A while back, I ran across a 4 3/4 Super Blackhawk .44 mag in stainless. A Little scratched up, but decent. Shot it, and wow, really accurate, but this model has the regular Blackhawk grip, which just does not fit my hand. I ordered a Super Blackhawk Dragoon type grip frame from the Ruger NH plant. It is a casting, a little rough, and does have to be fit to the frame of the gun. You will need to remove metal to match the contours of the gun, then polish. I decided to give the whole gun a polish and a set of nice Rosewood grips, and it came out good. Some fine files, a Dremel type tool with a polishing type head along with some 100, 200, 400, and 600 grit emery cloth, and a cotton buffing wheel on a drill press with some fine metal polish will get the job done. Just take your time to match the contours of the gun. The Bisley grip frame should be very similar, except you will need the bisley hammer and trigger as well. Go on line to Ruger and download an exploded view of the innards of the gun - it makes re-assembly a lot easier. Oh yea, don't forget a small brass punch, a clean work surface, and some small trays to place small parts in. A nice weekend project.
