The Pleter submachine gun is a submachine gun created in 1991, when the dissolution of Yugoslavia left Croatia with few weapons to arm their yet to be formed military in the midst of Croatian War of Independence. The embargo prevented the newly formed state from legally buying equipment abroad, the first choice was to try to design and produce some new weapons locally, mostly based on second generation of submachineguns (like STEN gun or MP40).

The Pleter (named after the Slavonian town of Pleternica) was produced in the local factory OROPLET, heavily copied Sten Gun characteristics, despite having a vertical rather than horizontal magazine. These include the removable barrel assembly, the bolt and recoil spring, and the open bolt firing mechanism. Prototype models had handle and trigger pack cover made from wood, but in the serial production it was decided to use ones made from plastic. Barrel assembly was simplified compared to Sten gun, it was fixed by inbus screw, and to further simplify the construction, safety and fire selector was omitted. It was equipped with only simple sear/trigger/spring combination, making it open-bolt full auto only, but due to the relatively low rate of fire, skilled operator could fire single shots by quickly pulling and releasing the trigger.

Moreover, just like the Sten, the Pleter could also be fitted with a silencer, and there was a special model made with permanently fixed silencer attached ( called "Pleter 91 Prigušen" = silenced )

Fixed front and back sight that cannot be adjusted produced some criticism from the users. The magazine well was designed to accept the direct copy of Uzi magazine. This type of dual stack, dual feed type magazine is considered one of the improvements this gun has in comparison to the original STEN gun or similar ones that used dual stack, single feed magazines, that are often more prone to jamming and harder to load. The butt stock shape was apparently influenced by another similar gun of World War II vintage, the Grease Gun.

Out of probably dozen domestically designed and produced submachine guns from the 1991. the Pleter proved to be quite good insurgency weapon, which somewhat filled in the gaps of the undergunned Croatian Army and was suitable for the combat environment of the Yugoslav Wars. Some examples may also have oozed into Kosovo to see action in the 1999 war. The exact number of the produced Pleter guns is not published, but the ones that were in the logistic reserves of the Croatian military were destroyed after the war in coordination with the military police, so today this gun only exists in small numbers.
