Encyclopedic overview

The Heckler & Koch UMP (Universale Maschinenpistole, German for "Universal Machine Pistol") is a submachine gun developed and manufactured by Heckler & Koch. Heckler & Koch developed the UMP as a lighter and cheaper successor to the MP5, though both remain in production. The UMP has been adopted for use by various countries, including Brazil, Canada, and the United States. Some of the weapons saw limited service in the early years of the Iraqi insurgency, making them one of the more popular submachine guns being deployed by the U.S. military personnel in recent conflicts around the world.

The UMP can be converted from 9×19mm Parabellum, .40 S&W, or .45 ACP by changing the barrel, bolt, and magazine. The UMP was previously available in multiple calibres, however with a decline in global use of .40 S&W and .45 ACP, only the 9mm Parabellum variant is in production. Parts are still available for the .40 S&W and .45 ACP calibre variants.
