I am a very large guy, I carry all my guns in my pocket with a pocket holster that I ordered on Ebay from the daltech force store. I got the first on in black and liked it so much I order another on for a large gun in black. I have been very happy with this holster. When I sit down I don't even feel the gun. I am about 300 lbs and this has been great for me.
I'm also a big guy (over 3 bills), and I find it really comfortable wearing OWB. I have a snubie in a leather pancake holster on, as others do, a Daltech Super Bio Belt. Even my family doesn't notice I'm carrying.
Dudes, 300 lbs isn't "very large" unless you're under 5' tall.
