Well.......
The Model 28, separating itself from all the other N-frames, has the extremely dull, plain, "working man's" finish and it has a very bland top strap with none of the finishing touches we've come to know on Smith & Wesson revolvers.
However, along with the "Governor" and the X-frames, let us not so quickly forget the horrific "Bodyguard" and, well, at the risk of offending -- any of the hammerless snubbies (Centennial and the like) or the frame-shrouded hammer snubbies. While some may really enjoy that look, I think we can subjectively (mostly!) agree that all of these are easy example of Smith & Wesson revolvers that are far uglier than a solid, bruising Model 28.
