When can you be absolutely certain a gun cannot fire?
When the action is open and it is completely empty.
- When the action is open and the gun is empty ✔
- When the safety is on
- When the magazine has been removed
Why: A safety can fail, and a removed magazine can still leave a round in the chamber. Only an open, empty action is certain. That is why you open the action and look whenever you pick up or hand over a gun.
Huh, didn't know that: The NSSF says a dropped gun can fire even with the safety on if the blow is hard enough.
Why did the gun case love open houses? It liked everything out in the open.
