I used to carry a smaller gun most days, such as the LCP. I even tried the Kimber Solo. Recently, I've found that I can carry a Kimber Ultra II 3" .45 in a Comp-tac MTAC holster appendix carry. It has alot of room for adjustment as far as the cant and depth of ride IWB. I have a few shirts that don't conceal that well, but overall, I'm able to hide it well. CorneredCat, as mentioned earlier, is a great resource. You might also check out Packing Pretty's

Good luck and don't give up. It took me a a few gun/holster/belt/position attempts to find the best combination for me.
