I wanted a 4 5/8" 357 Magnum Blackhawk Bisley but since Ruger doesn't seem to make one, I decided to put one together. I started with a new Blackhawk and then found a used 7 1/2" Bisley 357 at a Bass Pro. I swapped the grip frames, putting the steel Bisley grip on the shorty and the aluminum plow handle on the long barrel for the time being.
Used these tools
Fitted and blended the frames together
Cleaned and degreased the parts with Dawn dishwashing soap and brake cleaner. Applied about 6 or 7 coats of Oxpho-Blue, using #000 steel wool between applications. Gave me more of a really dark grey finish instead of the original blue-black factory look.
The final product. The ears and the sides took most of the work. I used the Power Custom Bisley hammer, a factory Bisley trigger modified according to Power Custom's instructions, modded the pawl to spin free, and refinished the grips with a coat of tung oil.
Later,
Pete
