The FEG KGP-9 Submachine Gun (SMG) emerged from the Eastern Bloc nation of Hungary during the latter stages of the Cold War period (1947-1991) in the later part of the 1980s. The weapon became a no-frills design which saw no military export nor service outside of the country, being issued primarily to Hungarian military and security forces for close quarters combat / defense. Manufacture was handled locally by Fegyver-es Gepgyar (FEG) (founded in 1891) and involved casting-reinforced pressed steel construction.
At its core, the KGP-9 was a highly conventional SMG through-and-through, firing the readily available 9x19mm Parabellum German pistol cartridge favored by the West (instead of any Soviet-inspired round). The internal action relied on the proven blowback principle utilizing an open bolt design in which the firing pin interacted with a hammer. The outward design was relatively clean and fee of obstructions, having a rectangular receiver and smooth forend. The barrel was shrouded for most of its length though, rather interestingly, this assembly could be replaced by a longer barrel to increase engagement ranges and create a de facto carbine assault weapon out of the base SMG. The wire shoulder stock was set on a hinge to allow it to be folded away (over the receiver) for a more compact footprint. A shoulder strap could be affixed for easing transport of the weapon.
The feed system relied on a straight, spring-loaded detachable box magazine and the component was inserted ahead of the trigger unit - the box holding up to 25 rounds of 9mm ammunition. Rate-of-fire reached 900 rounds-per-minute with a muzzle velocity of 1,280 feet-per-second. Sighting was handled by a standard front-and-rear iron arrangement. The ejection port was situated along the right side of the frame with the charging handle found on the left side.
Beyond the standard KGP-9 assault weapon was the KGPF-9 which was restricted to Semi-Automatic-Only (SAO) fire for sale in the civilian marketplace.

Rounds are automatically ejected from the breech, a new cartridge stripped from the feed and set in the chamber, and rounds are continuously fired so long as the trigger is pulled and an ammunition supply exists.
Gas pressure from the rearward movement of the ignited cartridge case provides the needed bolt movement, ejecting the spent case and stripping a fresh case from the magazine.
