To me that price seems a little bit high, but not by much. The grips may well add the extra value. I have a 6" 14-4 that I just bought, and it was a lot cheaper than $650. It's in great shape with a little wear on the bluing, but no scratches or dings whatsoever. I don't know what brand of target grips it has though, I believe they are just some generic set. No markings or numbers on them at all, just a little sticker that reads "Made In Phillipines". Pretty sure they aren't factory S&W
I attached a pic of it.
