A sub-machinegun developed by Heckler & Koch in the 1960's. Derived from the famous G3 series of assault rifles, the MP5 used the same delayed-blowblack rollerlocking system. Originally chambered for 9 mm Parabellum, the venerable MP5 has also been rechambered for 10 mm Auto and .40 Smith & Wesson, with the latter being a preferred calibre of the FBI. Probably one of the most proliferous SMG's in the world, although it could be supplanted by newer submachineguns, due to the growing obsoleteness of 9 mm cartrdiges against armored targets.
