Analogous to the Israeli [[Uzi#Military variants|IMI Mini-Uzi]], the PM-9it has the same [[telescoping bolt]] as the Mini-Uzi, but differs in its appearance, operational useoperation and handling.
The JSDF uses the PM-9 as its official submachine gun, although some of its special-forces units now use other weapons. The [[1st Airborne Brigade (Japan)|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.<ref>{{cite web|url=http://www7b.biglobe.ne.jp/~gunblazesix/moe_9mmsmg.htm|script-title=ja:ミネベア 9ミリ機関けん銃|language=Japanese|accessdate=2008-09-01}}</ref><ref>{{cite web|url=http://militaryroom.chips.jp/newpage65.html |script-title=ja:9㎜機関拳銃 |accessdate=2009-01-13 |language=Japanese |url-status=dead |archiveurl=https://web.archive.org/web/20091021013400/http://militaryroom.chips.jp/newpage65.html |archivedate=2009-10-21 }}</ref> The PM-9 is reported to be in use in the JGSDF's Special Forces Group.<ref name="Report">{{cite web|archiveurl=https://www.webcitation.org/6CWqH9jnF?url=http://jieitaisaiyou.web.fc2.com/tokusyu.html |url=http://jieitaisaiyou.web.fc2.com/tokusyu.html |script-title=ja:陸上自衛隊唯一の特殊部隊 特殊作戦群の解説 |language=Japanese |accessdate=2012-11-28 |archivedate=2012-11-29 |url-status=dead }}</ref> The [[Japan Air Self-Defense Force]] (JASDF) uses it when conducting base security.<ref>{{cite web|script-title=ja:9mm機関拳銃|url=http://www.avis.ne.jp/~hide-y/guntrue/guntruemain.html|accessdate=2009-11-04|language=Japanese}}</ref>{{Clarify|date=November 2011}}
Although PM-9 nomenclature is widely used among non-Japanese firearms communities, there hadhave been no known public records or confirmations of its official use. As such, the firearmit is mostly referred to in its full name or in its shorthands, and less so in the supposed alphanumeric nomenclature in Japanese texts.{{cn|date=December 2019}}
