I have one of those wallet thingies for my P3AT. I don't carry it bcasue my pants are already saggy in the rear so when I have it in my back pocket it feels like I could loose them at any moment. lol.. I have too much overhang out front so I uasally carry on the belt with a small holster with the shirt out. it stays pretty well hidden. Heck I can damn near hide a full size auto that way..
