Another 645 question…

[Federalis]

Will an adjustable sight for the 4506 fit the earlier 645? I've seen a few pics of model 645s with what appear to be the adjustable sights that come on the 4506s? Just curious 'cause the stock sights that come on the 645s are scarce as hen's teeth, sorta speak…

If your 645 was originally built with an adjustable rear sight then yes, a 4506 adjustable rear will fit your 645.

If your 645 was shipped with a fixed rear sight blade and that's what is broken and you cannot source then no, a 4506 rear sight will not help you.

You could have a new cut made on your 645 to install a Novak fixed rear sight.

Thank you sir, yip it came with a fixed sight blade so I guess I'm gonna have to look for one of those puppies…
