Oh, yes, indeed. I had no idea before, how much the support (and comfort) of a proper gun belt gives.
In fact, I own several -- Nexbelt and Kore Essentials. Unfortunately the buckles don't interchange.
I wear one all day every day. My leather OWB holster has belt snaps of the correct size, and my mag pouch has a clip; so they're pretty easy to clip on and off when I go out.
I had no idea either. My duty rig was a kydex inner belt and a hybrid outer belt that was quite stiff. When I went to investigations, I tried using regular belts and they were horrible. I switched to gun belts and it was an amazing difference. I'll never go back, even when I don't carry anymore!
