I'm one of those people. My carry guns are my glock and my LCP, neither of which has a safety (which to me is a good thing). My holster of choice is a shoulder holster, when I'm wearing a jacket, and I'm just not comfortable sweeping everyone around me with one in the chamber. Watch the video again, I don't think the old man lost any time by having to rack the slide, he did it as he was turning around.
