Abstract
A handgun frame assembly includes a frame member composed of polymer material. A metallic, one-piece, front structural member has a transverse connector encased in the front end portion of the floor of the frame member and right and left rail segments extending laterally inward from the interior surfaces of right and left side walls of the frame member, respectively. A metallic, one-piece, rear structural member has a transverse connector encased in the rear end portion of the floor of the frame member and right and left rail segments extending laterally outward from the exterior surfaces of the right and left side walls, respectively. A slide is supported on the rail segments of the front and rear structural members for reciprocal sliding movement between battery and retired positions.
Claims24
A handgun, comprising:
- a frame assembly including
- a frame member composed of polymer material having front and rear end portions and right and left longitudinally extending side walls connected by a floor, each of the side walls having interior and exterior surfaces,
- a metallic, one-piece, front structural member having right and left rail segments integrally connected by a transverse connector, at least a portion of the transverse connector being encased in the front end portion of the floor of the frame member and at least a portion of each of the right and left rail segments extending laterally inward from the interior surfaces of the right and left side walls, respectively,
- a metallic, one-piece, rear structural member having right and left rail segments integrally connected by a transverse connector, at least a portion of the transverse connector being encased in the rear end portion of the floor of the frame member and at least a portion of each of the right and left rail segments extending laterally outward from the exterior surfaces of the right and left side walls, respectively;
- and
- a slide having front and rear end segments, the front end segment having an outer surface defining a front pair of oppositely disposed, longitudinally extending grooves, the rear end segment having right and left skirts having oppositely disposed interior surfaces, the interior surfaces of the right and left skirts defining a rear pair of oppositely disposed, longitudinally extending grooves;
- wherein the right and left rail segments of the front structural member are slidingly received in the front pair of grooves and the right and left rail segments of the rear structural member are slidingly received in the rear pair of grooves.
