The PM-63 is a sub machine gun of Polish origin. It was developed in the late 1950's as a personal defence weapon for rear echelon troops. For export versions in different calibers were developed, but were never placed in production.
The design is a mix between a pistol and sub machine gun. It uses a straight blowback mechanism and fires from the open bolt position. The unique design feature of the PM-63 is that instead of a normal internal bolt a slide is fitted. The magazine is inserted into the pistol grip. A retractable metal wire stock and foldable forward grip are fitted. To make the weapon more controllable a spoon shaped compensator and a inertia based rate reducer are fitted.
The PM-63 fires the 9x18mm Makarov round from double stack 15 or 25 round magazines. Fire modes are semi-automatic and automatic at a rate of fire of 650 rpm. The maximum effective range is quoted as 150 meters. With automatic fire this range is much reduced.
The main user of the PM-63 was Poland and small quantities were exported to East Germany, Vietnam and various Arab nations. An unlicenced copy was produced in China as the Type 82 and has been exported to several nations with close ties to China.
The PM-63 is a sub machine gun that is easily identified by its many unique features. The external slide, foldable forward grip and spoon type compensator make it easy to identifiy. A PM-70 in 9x19mm and PM-73 in .380 ACP have been developed but were never produced in quantity.
