.40 S&W (no ontology)

From Mazeworld

.40 S&W (also referred to as 10x22mm) is a pistol cartridge developed in 1990 by firearms manufacturers Smith & Wesson and Winchester. It is a shortened version of 10mm Auto, developed from the so-called 10mm Auto "FBI Lite loads" ; reduced loads to dampen the severe recoil of a full-power 10mm. That load was then adapted to a shorter case. Much like how .357 Magnum is dimensionally the same as .38 Special except for case length, .40 S&W is dimensionally the same as 10mm Auto, but with a shorter case. To better visualize their relationship, one can imagine that .40 S&W is the "10mm Auto Special", or that 10mm Auto is the ".40 S&W Magnum".

While it is considered a viable alternative to 9x19mm Parabellum and .45 ACP, many are divided on whether it offers the best of both worlds (citing high capacity and stopping power), or the worst of both worlds (citing relatively high recoil and only marginal performance gains over 9x19mm and .45 ACP). Regardless of one's position on .40 S&W, it is a street-proven cartridge with numerous law enforcement agencies having adopted firearms chambered for this cartridge. It even found use in submachine guns; notably the famous .40 version of the H&K MP5, the MP5/40.
