The hand gun has a sight system consisting of a rear sight (9) and a bead (10). There is a cover for the sight system in the form of a guard (5) and a fit-on shoe (4), preferably made of elastic plastic. The shoe can be fitted to the barrel (1) or to a rail (2) below it. The guard should preferably come between the rear sight and the bead.
