I need some advice on where to get a part. I discovered my new to me 629-2 is missing a part. For lack of a better name I will call it a nut. Under the rear sight there is a groove cut to accept a thin piece of metal that is drilled and tapped to receive the height adjustment screw of the sight. I checked Brownell's, Midway, and the S&W site. Could someone give me a suggestion where I might buy this part and maybe the correct name for it.
On another note. At some time in the future I may want to install a Leupold FX-11 2x scope. I have never scoped a Smith before so could I have some suggestions about a base and rings please. Thanks, GG
