This Oversized Firing Pin Stop from EGW (EGW part no. 10361) is a stainless steel, direct-fit fire control part for the compact 1911 Commander frame, cut for Series 70 pattern .45-caliber pistols. The firing pin stop is the C-shaped plate at the rear of the slide that retains the firing pin and its spring; an oversized (O/S) stop is machined slightly larger than factory spec so a gunsmith can hand-fit it tightly to the slide’s firing pin stop channel.
