Overview
The Smith & Wesson 4586 is a full-size semi-automatic pistol chambered in .45 ACP, introduced by Smith & Wesson in 1990. 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. The double-action-only trigger provides a consistent pull for every shot, simplifying training and reducing the risk of negligent discharge under stress - features that made DAO models popular with law enforcement agencies. 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.
