The bulk of the Extreme Duty rear sights intended for the S&W revolvers will fit the models that you have mentioned
There is no way to answer if the particular one in your hand will or will not fit
They say it will fit most N-frames. This morning I verified it will not fit the PC R8, because the screw holes are off.
Maybe the TR versions of this revolver will work?

That's a bummer; C&S should know what their product will work with and what it won't.They say it will fit most N-frames. This morning I verified it will not fit the PC R8, because the screw holes are off.
Another member also found that his C&S sight did not fit his R8. However the sight did fit his M27 Classic and his M29 Classic. So the problem appears to be with the R8, not the sight; apparently the R8 has non-standard sight mounting holes. Question is: why?
Adding to the confusion, I just saw a photo of a TR 325 with the C&S sight installed. No idea if this was a dop-in fit or had to be gunsmithed.

S&W changed the sight hole spacing at some time years ago. You have two choices: drill the frame to match the sight or drill the sight to match the frame.
I'd drill the sight, it's cheaper than the frame.

I think you are referring to 1967 for K-frames, 1993 for N-frames. I could be wrong about that though.

I have been installing that sight on S&W 'K' frames that originally came with the fixed rear sight channel. There I have to drill and tap the frame after milling out a channel for the sight to set in. If I recall correctly, I put one on a 'K' frame that originally had an adjustable sight and while one hole matched, the other hole had to be D&T'ed. I really like this sight. ............ Big Cholla
