A sear mechanism for firearms comprises a sear box (12), at which a trigger (15) is mounted, a hammer (16) upon which acts an elastic thrust element (33) and equipped with a mounting tooth (40) for the engagement with a fixed sear tooth (41) integral with the sear box (12), a breechblock carrier (13) carrying a firing pin (14), as well as a sear device (17, 17') to give the hammer (16), when controlled by the trigger (15), motion between a cocking position (A) in engagement with the sear tooth (41) and a striking position (B) against the firing pin (14), made up of an initial translation step of a pin (31, 31') of the hammer in a slot (32) of the sear box (12) and a subsequent rotary step under the action of the elastic thrust element (33).
