ABSTRACT:
A semi-automatic pistol includes a polymeric frame, a barrel secured to the frame medially of its front end and rear end. A slide is slidable relative to the frame without direct engagement therewith. A retainer and guide member is removably secured adjacent a rear portion of the frame and includes a pair of outwardly extending guides. Each of the guides slidably fits within one of a pair of opposing inwardly facing longitudinal grooves. Each of the grooves is disposed along opposed inner surface portions of the slide for retaining and guiding the slide in generally parallel spaced relation to the frame. The pistol includes a second retainer and guide means adjacent the front end and includes, at least in part, a generally circular aperture in a depending front wall of the slide and wherein the muzzle end of the barrel extends through the aperture. The aperture has a predetermined chamfer to enable the slide to disassembled from the pistol after the first retainer has been disconnected from the frame. The chamfer thereby enables the freed, rear end portion of the slide to be pivoted upwardly to a substantial angle generally related to the chamfer whereby the slide may be removed from the barrel and thus disassembled from the pistol.
