While it looks very tactical for a drop leg its very impracticle for going through obstacles climbing things and getting in and out of vehicles. My preference is a belt holster.
I dont like the chest molle holsters that are so popular simply because if your being shot at going prone is your best defense then drawing a weapon. If the firearm is on your chest under you you cant get it without raising up... since its under you its gonna hit the ground hard increasing chances of breakage.
Drop isnt much different in that you cant easily draw it sitting in a vehicle.
