196 Minebea PM-9
https://en.wikipedia.org/wiki/Minebea_PM-9
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?)[2] or as the M9,[4] 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. The 1st Airborne Brigade and the Western Army Infantry Regiment are the only special forces units in the Japan Ground Self-Defense Force (JGSDF) known to be armed with the PM-9 as the brigade's main submachine gun.[5][6] The PM-9 is reported to be in use in the JGSDF's Special Forces Group.[7] The Japan Air Self-Defense Force (JASDF) uses it when conducting base security.
The PM-9[3] is produced by the Nippon Miniature Bearing Company, otherwise known as Minebea. The design is based mainly on the Mini-Uzi submachine gun.[9] It was adopted in 1999 for non-frontline forces such as vehicle drivers, artillery personnel, some of its special forces units,[10] and some commissioned officers who were given priority for better equipment.[11]
Though it has been the official submachine gun for more than a decade, as of 2009 JSDF officials are looking at a possible replacement, as it is planned to phase it out in the near future. One possible replacement is the Heckler & Koch MP5.[10] JSDF troops assigned to guard duty on both Japan Maritime Self-Defense Force (JMSDF) and JASDF garrison bases had their PM-9s replaced with other high-performing submachine guns,[12] and the JGSDF will also eventually replace the PM-9
