It's strange. With CNC machinery making everything you'd think it would be closer. I worked for Cimarron, and they had some Model P's for a year or so that had 2-piece screwed on checkered plastic grips with a medallion. They had some internal spacer thingies so they would fit on the grip without needing a locator pin. Well the design was crap. They cracked and broke fairly easily, and too easy to crack when tightening the grip screw. Some came out of the boxes new with cracks. Well Uberti supplied a bunch of replacement grips, and they all fit perfectly! So dang, why can't they do that with the wood grips? Since you are refinishing, you should be good to go. A lot of people have changed theirs out for faux-ivory and such, so shouldn't be too hard to find someone with an extra set. Good luck.
