I have two Cimarron Model Ps, 7-1/2" bbls., in 44 Special. I fitted them with simulated one-piece ivory grips and I love them. Very nice shooters. I changed the trigger/bolt spring, and the only non-coil spring left is the mainspring. I have had good results talking with Cimarron when I ordered some spare screws/parts in the past.
I bought two with the idea of getting into SASS, but eye problems killed that, so now I am going to sell one Cimarron and one Ruger Vaquero 44. Already sold the Marlin.
