So were at my dad's friend's house and I was shooting my M&P. Well, my dad decided he wanted to give it a go, so i put 5 rounds in it and gave it to him with the chamber empty. Went over the basics (keep your finger off the trigger unless you are going to shoot, treat it as its loaded even if its dry, etc) So he goes out, cocks it, and fires it four times............. So I guess he thought he fired five. He turns around and rests the gun at his side............ with his finger on the god damn trigger. I yell to him to take his finger off the damn trigger. He pulls a with his finger still on the fucking trigger. Instead of telling him to shoot the last round, I let him figure it out. I told him to turn back around and rack the slide. Even after that, he still argued that what he was doing was ok. Needless to say, he will never handle any firearm around me unless he takes a god damn safety class.
