An actuator system for the trigger return in double-action revolvers includes an actuating rod having a rounded end engaged in a recess in the trigger with a helical coiled return spring biasing the rod by means of a cylindrical shoulder thereon and a rotary abutment member having a bore, which bore serves as a guide for the axially shiftable rod. The system provides an improved double-action operation since it compensates for the increasing reaction of the spring by reducing the lever arm or moment of this reaction on the trigger during its rearward movement. An improvement enables the user to control the "trigger weight" in a single-action operation by the provision of a return spring control bushing which can be adjustably threaded in the rotary abutment member to vary the effective operating length of the spring.
