ABSTRACT:
In a trigger mechanism for firearms, in particular of the adjustable type for target-shooting pistols, the actuator of the mechanism is constituted by an elastic element (29) which is pivoted to the hammer (23) in an upward position and is pivoted, in a downward position, to an element (39) which can slide on the body (5) of the firearm; by acting on the sliding element, the elastic element is inclined so as to vary the direction of the actuation force with respect to the lever arm formed by the fulcrum (25) of the hammer with the upper pivot (27) of the elastic element. The safety device disengages the trigger from the operation of the firing mechanism.
