I realize this is an older thread, but I figure if I'm reading them others are too. I carry a Para P10-45 which is a double stack gun with a 3" barrell. The wider butt does make concealment more difficult, but the more I carry the more I agree with previous posters that most folks are completely clueless of that there are responsibly armed citizens in their midst and don't notice even if you do print. If you are concerned, a good holster holster helps. I usually carry OWB in a High Noon Holster 'Slide Guard', although now that I've dropped about 50 pounds and have some britches with a little room I can carry IWB (High Noon 'Tail Gunner') more comfortably. I don't always carry a second mag but, depending on where I'm going add that to the belt with the cell phone, Leatherman, and ham radio. I don't carry a BUG, bug have a Bond Arms 'Texas Defender' that would work with a proper holster.
