My 89 5.5" 44 came to me with Pachmayr Gripper Decerators, but I've only shot about 135rds with them. They do well with recoil, but the finger grooves are an odd spread for my mid sized mitts.
I did pick up a set of Pach Presentaions for it.
I have Grippers on an old model Taurus 66 4" that fit me awesome, and found the Presentations work well for me on my 8" Python-so I'm hoping I can settle on one.
My Redhawk is on the way back from Ruger as we speak, and I sent it naked-fingers crossed it comes home with factory wood to try ;-)
