It is desirable to secure hand guns against unauthorized use, and to this end is provided a locking block (12) for insertion into the breechblock (6) of the gun. The locking block is provided with key operated locking rollers (22), which, upon insertion, are lockable in projecting positions, in which they cooperate with the depressions (8) of the breechblock. By means of balls (28, 32) the locking block (12) is protected against drilling attacks, and the lock may be designed for mechanical or electronic operation. |
