A locking system for a firearm, having a rigidly locked breech which can be unlocked by means of a control part driven by gas pressure and has perforations for accommodating locking bodies, which are supported such that they can move radially, in the form of balls or ring segments which, when the breech is locked, engage on locking surfaces which are fixed to the barrel and are formed by sections of a circumferential groove, and are supported on the control part, and are released by the displaced control part when the breech is unlocked, which control part is designed in the form of a piston and is supported inside the breech. <IMAGE>
