Abstract
A slide for a semi-automatic pistol is provided where the pistol has a frame, a slide mounted on the frame, a barrel mounted between the slide and the frame, and a magazine for feeding cartridges into the chamber of the barrel. The slide includes a front portion for receiving the barrel where the front portion has a breech face end, a block having an elongate passage for receiving a firing pin mechanism, and a cam surface extending from a lower surface of the block adjacent to the breech face end which functions as a feed ramp for feeding cartridges from the magazine to the chamber. The cam surface is a truncated hemispherical protuberance having a flat surface where the flat surface extends at an angle from the breech face. Positive contact between the breech face and the topmost cartridge is ensured during forward movement of the slide.
