Hello all! New to this forum and looking for some information. I am a budding S&W revolver collector. Came across a model 657 (no dash) 6 inch barrel in a local gun shop in MA. Asking price 750 clams. It has some aftermarket houge grips that just look wrong! Otherwise I would place the gun in the very good category. It is mechanically perfect but has some cosmetic scratches, a nick or two, but no pitting or rust. Two questions. Is the asking price reasonable? Also, what would the correct grips be and what might those cost? Thank you In advance for any information provided. Seems like there are a lot of very knowledgeable people here willing to share great information.
