If you want OWB, Leather, custom for the pistol, look at DM Bullard's "Bodyguard." I have about 4 of them (including the one I use for my Legion and MK), and really like the 25 degree cant, which I can't (!) find anywhere else.
Look in their "In Stock" section and you'll almost always find a Sig P226 w/Rail listed. It's just plain saddle leather, pancake-style, but very well made, rides high and tight and very comfy.
If it's in stock, you'll have it in a couple days. $85 + S&H, so not bad.
Worth a look...
