I currently do not own a 3rd gen S&W semi-auto and until today had not really thought too much about them. Then I made the mistake of stopping in a local gun & pawn that I have had good luck in the past. In the case was a 4506, a very nice looking pistol. I did not ask to see it so I don't know the dash number. It had one magazine and no box. Asking price was $675.00 but that is negotiable. I did look to be in very good condition. Thinking about going back tomorrow for a closer look. Is that price fair? Seems a little high after looking at some on GB. I 'd appreciate any input.
