracted position and a firing position; a firing assembly comprising: a driver movable between a cocked position and the firing position, wherein in the firing position the driver is adapted to impact the firing pin propulsively, and wherein in the cocked position the driver is held in biased condition in preparation for release; and a trigger adapted to release the driver; wherein the slide is adapted to recock the driver when the slide moves bidirectionally; and a blow back assembly interposed between the barrel and the firing pin, the blow back assembly comprising: a tube defining an external pressure chamber, a housing defining an internal pressure chamber, the housing movably received in the tube, the housing having a valve opening fluidly connecting the internal pressure chamber with the external pressure chamber; a closure member movable in the housing between an open position in which the valve opening is open and a closed position in which the valve opening is closed, wherein the closure member is adapted to move in response to advancement of the firing pin; a compartment inside the firearm adapted to contain a compressed gas cartridge; and a conduit adapted to fluidly connect the internal pressure chamber to a th compressed gas cartridge in the compartment; wherein one of the tube and the housing is fixed relative to one of the receiver and the slide, and wherein the other one of the tube and the housing is fixed relative to the other one of the receiver and the slide; whereby, when the compressed gas cartridge is installed in the compartment, activation of the trigger causes the slide to move bidirectionally recocking the firearm. 2. The training firearm of claim 1 wherein the firearm is a pistols.3. The training firearm of claim 2 wherein the driver is a hammer.4. The training firearm of claim 3 her comprising a laser assembly adapted to emit a laser trigger when the trigger is activated.5. The training firearm of claim 4 wherein the tube is fixed to the slide and has a closed rear end with a firing pin passage therethrough, wherein the firing pin has a forward end and is adapted to move reciprocally in the firing pin passage, wherein the closure member comprises a rod movable between a forward position and a rearward position, the rod having a rear end extendable through the valve opening in the housing and an enlarged portion adapted to obstruct the valve opening when the rod is in its rearward position, and wherein the firing pin is sized and positioned so that a forward movement causes the forward end to impact the rear end of the rod to push the rod forwardly to move the enlarged portion away from the valve opening.6.
