I got a set of grips for my P6 a couple of years ago and they don't hold up well at all. Not on a carry gun anyway. The wood used is not very dense so it dents easily and the finish isn't robust. I started out pretty pleased with them as they looked great and felt great even if they were less dense. Now I'm thinking of going back to the original plastic grips or ordering from someone else.
I have gotten their custom grips from them for my Makarov, Bersa Thunder and CZ82 and have been satisfied on all three sets. There was some very minor difference in grain and color, but nothing very noticeable. Mine have held up well even the one on the CZ82 in the glove compartment. The biggest problem I had with them was with having the post office deliver them to me without my signature as no one else's would do. Went round and round with them on that when they threatened to send them back to the sender. Long story.
