I’ve said it before, I’ll say it again: removing your gun from concealment quickly, efficiently and safely is more important than marksmanship. That’s because many if not most defensive gun uses end without a shot fired. The bad guy or guys see an armed self-defender’s gun and decides not to attack. There are dozens of carry systems – gun + holster – that enable easy access to a firearm. This isn’t the carry system you’re looking for. Not just because the odds of pulling that coin thing off you gun’s grip during a full adrenalin dump are small, especially under a cover garment (not shown). while moving, but also because . . .
manipulating a loaded gun behind your back is an invitation to a Darwin award. I reckon you’d be better off going for Mexican carry: just jam the gun in between your pants and your underwear. I’m an outside-the-waistband guy who carries a Wilson Combat Commander-sized 1911 because it’s the only full-size gun thin enough to disappear between my T-shirt and polo shirt. Can’t wait for open carry. Can wait for this thing. Forever.
