Every year at our Friends of NRA banquet, we have a custom cowboy gun donated. This year the Cajun Cowboy Gun of the Year will include this part in the Ruger revolver. This part is direct from the Ruger factory with a letter of authentication. I'm just going to include one view of the part to see if anyone can guess what the final product will be. Oh, this part is a 1 of 1 kind of thing from Ruger. As the revolver's custom work progresses, I'll post more pictures.
