Are the wood grips that uncomfortable on the Super Blackhawk?
It depends entirely on your personal tolerance, and what loads you are shooting. And, it's the grip shape, and size, combined with wood that makes the difference for me.
I found the point to be at about 200+gr slugs and over 1100fps. Wood grips do exactly what Sam Colt meant them to do, give you a way to hang on to the gun, and still let it roll in your hand during recoil. This brings the hammer closer to your thumb for recocking, and was VERY useful design feature for one handed operation.
HOWEVER, as recoil goes up I found the slippage with wood grips allowed the back of the trigger guard to bash my middle finger. I learned this with a 7.5" Blackhawk in .45 Colt, back in the 80s, when I was experimenting with what are now called "Ruger Only" loads.
I put on a set of Pachmeyrs, and found the combination of filling in behind the triggerguard, larger overall size and the softer rubber did a better job of "locking" the gun into my grip. It still rolls in the hand, but not as much, and I don't get a bashed finger.
So, I put Pach's on all my Blackhawks, .357, .44 & .45. I have tried the Hogue hard plastic ones, didn't like them.
I also put Pachmeyers on my S&W N frames, for the same general reason.
Wood LOOKS good, even great. Rubber feels better to me, when you get above .45 COlt level loads, and doesn't seem to hurt anything at lower recoil levels.
Your experience may be different. Personal choice is all that matters.
