The cartridge was developed by Smith & Wesson in 1990. Because of the strong recoil of the 10 mm car , the FBI had downloaded the cartridge and thus practically created a 10 mm "light". Since the 10 mm car had also been criticized for having too long a case, the fact that the remaining amount of powder also fit into a smaller case was used. Smith & Wesson developed the cartridge, the caliber remained the same and only the cartridge case was shortened.
With a shorter case, this new cartridge could then also be loaded into smaller pistols that were originally designed for the 9 mm Parabellum caliber . The .40 S&W, along with the Winchester ammunition factories, was introduced as a newly created product at the 1990 Shot Show in the United States . It has also found its way into several countries outside the United States, such as Canada , Australia , Jordan (CTU Anti-Terrorism Unit) and the federal police authorities in Brazil . It offers about 40% more energy than a 9 mm Parabellum at normal pressure. The cartridge is also available as a subsonic version.
There was a trend among law enforcement agencies in the mid-1990s to favor .40 S&W versus 9mm Parabellum, which later reversed. The FBI switched back to 9mm Parabellum in 2015. The decisive factor was an increase in the performance of the 9 mm Parabellum through improvements to the projectile and the propellant charge. At the same time, the recoil of the 9 mm Parabellum is lower, which makes the firing more controllable, faster and more accurate.
