Smith & Wesson 4506-1 pistol chambered in .45 ACP. This semi automatic pistol is a traditional double-action/single action pistol. It features a 8 round box magazine, a 4 3/4" barrel, and comes with both front and rear sights. The stainless steel surface shows some light scratches but cosmetically this pistol is in great condition. Mechanically, this pistol works as it should. Bore is bright and mirror like. Great pistol for a Smith & Wesson collector, or even a home defense pistol.
