Paul Sokolovsky's Automaster.45 auto pistol was intended to be free of all external screws, pins, and slide stops. A single pin is used to hold the rear sight, and the safety and magazine release are both actuated through the use of sliding flanges mounted on either side of the trigger. Stainless steel and other alloys are used in the frame, slide, and other metal parts, and the grips are walnut. This is the second and final pre-production Prototype II (ca. 1985). Only about 50 were made.
