I found after doing a bit of shooting that the stock grips on my new Super Blackhawk were just too small. I got a set of zebrawood grips off Ebay, no brand on them. They're HUGE, but fit my hand well. They could use some refining as far as fit to the gun, but after shooting 50rds today I love them. They really help reduce recoil, and now I can place my pinkie on the grip which seemed to help accuracy. Not bad for $20.
