An interchangeable trigger assembly for firearms, particularly for over/under shotguns, which can be applied within a break action of a gun, by insertion in a lower opening of the break action; the assembly includes two detachable portions: a firing unit and a trigger unit, the firing unit including firing members; the trigger unit including at least one trigger which acts on actuation members of the firing members.

A trigger assembly includes a trigger shoe configured to disengage a sear to release a firing mechanism in response to force applied by a user. The trigger assembly further includes a blocking mechanism configured to selectively prevent the release of the firing mechanism in response to a control signal.

A firearm which provides recoil reduction using the kinetic energy of the hammer to cancel a portion of the bolt's recoil after a round has been fired. After the bolt starts to move rearward in response to the detonation, the hammer's forward kinetic energy is transferred onto the bolt by striking it at the moment the bolt starts to travel rearward or after the bolt has started its rearward motion.
