Wrong approach for that piece...
I could always just grip the daylights out of thing.
Single actions in the recoil range of the .44 Magnum (and above) only need to be held firmly. Control enough to not drop the piece, or have it hit you in the head is enough. A bit more that that is helpful, but not absolutely needed.
The recoil level and the shape of the grips, plus the need to cock the hammer each shot means guns in that class are repeaters, not rapid fire guns. Accurate
rapid fire is extremely difficult for most people. You don't shoot them like you do DA revolvers or autopistols. They aren't designed for that.
Old time cowboys and gunfighters could do, and today we can still do some excellent accurate rapid fire with single actions, but generally, NOT at the power level of the .44 Magnum. Cowboy action shooters shoot embarassingly light target loads, because being fast helps win matches. When you are shooting heavy power, forget fast with single actions. At least, if you want to be accurate.
Let the gun roll in your hand, let the muzzle climb to the sky, then haul it back down, cocking it for the next shot. With a little practice, you will automaticly adjust the gun in your hand back to a shooting grip.
Even lighter ammo will do this, just not as much, so recovery time is a bit quicker. For my hands, the oversize rubber grips are just the thing. There are lots of aftermarket grips in wood and other materials, but to be certain of the best, a custom gripmaker will size them to you. Costs a bit, but after all, how many of them are you going to buy in your life, anyway?
If you find something you want to buy off the shelf or order, make sure it is for YOUR gun. Super Blackhawks do not have the same grip size as Blackhawks. The grips do not interchange.
