Obviously not.
I don't know and maybe it's just me, but if nail guns have a propensity to fire nails both unpredictably and haphazardly, I guess I'd just take the extra time and hammer it the old fashioned way.
I may smash the hell out of my thumb, but I guarantee I'm not going to drive a nail 1 1/4 inches INTO MY BRAIN!
I just can't imagine not knowing this happened. Maybe if I was on some serious drugs or drunk....I don't know. I mean, when my wisdom teeth came in, I thought my head was going to explode and almost died of shock when the dentist wouldn't see me over the weekend. I spent two days holed up in a dark corner popping pain relievers and contemplating what household item to use to best knock the sons-of-bitches out of my mouth on my own.
