The Minebea PM-9 Submachine Gun, known officially in the Japan Self-Defense Forces (JSDF) as the 9mm Machine Pistol (9mm機関拳銃, Kyumiri Kikan Kenjū) or as the M9, is a Japanese-made machine pistol. Based on the Israeli IMI Mini-Uzi, the PM-9 has the same telescoping bolt as the Mini-Uzi, but differs in its appearance, operational use and handling.The JSDF uses the PM9 as its official submachine gun, although some of its special forces units now use other weapons.
