The Navy Arms M1885 military holster will hold Schofields, Russians, Remingtons, Colts, virtually anything. The Carrico M1885 holsters are well-made, but are extremely tight on my S&W Schofield, which is slightly smaller than the Uberti; they won't accept my Uberti Russian at all. I have two of the Carricos (bought 'em 2nd-hand, unused), and I'm going to try wet-molding one of them to the Schofield.
Edit: Oops! I meant Dixie Gun Works, not Navy Arms. Specifically, look for item #ML1942.
