when i took friends along and trained them to shoot. they only got one bullet. my one freind who was a good shot, could never shoot more than one in the mag. all giddy from the shooting, he would wave the gun around after.
I shot my first hand gun, a Glock 17, at a range under supervision. Never waved it around. Of course I had completed two years in the Army but had never fired a hand gun.
I think you raise a good point about first time shooters getting “giddy” immediately following shooting off a few rounds. I always stand right up against them ready to grab the gun if, in their excitement, they don’t keep it pointed down range at all times. I tell them in advance of shooting that no matter what keep the gun pointed DOWNRANGE! Even if you think it is empty, keep it pointed DOWNRANGE! Even when you have the safety on, keep it pointed DOWNRANGE!
Then, as I said, not trusting inexperienced shooters I stand right next to them ready to grab the gun and often do.
