25 or 625 fixed sight model

[Meeteetse]

This may be an obvious and simple question however I would like to know if S&W has ever built a fixed sight N-frame in 45 Colt? I cannot remember if the Thunder Ranch series ever came in 45 Colt. I am aware of the various adjustable sight model and I own several, but I was wondering about fixed sighted models.

What N-frame models in general have had fixed sights?

Thanks
