Does anyone know where you can purchase grips for a Cimarron Model 'P' revolver that look like the grips John Wayne used in his movie?

Access the Cimarron site, click on "accessories", click on "grips". Cimarron offers "Tru-Ivory" grips in several stages of "aging", installed and fitted at $200. Possibly less if they will just sell you the grips and you do the fitting.

If that's a bit stiff, try Hogue Grips. They offer just the grips or fitted grips. These may not be "aged" enough for you and you may have to "age" them yourself by soaking them in some form of coloring solution.

Can also access www.gunfighter.com for more sources.
Understand that with the possible exception of Ruger, all other grips for single-actions come slightly oversized and are fitted unless that is not an issue. Best wishes!

You can also get them from Brownell's, all three levels of "aging."
