Wap41,does everything else fit right? The super black hawk is about 1/2 longer but i never heard of ruger making a brass one. May be a after market one.There are after market grip frames made for them. I used to do a lot of custom work on rugers and used the after market ones.Lot of steel frames to replace the aluminum ones on black hawks, round trigger guards on super's, and cut a lot and reshaped to birdsheads.My favorite was putting bisley grip frames on a black hawk along with the bisley hammer.I have a set of composite ivory grips that fit the reg black hawk or ROA that you can have if you want them. They are plain but i do have a pair of ruger medalions that i can put in them too.They have just been in a box of stuff i have under the bed for years now gathering dust.I just looked and i have one side of ivory super black hawk grips, dont know where the other one is, and i have a set of ivory super black hawk grips that have been altered to a very mild birdshead shape, actually just the back bottom corners rounded a little bit.I also have a back site for a ruger single action gather dust in the box.
