Lol, perhaps these days, but not in 1973 when I was worked on a house framing crew. There was certainly no “safety” on those nail guns. I got so comfortable with the nail guns that I would swing the gun up by the hose and grab hold of it. One time, as I tried to get hold of the gun, I guess I hit the trigger as I swung up the gun. The gun fired a nail into my upper thigh muscle. I didn’t feel a thing, but when I looked down, I saw the nail sticking out of my leg. I think only about an inch of so of the nail went in. I just reached down and pulled it out. The weird thing was, it never hurt and it never even bled after I pulled it out. I guess it went in and came out very cleanly.
