I just bought a 4" Model 29-3 (serial No. AYD11**) and it has some sort of satin or matte looking finish, but it is definitely marked Model 29, not 629. The seller swears it is a nickel finish, and he bought it used. The price was right ($450), or so I thought. I was looking for a shooter anyway. It almost looks to be "in the white"?, but I'm just not sure. So, was it re-finished? or was there ever a factory electroless nickel finish on an M29? I'll get a picture up as soon as I can. Also, anybody ever seen grips like these before? Any information or insight is appreciated.
