I've seen some "hybrid" holsters that look interesting. Ones that can be front pocket or snap on the square and it goes back pocket. How are the guns designed to be carried in the back pocket? Would it be for palm out draw or palm in? I would think it would be easier to grab the grip between the jeans and the grip as opposed to in between the leather and grip.

I believe the most common use of these back-pocket holster designs involves palm-in draw. This is one of the right-hand back-pocket holsters wich R. J. Hedley made for me. When using it, I carry it as often in the front pocket as I do in the back.
