Hogue Monogrips
If memory serves, the grips that I purchased for my Redhawk should also fit your Super Red. They made the pistol (a 44 Mag) a bit more managable for me (my hands tend to sweat and made the wooden stocks slick.) I liked the Hogue grips better than the other rubber grips because whenever I handled the pistol, my hands didn't come away smelling of rubber.
I know that 454 must kick like a bastard, and if I were shooting it with the stock grips, that pistol would be all over the place after the first few shots. So I know that for me, the rubber grips would be a welcome addition.
There might be some aftermarket wooden one piece grips that could foot the bill for you, but I know the Hogue's worked for me. See if the gun store has a display model you can wrap your skinners around, so you can judge for yourself.
Good Luck!
