Cimarron and Taylors both take their standard Model P Uberti Revolvers and send them out to noted gunsmiths for competition action jobs. They, in turn, sell these as their "competition ready" guns. They have various names for these. Most are fitted with after market main springs and refitted with wire springs for bolts and hands. This spring "upgrade" makes the guns very durable.
With most Uberti guns, you're better off buying from a reputable 'smith (Cody, Longhunter, Evil Roy) or picking a gun out in person. The eyetalian gunz can be made to work, but rarely do as they come from the factory. One of the questionable things that the eyetalians do is heat treat after final machining. Things often get warped this way and are left uncorrected by the factory. You really want to deal with a local gunsmith rather than Uberti.
For example, the front and rear holes for the basepin sometimes end up on different axes. This makes it impossible to square the cylinder with the barrel. Best to have a 'smith take care of all this before you take delivery of an eyetalian gun.
