The .40 S&W cartridge, commonly used in Glock 22 pistols and other firearms, is a powerful round developed in the late 1980s. This cartridge offers a balance between stopping power and magazine capacity. Various manufacturers produce ammunition for this caliber, offering different bullet weights and designs for specific needs, such as target practice or self-defense. The choice of projectile significantly influences the cartridge’s performance characteristics, affecting accuracy, penetration, and expansion.
The development of the .40 S&W cartridge filled a perceived gap between the 9mm Parabellum and the .45 ACP. Law enforcement agencies widely adopted this caliber due to its perceived effectiveness. The widespread adoption also spurred the development of various firearm platforms chambered for it, contributing to its continued prevalence. The cartridge’s history reflects the ongoing evolution of firearm technology and the constant search for optimal ballistic performance.
