Overview
The Smith & Wesson 4566TSW is a subcompact semi-automatic pistol chambered in .45 ACP, introduced by Smith & Wesson in 2000. 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 steel frame and a 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.
