I've only had one and that is all I need. I took my neighbor to the range one day and he was pushing the gun forward every time he fired. It was like he was trying to stab the target with the end of the barrel. I tried to tell him what he was doing and he didn't seem to get it, so I showed him. Second stabbing motion and boom. I had removed the mag but still had one in the chamber. Wasn't a great shot but I did keep it on paper. Now if I unload and check, put the gun down, I will still check again when I pick it up. I know as far as nd goes it was minor but it made an impression on me.
