I bought a pair of combat grooved checkered rosewood grips for my GP100. One word: JUNK! They were a horrible fit. For that kind of money, there is no excuse! The grips come in 2 halfs and when you put them together, the finger grooves didn't line up at all.
I have one suggestion for you: Hogue! They have superb wood grips. They are one piece and look and feel fantastic. These are the exact grips that replaced my Eagle Grips:
