Abstract
Abstract A locking mechanism for placement into the ejection port of a gun. The device when placed into the port of the gun is keyoperated to prevent the removal of the device and will not allow the gun to be fired until it is removed therefrom. The device is also of such structure so that it cannot be forced out of the port. The core of the mechanism is also removable by the owner in order to provide quick key changes.
