Finally got my CHL a couple of weeks ago. I carry IWB at the 12 or 1 o'clock position, I carry a Glock 45, I noticed with basic t-shirts I would occasionally print if I were to lean forward then stand straight up. the shirt would get stuck on the grip. I went out and bought a size up in t-shirts and got a couple of button-down shirts that provided more concealment. any tips on clothing for carrying during the summer time? I think button-down shirts are the way to go.
