Yep yep. In one if the Ferguson threads we talked about 21ft rule n home invasions. I always thought I was prepared. .....boy was I wrong.
I can only imagine how fast a mugging in a parking lot would go if your weapon was a taser or wasp spray tucked inside a purse. At 21 feet you better have a gun out and ready or your screwed.
I train at 21 feet and closer :-) If I can stay within a 6'' paper plate or preferably much closer on my groupings I'm ok with that.
