KGP-9
The KGP-9 is a Hungarian submachine gun used by Hungary's military forces and prison guards. Development started in 1986 when the head of the Hungarian Institute for Military Technology, János Egerszegi, drafted a proposal for a new sub-machine gun in 9mm Parabellum rather than 9x18 Makarov, the latter caliber being disliked by the counter-terrorist units of the Hungarian police.
