carry it. I have carried a full framed steel Witness in 10mm often, though, and had no problems. While I more often carried the compact steel Witness, I never had much problem. I did have to be picky with the shorts I wore and modify them all to use paracord for a drawstring through an external sliplock thing I got from REI - and it did always leave an indentation all the way around from it, but I never had it slip. In jeans I never had a problem. I always used a Kydex IWB with a sleeveless outer button-up work shirt (unbuttoned, like a thin vest) over it.
I even occasionally carried my suppressed Glock 20 that way - no one ever noticed, but it was weird sitting down with something that went halfway to your knee!
The shoulder rig would probably be better, but, except when I was in the 170's for a few years about two years ago, I could never reach it, as can few fat guys or most women, unless they have an extra arm segment surgically added...
