Hedrin, that is a really nice 657 you are getting and I also agree you didn't overpay.

Also, since you are a more "mature" person like myself, you might want to get yourself a gold bead patridge sight as a replacement for the dinged up red ramp sight. SDM makes some in .250 and .300 height that will fit your gun. You will have to drill the hole for the roll pin to slide though and mount the sight blade (your gunsmith can do this if you don't feel like doing it yourself). I find that those type sights are much easier to get a good sight picture with than the red ramp sights and have installed them on a couple of N frames I have that use the quick change sight system.
