If it’s too low, if it’s bouncing, you might be doing it wrong. I haven’t experienced any bouncing or discomfort when wearing it in *front* of and slightly above the boys, with the grip of the small, light gun just below the waistband. When it’s lower, or the gun is longer and heavier, it can bounce and pinch.
Riding a horse while wearing one with a 3913 is not a good idea. So I hear.
