ABSTRACT:
Disclosed is an improved integrally recoil-compensated slide action pistol having a frame, a barrel having a bore on a barrel axis, the bore having a caliber diameter, a feed slide connected to the frame for movement parallel to the barrel axis between open and closed positions, the barrel being substantially enclosed between the slide and the frame in the closed position thereof. The improvement provides lateral front enlargement of the barrel and having a front sight mount; and a pair of compensator ports in fluid communication with the bore that exit at upper shoulder surfaces of the enlargement, the slide being formed for lateral exposure of the enlargement in the closed position. The enlargement is formed flush with the slide in the closed position thereof, the feed slide and the enlargement having symmetrical side surfaces on opposite sides thereof, respective side intersections of the shoulder surfaces with the side surfaces extending on the enlargement parallel to the barrel axis, the exhaust passages extending laterally to the shoulder surfaces, exiting upwardly and outwardly, a side portion of each exhaust passage terminating proximate the corresponding side intersection for obscuring the presence of the exhaust passages.
