Sucks to be wrong, doesn’t it? At least I gave you very specific reasons not to do what you are doing. You can’t even give a reason for carrying behind the back. I guess you saw Magnum PI do it on TV and you thought it looked cool. If you are not smart enough to follow the suggestions of experts, then the choice is yours. BTW, I also don’t know of any CCP instructor who will certify you if you carry behind the back.
The only and single reason small of the back holster are discouraged by “experts” is because on a range line, the muzzle sweeps the other shooters. It’s the same exact reason shoulder holsters are discouraged.
