Referring first to FIG. 1, the pistol includes a main frame including a handle portion 10 and trigger guard 12. Fixedly positioned on the main frame is a pressure chamber 14 having a valve 16 at its forward end and a means 18 for communicating with the interior of a disposable pressure source 20 housed within the handle 10. Slidably mounted barrel 22 and hammer 24 are connected to form a unitary assembly by means of a cocking bar 26. The cocking bar is slotted at 28 in order to permit sliding movement with respect to the means 18 and the bar also includes an opening 30 to receive the sear 32 of a pivotally mounted trigger 34. The barrel-hammer assembly is rearwardly biased by means of a spring 36 positioned between the pressure chamber 14 and a bore 38 in the hammer.

A tubular magazine 40 is also fixedly carried on the main frame and includes a spring 42 to urge the projectiles in the magazine toward the rear of the gun. A wall 44 of the main frame is slanted as shown to direct individual projectiles downwardly of the magazine. The upper surface of the main frame above the rear of the magazine has a hole 45 for reasons which will appear hereinafter.

Rigidly carried on the stem of the valve 16 is a flange 46 engageable by the rear surface of the barrel to effect momentary opening of the valve as well as a sealing member 48 which enters the rear portion of the barrel to provide a seal between the barrel and the pressure source during actual firing.
