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to the 9mm parabellum, but with muzzle velocity exceeding all 9mm loads, and exceeding most standard loads of the outdated .45ACP cartridge, while having a standard magazine capacity of as many as 15 rounds (G22) as compared to the 7 round standard 1911 magazines, or the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.

A .40 cal is not a big fucking gun, it's an improved version of the 9mm. What it really is is a 10mm bullet, and packs more punch than the 9mm, but still allows for the same (high capacity) amount of rounds to be held in a clip. A favorite of drug dealers.

A caliber developed by Smith & Wesson for women and limp-wristed men, this cartridge is slightly more powerful than the 9mm but does not approach .45 ACP
That punk pulled a .40 cal on me! I took out my 1911 and blew his fucking brains out!

.40 Cal: Simply put, a big ass fucking gun. Usually a semi-automatic with no safety and a rubber grip handle. It will fuck you up.
