A trigger assembly comprises a trigger frame having a body with a cavity therein, a handle connected to the body, a trigger guard on the body defining a space with which a portion of the cavity is in communication, a connection member on the body, a slot member on the body, and abutment surfaces within the cavity. It also comprises a trigger pivotably mounted and movable within the trigger frame and comprising a body portion, a pivot connection means on the body portion connectable to the connection member of the body, a lever extending from the body portion for contact by a user, an engagement portion for engaging a firing mechanism to initiate discharge, and a rod connection means associated with the body portion for connecting the trigger to a rod to initiate re-arming.

Device according to claim 1, wherein said at least one push rod (21) acts upon a cam surface (26) formed on the rear of said at least one balancer (24, 25). 3. Device according to claim 1, wherein said at least one balancer (24, 25), at least one spring guide (22) and at least one spring (23) are integrated in the structure of a fore-end (12) of said break open firearm. 4. Device according to claim 1, wherein said at least one balancer (24, 25) comes out from said iron fore-end (8) through slits of a, length proportional to a degree of rotation of said iron fore-end (8) in relation to said action body (6). 5. Device according to claim 1, wherein said at least one balancer (24, 25) has an optimized profile so as to achieve a perfect balancing or a partial self-closing effect according to an opening angle and a stop function at an end of an opening stroke of said barrel (9). 6. Device according to claim 1, wherein said at least one barrel (9) is equipped with a targeting system. 7. Device according to claim 1, wherein said at least one barrel (9) has a center of gravity in a misaligned position with respect to said hinge pin (7) in order to create an unbalancing torque to cause said least one barrel to fall spontaneously once said open-close top lever (13) is unlocked. 8. Device according to claim 1, wherein said iron fore-end (8) has a shaped end surface placed in rotary engagement with a matching end surface facing said action body (6).
