So far as I've heard, Cimarron recalled all the Schofields made by Armi San Marco (ASM), though I suppose you could find one floating around somewhere. They'd make an excellent paper weight or wall hanger, but I wouldn't shoot one unless somebody that really knew what they were doing had done major surgery on the locking surfaces. Even then, I wouldn' trust them.
So far as the Uberti Schofields and the Smith & Wesson 2000's are concerned, the general consensus is that they don't do well with black powder, lacking the gas ring relief that the originals had. OTOH, they are pretty good pieces. The S&W has a shorter frame to prevent rechambering to .45 LC. The Uberti follows the frame length of the original, with the cylinder lengthened and the rear of the barrel shortened accordingly to take the longer round. The top strap is also beefed up slightly. They are okay for SAAMI-standard .45 LC pressures.
