Firearm having chamber status indicator and firearm retrofitting method |
摘要 |
A semi-automatic breech locking pistol has a reciprocally movable slide which includes an integral bolt and defines an upwardly and laterally outwardly open ejection port forward of the bolt. A barrel at least partially disposed within the slide has a chamber and a rearwardly extending headspace extension hood and provides a closure for the ejection port in locked breech condition. A chamber status indicator formed by a rearwardly open notch in the headspace extension hood facilitates determination of chamber status by direct visual observation and may also include a forwardly open groove in the bolt which cooperates with the notch in locked breech condition.
