This is a very nice all original Smith & Wesson 4506 semi auto pistol chambered in 45 acp. Mechanically this pistol is in excellent working order and is sure to be a great shooter.  There is a department issue number stamped on the right side of the frame. This pistol comes with one original 8 round magazine. This is a great example of a collectible pistol that was at one time the work horse of American law enforcement!
