Sig P238 in front pocket of dress slacks. In the same pocket, I carry my small, leather business card holder on the "outside" of the gun, so the only thing that prints is the little rectangular card holder.
Several guys in the office know I carry (including management), recently two of them asked whether I was carrying that day. I told them to look at me, and guess whether I was indeed carrying. One said "Yes", the other said "No". To the guy who said "Yes", I challenged him and said, "OK, where's the gun?" He was sitting 3 steps away, while I stood in the door frame of his office. He guessed my left pocket, which had keys and a small pocket knife. I pulled them out and told him sorry, you're wrong. He said, "Ok, where's the gun? I know you have it." I pulled the gun out of my right pocket. It had been "covered" with the business card holder. They were both stunned, couldn't believe I had a gun in that pocket...even though they were looking for it!
