The invention relates to a safety device for a handgun, whereby a component (3) is penetrated by a striking pin (15) which can be moved in relation to said component (3) in order to fire a cartridge. According to the invention, said handgun, preferably an semi-automatic pistol, is improved in that the component (3) comprises at least one push-button (37) which can be externally accessed and pressed and acts upon a switching body (33, 35) which can be rotated about the longitudinal axis of the striking pin (15) for the gradual rotation of the latter; the switching body (33, 35) comprises a noncircular borehole which is penetrated by the striking pin (15); and the striking pin (15) comprises at least one radial projection or at least one radial projecting part (27) which prevents the striking pin from rotating, the outer contour of said projecting part together with the outer contour of the striking pin (15) being complementary to the noncircular borehole in such a way that said part (27) can only fit into the noncircular borehole when the switching body (33, 35) is in a defined rotational position.
L'invention concerne un dispositif de sécurité pour arme à feu de poing pourvue d'un élément (3) qui contient un percuteur (15) mobile relativement à cet élément (3) pour tirer des cartouches. Cette arme à feu de poing, de préférence un pistolet mitrailleur, est perfectionné en ce que ledit élément (3) comporte au moins un bouton-pressoir (37) accessible et pouvant être poussé de l'extérieur, ce bouton-pressoir agissant sur un élément de commande (33, 35) pour le faire pivoter graduellement autour de l'axe longitudinal du percuteur (15). Cet élément de commande (33, 35) comprend un alésage ovalisé, dans lequel se trouve le percuteur (15) pourvu d'au moins un épaulement radial ou d'au moins une partie en saillie radiale (27) qui ne tourne pas. Le profil extérieur de cette partie s'inscrit dans l'alésage ovalisé en complément du contour du percuteur (15), de sorte qu'elle (27) ne peut pénétrer dans l'alésage ovalisé que lorsque l'élément de commande (33, 35) se trouve dans une position de pivotement précise.
