ABSTRACT:
A firearm (1) comprises a housing (2), a barrel (3), means defining a chamber (5), and a firing mechanism including a trigger (10). The chamber (5) is defined by a chamber member (4), which is separate from the barrel (3) and is mounted in the housing (2) for reciprocation between a firing position and a loading position transversely to the axis of the barrel. In the firing position, a forward end of the chamber (5) coaxially adjoins and is open to the barrel bore and the rear end of the chamber (5) is closed by a closing wall (7) of the housing (2). In the loading position, both ends of the chamber (5) are exposed on the outside of the housing and spaced from the barrel and the closing wall. A firearm having a structure which is simple, rugged and reliable in operation is provided in that the chamber member (4) constitutes a part of the firing mechanism and the kinetic energy of the chamber member arriving in its firing position is utilized to fire the cartridge contained in the chamber by an action on the primer of said cartridge.
