US 6,234,059 B1 · Pistol including a removable structural unit

Abstract

A pistol includes a cross-sectionally U-shaped frame which has first and second opposite side walls, a formed-on grip, a formed-on trigger guard, a first through bore provided in the first side wall and a second through bore provided in the second side wall in alignment with the first through bore. A structural unit is removably accommodated in the frame above the trigger guard and includes bilateral guide rails and a through aperture aligned with the first and second through bores. The structural unit is received in the frame with a form fit for preventing longitudinal displacements of the structural unit relative to the frame. A removable pin passes through the first and second through bores and the through aperture in the structural unit for removably securing the structural unit to the frame. A slide is received in the frame for forward and rearward reciprocating motions relative to the frame. The rails of the structural unit cooperate with the slide for guiding the slide during its reciprocating motions. A pistol barrel is displaceably received in the slide, and a barrel guiding arrangement guides the barrel in the slide. A closing spring is received in the frame underneath the barrel for urging the slide in a forward direction.
