Small arm firing mechanism

Abstract

The invention pertains to a firing mechanism for a small arm, particularly a rifle, with a trigger (2) that can be pivoted about a trigger axis (12), with a trigger rod (4) that is displaceably arranged within a housing (1) and serves for respectively retaining and releasing a prestressed firing pin (6), and with an articulated lever (3) that is arranged within the housing (1) such that it can be pivoted about a pivot axis (20) and is connected in an articulated fashion to the trigger rod (4), with said articulated lever being connected to the trigger (2) via the trigger rod (4). The resistance of the trigger can be easily changed without requiring significant constructive modifications if the articulated lever (3) that is connected in an articulated fashion to the trigger rod (4) has an upwardly protruding catch (22) that engages into a lower latching groove (19) on the trigger (2) in a cocked position of the firing mechanism, with the latching groove (19) being provided with an oblique stopping face (33) for a front edge (34) of the catch (22).
