I have been a black powder and SAA shooter for over 30 years. With black powder I started out with a Uberti and when I could afford it, I upgraded to the 2nd Generation and Signature Series Colts. My Uberti was/is a great all around entry level gun. Good shooter. My son has it now. Cimarron gets their cowboy guns from Uberti and they are supposed to be the top of the Uberti line.
I have two Cimarron cartridge revolvers that are very good guns ~ however, it was a painful and expensive road to get there.
My first Cimarron was a Lightning 38. Right out of the box, it needed a replacement firing pin. It was not long enough to give a good strike on the primers. They offered to fix it, but considering the postage and turn around time, I had a local gunsmith fabricate one and was back in business in two days. This gun has never given any further problems and is a good shooter.
Next, I bought a Cimarron Bisley. The cylinder on this gun had been so aggressively buffed in the final finish at the factory that it would not even lock up. Cylinder was replaced. Next springs began to fail. I eventually wound up having to replace all the springs. Up next, was the safety hammer assembly. It gave problems until I replaced it with a new one "old style," from VTI. It took a complete rebuild to get the bugs out of this gun. Considering the cost, postage, and time involved, I would have been money ahead to have bought a USFA and had a top quality gun to begin with.
I'm not saying I would not buy another Cimarron depending on what they have to offer. You can always tweak out the glitches. I do not feel their quality warrants a premium price.
