Well, that's where gun training should come in, if Fat Man comes off his stool, then hopefully his Glock will have its safety on and have an empty chamber.
Of course, this increases the time required between draw and fire, but stops you from shooting yourself in the arse.
That being said, I am rather rusty on the nature of modern pistols, and being a Brit we don't get into that really, we prefer knives...
