Get a Grip!

Im sure you could find a GOOD gunsmith in your area with references who can make you set for a reasonable price and just may take the job on to broaden their horizons. Bring pics of the Cuda too, they may give you a discount if you show the finished version on here. Everyone likes more business. :)

Edit: Look for the gunsmiths who work on single action revolvers in your area. When you vist thier shop/store be sure to comment on their work. A good craftsman always likes feedback. Who knows, you just might want to pick up a nice Ruger Vaquero in .45 Colt while you're there. :)
