Also known as: Model 4043
Overview
The Smith & Wesson Model 4043 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. 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. 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 stainless steel frame with aluminum alloy slide, full-size configuration.

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.
