Overview
The Smith & Wesson Model 4506 is a full-size semi-automatic pistol chambered in .45 ACP, introduced by Smith & Wesson in 1988. It is part of Smith & Wesson's Third Generation semi-automatic line, offering the proven .45 ACP cartridge in a modern double-action platform that combined the stopping power favored by .45 enthusiasts with the operational advantages of a DA/SA trigger system. The pistol features a stainless steel frame and a stainless steel slide, providing a durable platform designed for years of reliable service in both duty and civilian applications. competing against established .45 ACP platforms like the 1911 and SIG P220, these pistols offered higher capacity and double-action operation that appealed to agencies and shooters wanting modernized .45 ACP duty guns. In S&W's Third Generation numbering system, this model's designation indicates all stainless steel construction.
