Abstract

In a fire arm of the self loading pistol type having a reciprocating breech block slide (B) with a detachable breech block insert (F) holding a cartridge extractor (M) and a firing pin (S), the insert (F) is held in position in the slide (B) by means of the rear sight (N) of the fire arm. The rear sight is of bifurcated construction, the two limbs locating in respective vertical slots in the sides of the insert (E) and the top in a transverse slot in the slide (B). One limb (N3) of the bifurcation may contain screw means for adjusting the height of the rear sight, such adjusting means thereby being protected against damage and dirt.
