I have a Super Blackhawk with a 4 5/8" barrel. With max loads and factory stocks it is a vicious kicker, knocking a bruise on my finger where it rests behind the trigger guard. I bought the aforementioned rubber stocks from Pachmayr, and it made the recoil tolerable, but not pleasant. I decided to try something else, so I got a Bisley in .45 Colt with a 7 1/2" barrel, and then sent it to Hamilton Bowen for shortening to a 5 1/2" barrel and tuning. What a difference! With factory stocks and hefty loads of WW296 under 300 gr. LFP's it is a pussycat compared to the SBH. The Bisley grip is the best one in a Single Action revolver in my opinion. If you're going to change, go with the Bisley. Brownells has a kit that has the Bisley grip frame and trigger/hammer for converting the Blackhawk to the Bisley.
