.40 cal

First introduced by Smith&Wesson in 1990. Ballisticly similar to the 9mm parabellum, but with muzzle velocity exceeding all 9mm loads, and exceeding most standard loads of the outdated .45ACP cartridge, while having a standard magazine capacity of as many as 15 rounds (G22) as compared to the 7 round standard 1911 magazines, or the awkward-to-hold 13rd G20. Despite the belief or most inexperienced with the round, the .40 S&W has noticeably more recoil then the .45ACP.

Ironically, Austrian manufacturer Glock beat Smith & Wesson to the dealer shelves in 1990, with pistols chambered in .40 cal.
