Also went the Cross Breed route that Alelks went with (few posts back).
I recently picked up a Cross Breed Holsters Super Tuck IWB holster and its the bee's knee's. Looking at it the bare holster one may say "ick" compared to a Kramer or High Noon holster, but I take functionality over aethstetics anyday. I have tried a few different holsters and this one carries the best for me, its comfortable even when sitting and allows me to wear a t-shirt and not worry about "printing".
This particular holster is for a Springfield XDm 9mm. I ordered the regular horsehide super-tuck, but I ended up cutting it down to match the "combat cut" that one can get from the company. The cut came out great, I can get a really good grip with minimal effort. I was doubtful of the kydex clips at first, but I have done approx. 70 test draws so far and all that comes out is the pistol, not the holster. The kydex comes pre-formed to your specific pistol, but included directions allow you to safely and easily fine tune the molding with a hair dryer. I molded mine a little tighter after doing some jogging with the holster, and retention is exactly were I want it: secure yet smooth on the draw. The areas that I molded were around the ejection port and trigger gaurd. Super easy.
If I were to get another CBH for my 1911, I would not get the combat cut due to the presense of a hammer and larger grip.
The price is right too, worth a look if your in the market for an IWB. Lifetime warranty.
