Might as well add this one to it. A four screw, Model 10-2 I picked up this week. It looked really rough in the case at the dealer's, but a couple of rounds with some Flitz, and a couple of coats of Ren Wax, and it at least looks presentable.
It came with a set of WELL worn mismatched diamond magna's that didn't number to the gun. The right side checkering was almost gone. I took them off and put them away, and put these aftermarket (Thai?) set I had around on. I later took them off and put a Hogue Monogrip on.
