History of the Glock 22
Development of the Glock 22
The Glock was introduced in the early 1990s following the development of the .40 Smith & Wesson cartridge. Law enforcement agencies sought a caliber that offered more energy than 9mm while maintaining manageable recoil.
The .40 S&W cartridge was standardized by SAAMI to ensure safe manufacturing specifications.
As agencies transitioned from revolvers to semi-automatic pistols, the Glock 22 became one of the most commonly issued sidearms in the U.S.
