Picked up the 625-2 (Model of 1989) today.
It was missing the whole rear sight assembly.
Found the proper length/screw whole replacement.
However the replacement needs a rear elevation stud, and a correct height blade: 0.106.
First question is: Are all the elevation studs the same? Square bottom? The channel has a rounded front on this revolver if that makes a difference.
Second question: The rear blade works fine on the replacement. Do I just need the blade or the whole assembly (windage screw, nut and blade)? Any good links on how to replace it and not lose the detent?
Thanks!
