More than 90% who respond will say "yes", and I don't doubt them. But in my experience it's the other way around in the general population....90% of those who can, don't.
I like it when I'm standing around with people who are discussing in great detail....maybe even arguing about....what gun, caliber, capacity, holster, sights, reloading technique, blah, blah, blah is BEST.
Then I ask, "So, who's got a gun?" and the silence is deafening.
I've done that a couple of times and they look at me like I'm nuts
