ABSTRACT:
A fully gas operated pistol includes a frame unit, a barrel unit, a bolt carrier unit slidably supported on the frame unit and a spring which urges the bolt carrier unit into a forward, bolting position. A path links the breech end of the barrel with a rearward pointing cavity near the muzzle end of the barrel. The cavity is adapted to accommodate a piston of the bolt carrier unit. Gases expanding upon the firing of a bullet expand under pressure into the piston accommodating cavity, thus causing the bolt carrier unit to retract.
