If they steal it from you easily I question the retention on your holster, I use a simple Uncle Mike's holster with a strap that snaps on the side of the holster, I've had friends try to take it off of me, short of standing right behind me facing the same direction as me it's not something they do without me being made very aware. If someone gets your gun away from you without you knowing or being able to put up any resistance don't even consider carrying.
