A gas-powered pistol has a frame with a forward- ly opening barrel passage that extends through much of the length of a barrel portion of the frame wherein a recipro- cally movable barrel is housed. Side-by-side magazine and gas supply passages extend from the barrel passage through a grip portion of the frame for receiving therein a re- loadable magazine and a replaceable pressurized gas cylin- der. The frame is formed from metal that is die-cast about a pre-machined metal insert located at the juncture of the barrel and gas supply passages. The insert pro- vides an inlet into which a seal piercing assembly is threaded for receiving pressurized gas from the gas cylin- der, and an outlet into which a valve assembly is threaded that slidably supports the breech end of the barrel. The barrel carries a hammer mass that is engaged by a trigger- mounted sear for moving the barrel forwardly in opposition to the action of a firing spring when the trigger is pull- ed. The hammer mass carries a depending projection that cooperates with a transversely slidable safety to selec- tively block movement of the barrel by the trigger. When the sear disengages the hammer mass of the forwardly-moved barrel, the trigger and sear are returned to their normal positions by a return spring, and the barrel is moved rapidly rearwardly by the firing spring to operate the valve assembly to duct a burst of pressurized gas into the barrel to fire from the barrel a BB pellet that was fed from the magazine through a bottom opening of the barrel before the barrel was released to move rapidly rearwardly.
