Amazing. You HAVE to carry it loaded, cocked and locked? What happened to carrying with an empty chamber, hammer down. The Israelis seem to do well that way. Shoot her hand, then I am going to have to get rid of my IWB holster because if the safety fails, I will shoot myself in the leg.
Let's keep an open mind. The positive, whether it is staged or not, is that it is showing open carry in a large store. (By the way, I was in The Big Box store at 0130, and there was only the stockers there. I guess, a Lady wouldn't shop at night.)
Remember there are more ways than one to carry a firearm. If she isn't comfortable cocked and locked, then that should be HER priority, not someone who maybe uses a weapon full time or not.
Oh while I am thinking of it, I usually train up to 200 staff members per year with firearms, and some years more.
