I wear a heavy gunbelt as a regular belt because when I carry concealed, I just tuck the gun inside my waistband at 4 o'clock and call it good. Because of the burly strength and thickness of the gunbelt, this works GREAT with all of my pistols, full size as well as compacts. I carry for several hours this way every day. The heavy gunbelt is really the key element here! Only issue I've had is with my 40C... the mag catch button is so sensitive that it's the one semi-auto pistol I have that when I carry this way... the mag catch button tends to get depressed slightly at times, just enough to drop the mag while the gun is tucked in my waistband. I wish I could find a way to beef up the mag catch spring so it would take a fair bit more than just barely touching it to activate the drop. I have a bunch of holsters for a bunch of great carry guns and whenever I use them, I always go back to IWB carry with gunbelt, but without holster and it just feels and works great for me. I guess I just don't like the extra bulk that holsters add. :roll:
