ABSTRACT:
A semi-automatic firearm having a slide axially movable with respect to a frame between a forward battery position where the firearm is discharged, and a full recoil position where the spent cartridge is extracted and a new cartridge is subsequently loading. Either a pair of oppositely wound, concentric springs or a flat helical spring extends between the slide and the frame to form a recoil mechanism which resiliently biases the slide toward battery. The slide partially surrounds a barrel which is pivotally secured to the frame toward its rear end through a link. The slide contacts the barrel at a point diametrically spaced from the link when the slide is in battery thereby resiliently biasing the barrel in a forward direction which imparts a rotational moment to the barrel about the pivot axis of the link. The rotational moment forces the front end of the barrel downwardly against two distinct support areas on the slide. Consequently the barrel is supported by three fixed points which define a stable mounting plane for the barrel. Alternative embodiments of the firearm include a rearwardly extending sight secured to the forward end of the barrel, and a shock absorbing cap receiving the forward end of the recoil spring.
