Been carrying a full sized Walther PPQ 9mm for over 3 years now in a Comp-Tac MTAC holster at 3:00 365 days a year. It's there from morning to bed regardless of activity and I forget it's there most of the time. I usually wear jeans but dress pants or short as well and a simple t-shirt will work just as well as a tucked dress shirt or sweater. I've never changed the way I dress nor do I want different holsters for my dress or activity.
