OP, I treated your thread as if it were a poll, then went through to see the results you had gathered. 144 posts, about 30 'yes' to displaying to humans, many/most not from the holsters, and few shots fired. NO references to speed of the draw from a holster, few references to caliber of the firearm choice.
My initial reaction is that this confirms my bias, that folks on forums are not gunmen and can't really justify carrying. Not with those anecdotes on a percentage basis. I had a CCW while living in San Diego and gave it up: I wasn't willing to be THAT guy in the liquor store who had to defend the clerk, myself, and everyone else in the shop and out on the sidewalk. And was never sorry about that choice.
Some of you will know my name as I'm The Holstorian and holster designer/maker of extensive experience. I'm also Ayoob trained and have a lot of respect for Mas. He has made a good living as a gun scribe (I gave him his first break when he asked for an interview of my boss then, who was John Bianchi, in the '70s). That being said I can't carry where I live and I don't wish I could. Because I'm mighty glad the other guy can't carry, here, either.
Why would I pay any attention to this anyway, when I live overseas after 50 years in USA? Because carry guns for citizens spend virtually every second of their existence IN the holster, RARELY ever drawn in anger, and the brand of holster they swear by has NO relevance to the course of a conflict. Or the result of one.
We holster makers are a dime a dozen, I've seen 'em come and go and most of 'em are dead already. Buy any brand you want, there's no good reason to wait eons just to claim you've waited X years for your Sparks or whatever. So you can win your next gunfight. Which you are not going to be in. According to the replies to this thread.
Oh, yeah, count me as a 'NEVER' have drawn my carry pistol against a human. But I've been a gunnie since 1963 . . ..
