Been staring at this for 3 minutes trying to figure out how to draw from that.
I've staring at it for 3 minutes trying to figure out how it's attached to his belt, because I don't think it's designed to be carried there(belt clip is showing). Slid the belt through the holster maybe?
It's a Bagmaster holster. It has a belt slide on both sides, and you can move the metal clip from side to side as well. Decent, inexpensive, non-tactical brand of holster. Just not the way he's using it.
