Does anyone know if these guns have steel grip frames and ejector rod housings? I know they have the earlier XR3 frame. I'm thinking about having either one of those or an Old Model Blackhawk re-finished by Turnbull. If I use an Old Model Blackhawk that I have found it may cost me more as the grips and rod housing may need to be replaced That could run another $200-$300. If I start with a gun that already has those, I obviously save money. All things being equal I would rather have the Old Model with the 4 clicks.re-done. I'm talking about re-bluing and case hardening frame and hammer.
