I like the choice of what to do with my carry gun being mine and mine alone, so concealing it always makes sense to me. Maybe I just want to be a good witness while two motherfuckers kill each other in a Wal-Mart parking lot, I'm not a cop. The only time I open carry is when I'm more worried about animals than people.
Notice how you NEVER see some dude open carrying and are like "that dude clearly knows what's up..." It's always 360lbs of chewed bubble gum with his gut hanging out of a Gruntstyle shirt, diabetic tube socks, velcro shoes, and the aforementioned Uncle Mikes holster. It's probably an XD or a Taurus, or a $400 1911 with Punisher grips, and the biggest fight of his life has the inevitable heart attack he's taking 30 pills a day to stave off.
I'm actually fine with this, he buys the rest of us time since they'll shoot him first. Also, his gun probably doesn't have a round in the chamber so it buys us more time while the methhead that disarmed him works through that problem.
Thanks for coming to my TED Talk.
