The "recoiling breach assembly" was a danger, eh? When firing a handgun, something similar can happen where part of the gun comes sliding back and can skin you hand if you hold it wrong. You can't just pick up a gun and start shooting like an idiot. There are safety precautions that you have to know about. In fact I bet a lot of people posting zombie apocalypse threads don't even know where the button to unload the magazine is located.
