Howdy Pards and Pardettes.
New Salem Bob, Pard I like Tru-Ivory from Bar S Grips, I have them on a Colt and a pair of Beretta Laramies. They are not cheap, but the price includes custom fitting, and the grip profile that you want. I have a pair of Rugers with them now to have Tru Ebony grips made for them.
That is all I think I know.
