The Smith & Wesson Model 4506 is a third-generation semi-automatic pistol from Smith & Wesson's 4500 series of handguns. The 4506 is chambered for the .45 ACP cartridge and, with the purchase of special springs, the stronger .45 Super. It is constructed almost entirely from stainless steel and is thus extremely resistant to harsh weather conditions. The 4506 is a traditional double-action/single-action pistol. The first shot is fired in double action mode. Each subsequent shot is fired single action mode. It features one-piece Xenoy wrap-around grips with either a curved or straight back strap. The 4506 was produced from 1988 to 1999.

Like most 3rd generation Smith and Wesson semi automatic pistols, the 4506 features a combination safety lever and decocker mounted on the slide, a plunger type firing pin safety, a magazine disconnect and a pin mounted, pivoting spring actuated external extractor.
