I have several Kramer horsehide belt scabbards for various guns, and they are my favorite OWB holsters. They are very stiff and sturdy to hold the gun firmly in place, and they hold up very well over time.
The photo below shows my Sig P229 in a Kramer belt scabbard that was made for a H&K USP 40c. I don't really carry the Sig and prefer the USP for carry, but as an experiment I tried the Sig in the holster. It was a perfect fit, as the guns have the same general dimensions except for the square trigger guard on the USP (as you can see in the holster molding).
As Gideon pointed out, Kramer does "mold in" the shape of a belt in the belt loops of their belt scabbard holsters. All 4 of mine are that way. But I don't believe that it compromises the closeness of the fit, and feel that Kramer does this for a good reason. If they didn't do this, I think the stiff horsehide would require excessive bending of the belt in order to fit through the loops, and the fit would be worse.
Here is my Kimber Pro CDP in a Kramer belt scabbard, showing more clearly what Gideon is talking about with the "oval" belt loops. But this holster fits very well, and is close to my body.
