ABSTRACT:
A pistol (10) has a combination action spring guide and slide buffer (58). The spring guide and buffer has a plastic head segment (64) and an integral plastic guide rod (66). The head segment has two enlarged diameter portions (68, 70) separated by a recess into which a metal plate (76) is positioned. The metal plate prevents deformation and deterioration of the head segment which acts as a cushion for the pistol slide (20).
