Also known as: Model 4004

Overview

The Smith & Wesson Model 4004 is a full-size semi-automatic pistol chambered in .40 S&W, introduced by Smith & Wesson in 1991. It is among the first pistols chambered for the new .40 S&W cartridge, which was developed jointly by Smith & Wesson and Winchester as a shorter, more manageable alternative to the 10mm Auto after the FBI's experience with that round. these pistols arrived at exactly the right moment, as law enforcement agencies across America were transitioning from revolvers to semi-automatics and seeking a cartridge that split the difference between 9mm and .45 ACP. In S&W's Third Generation numbering system, this model's designation indicates aluminum alloy frame with carbon steel slide, full-size configuration.

Background

Smith & Wesson's Third Generation pistols used a sophisticated model numbering system where each digit conveyed specific information about caliber, frame size, action type, and materials - essentially encoding the entire specification sheet into four digits.
