This point is made with every 1500 and I still don't understand it. The situations aren't the same at all. Where else do you have thousands of people handling guns at the same time, too often pointing them at others because there really isn't a safe direction? It seems that about every second 1500 has a ND even with the no live carry rule because some people think that the rule really doesn't apply to them. I'd hate to think how many NDs they would have if everyone was carrying live. When we carry loaded guns outside the 1500, we aren't continuously handling them. In fact they only leave your holster in case of emergency, at the range or to put away at night.
SO, What exactly is your point. I carry loaded into every place that I go even gun shops. My pistol never leaves the safety of my holster. So where does my ND come from?
