Almost all of my Rugers have had either a Dragoon or Hunter grip frame installed....the XR3-RED just doesn't work with my hands! Since you want stainless, I'd suggest a Hunter grip frame.
Custom grips are another option. I like Eagle Grips Gunfighter model, especially in water buffalo horn. Caryc and Private Schultz makes some nice ones, as does Klamath River Wood Works and numerous others. Stag-grips.com in Buffalo WY makes elk stag...got 3 pair on Bisleys and 2 pair of Dragoons.
You're 100% right about the custom touches. You made it YOURS and a unique creation.
