Developed in the late 1980’s and introduced in 1990, the 40 S&W was created at the FBI’s request for a pistol that would use a lower powered version of 10mm Auto. Because of the empty space in the 10mm casing, Smith & Wesson teamed up with  Winchester to shorten the casing and still produce the ballistics requested by the FBI and chose an overall length that allowed it to fit in a pistol frame commonly used in 9mm.

.40 Smith & Wesson Usage

Usage
While developed for the FBI, many Law Enforcement agencies also adopted the 40 S&W as their primary duty pistol cartridge until they started switching to 9mm Parabellum pistols in the 2000’s. The 40 S&W is still a choice for self defense by some civilians and some law enforcement departments globally and is used for IDPA competitions.
The 40 S&W was developed after the “1986 FBI Shootout” in Miami, FL, in which FBI agents armed with .38 Special and 9mm handguns were involved in a shootout with 2 bank robbers resulting in the deaths of 2 FBI agents and the wounding of 5 of the 8 agents involved. Both bank robbers sustained multiple hits from the agents’ duty weapons and continued to fight, which led to the quest for a better cartridge for standard issue.
