I have long wanted a set of genuine Sambar stag grips for my First Series Colt Woodsman. Some years back I ordered a set on ebay but they were way too thick and they totally changed the look and feel of the pistol. Fortunately the guy had a return policy. Then I tracked a set of really nicely aged ones that ultimately went for more than I paid for the gun; couldn't justify those!
Around Christmastime I found another pair on the bay, as nicely matched as any I've seen; very similar texture on both sides. The seller graciously supplied me with the measurements, which were just a very few thousandths over that of my OEM wood grips. Still, they were expensive, and I was kinda gun shy from the first pair I'd tried. One day I checked the listing and he was offering 20% off, free shipping, and a 14 day return privilege; couldn't pass that up!
Long story longer, I love them! They're beautiful, the gun looks great and feels really good in the hand; in fact I think the slightly thicker grips improve the feel, for me anyway. So here she is at last; the faux stag grips she had been wearing went on ebay the next day...
