For my "always" gun, I'm into deep concealment. Every day, I carry at least one pistol in my right rear pocket in a pocket holster. It looks like a wallet from the outside and I've never been "made" carring a firearm there during the last 19 years or so.
Rear pocket carry may not be the most ideal place to carry a primary firearm, but it is a great place to park a BUG, or a place to carry when dress, weather, or circumstance makes other forms of carry unpractical.
