I replaced the rubber hogues with the older style insert grips on my GP-100 5" 357mag. I got the walnut inserts from Chig's grips and like the way they look. The inserts were about $22. He has a wide variety of colors and wood. He makes them himself. The only downside to replacing the black rubber hogues is I have very large hands and the rubber grips kept my middle finger knuckle from touching the trigger guard and the "old style" doesn't. So it takes some abuse.
