<p>The hand gun breech mechanism briefly locks the moving barrel and breech/block after firing, separating them only when a releasing recess is reached. It secures the breech block in the forward position by means of closing springs and holds the whole system to the butt by a locking device. Below the barrel (3) is a locking roller (6) and the barrel is guided in rails on the breech block (4). Recesses for the roller are formed in barrel, breech block and butt, and the barrel has an auxiliary closing spring. The whole breech system is secured to the butt by a locking device engaging automatically.</p> |
