Will a sight from a five screw 27 fit my 627?

Hello, I have been looking for a rear sight for my 627 model of 1989 and I found one that the seller says is from a five screw 27. Will this fit ? Thanks in advance for your help. -mike

This is the type in the links you need with the rounded front edge.

The screw hole probably will not line up with a flat front from an old model 27

Thanks for the reply. From all of the pics I've seen of the model 27 model of 1989's with intact sights, they have a flat front end. It appears from what I see on numrichs website all 27's are compatible, but I'm not sure if it being a five screw makes it a pre 27.... and if pre 27s are compatible with other 27s. Going crazy here, lol
Mine should have he checkered baxkstrap. The one for sale is checkered.

IMHO I would say no the rear sight from a five screw will not fit your 627 model of 1989.

Smith changed the hole location for the front attachment screw, not sure when, but surely after 1956.

I measured my 627-0 from the rear blade to the center of the anchor screw as good as could, estimating the center of the screw. It measured about 2.282. I measured a pre model 27, serial 15912x the same way and it measured 2.153.

I don't know when they changed this specification, but my guess would be that you need to find a sight from later gun than a pre 27, say 27-2 or later to fit the 627

The 5 screw era rear site will not fit.
Is your 627 a "No dash" or ?
Round site leaf cut at front or old style like pictured above ?

If its a no dash a checkered rear site from a 27-2 , 27-3 should fit.

Yep, it is checkered and squared on the end....

Nice! Looks exactly like mine.... well.. except mine is missing the rear sight, lol. (And my combat grips are a bit different)

Yes. It has a B-square mount on it with a nice condition Ultra Dot. My grandfather put it on when he bought it and over the years the sight went missing. I want to restore it to original, but haven't had any luck finding a rear sight.

Just looked, it's a 627-0.
