| 摘要 |
A safety device for a firearm which is adapted to be received in the breech of the firearm and which has a retaining member located in but extending through the body thereof, which retaining member can either be in a condition where it is in contact with the breech and acts to prevent outward movement of the device, to a position where it does not obstruct any such outward movement, whereby the safety device can be readily removed from the breech. Preferably, the two positions of the retaining means are controlled by a key operated lock.
