You can purchase just a nickled or SS Thunderer or SS Thunderball (Pietta version) from Cimarron, with or without the Bar-S Tru-ivory grips. If you order with those grips it will take some extra time because the gripframe is sent to Bar-S for the grips to be fitted. You can also buy the gun with wood grips and have other grips fit to the gun yourself (the Bar-S grips are very nice but pricey). The Pietta version has slightly smaller grips than the Uberti version. Also the Pietta version is polished stainless, looks more like nickle. The Doc rig is nickled, not stainless. The Uberti SS Thunderer will be satin SS, not polished. Hope that helps.
