If you want to stay IWB try a hybrid holster, the Stealthgear is the most comfortable I've found but very expensive ($100). I just ordered an Alien gear and hoping it will do the trick. The backing does distribute the pressure piints more and makes it much more comfortable for me. I'd love to carry appendixe, but no luck with my large lunch muscle.

+1 on the don't worry about printing so much. Just make sure it's a darker shirt (light colors tend to let the dark of the gun bleed through). Nowadays, everyone has a cell phone and whatnot hanging from their belt.

If anyone asks, tell them it's a medical issue, and you have to poop in a bag, and you'd rather not talk about it...they'll leave it alone fast.
