I just purchased a Ruger Single Seven .327 Federal Magnum 7 shot single action revolver. It is the birdhead frame. I'm not crazy about the grips and am thinking of replacing them. My question is do these Single Seven revolvers use the same grips as a New Vaquero? Or do they interchange with some other revolver with a birdhead frame? Also I'd like any good sources for grips or other accessories for this gun.
