I had a Cimarron (ASM) Schofield, bought on claims that it was better than the Navy/Uberti. Wrong. A friend got one at the same time. Actually we had three between us to get two that would shoot at all. Those two did not shoot well. I understand they went clear back to Italy with no resolution. Cimarron gave us our money back. I spent mine on a Model P. The fiasco nearly broke Cimarron.
If you just must, insist on an extensive testfire before you pay.
