Pachmayr Presentations are excellent quality, but it depends on the piece. I tried a pair on my 625JM (unlike some, I don't like the Miculek grips), and they looked good, but didn't hold so good for me. Right now I have uncheckered tulipwood two groove Spegal boot grips on , which are surprisingly comfortable to me, my pinky wraps around beneath and comes on the inside rear corner. I have Pachmayr Grippers on a K frame and on a J frame, and they do fine.
