Locked Breech
Definition
A mechanically engaged breech arrangement that remains locked during the initial firing phase before the design’s opening sequence. Short-recoil systems are common handgun examples. It is distinct from hammer or striker ignition and does not guarantee deeper or more useful case marks.
A locked breech uses mechanical engagement during the initial pressure phase before its designed opening sequence. Different products implement this differently. The label does not guarantee deeper or better breech-face impressions than a blowback design.
