I would advise you to dress around the gun a bit more. I always wear a belt. Right now I am wearing a Kramer Leather double thick horsehide belt. It's not always as adjustable as I'd like it to be, but it looks nice when I'm dressed for work. I can carry before and after work, not during, but I digress. I have been looking at getting a Wilderness Tactical Instructor's belt
to solve the adjustability problem. I've heard good things about them from anyone that owns one. With that and some shorts with belt loops you'll be good to go. I'm 6' 250lbs and I usually wear an inside the waistband holster with either a Glock 23 or 1911-A1. Both of those holsters are Kramer
holsters. They are built very well and are molded specifically for each weapon.
