The Glock pistols chambered in .40 Smith & Wesson represent a significant segment of the Glock pistol line. Several models were initially designed to accommodate this cartridge, offering a balance of stopping power and magazine capacity within a relatively compact frame. These models include, but are not limited to, the Glock 22, a full-size duty pistol; the Glock 23, a compact variant; and the Glock 27, a subcompact option favored for concealed carry. The numeric designation typically indicates the order of introduction or development within the Glock product line.
The .40 S&W Glock models gained popularity due to the cartridge’s increased energy compared to the 9mm, which was considered a substantial advantage for law enforcement and self-defense purposes. The introduction of these .40 caliber Glock pistols provided agencies and individuals with a service weapon offering a greater perceived ability to incapacitate a threat. The cartridge’s adoption and prevalence have varied over time, with shifts in preference towards other calibers occurring as ammunition technology and performance evolved. Despite these shifts, models in this caliber remain a common choice for many.
