The Zagi M-91 is an Croatian insurrectionist submachine gun.


The year was 1991. The dissolution of Yugoslavia left Croatia with little weapons to arm their troops in time for said country's war of independence. An embargo prevented the newly formed state from legally buying weapons from across seas, which left Croatia with no choice but to design their own weapons, leading to the Zagi. The weapon, despite being based on dated designs, was actually fairly robust and reliable, and apparently, liked by its users. Interestingly enough, some of these weapons ended up in the hands of some Muslim fighters, desperately in need of weapons.

Design DetailsEdit

The M-91 is based on the Sten, known for its simplicity and ease of production. The magazine used in the M-91 is based on the magazine used in the famed MP40; a double-stack 32 round magazine. The weapon's collapsible stock visually resembles the stock on the M3 Grease Gun. In spite being based on dated designs, the lower receiver of the M-91 is actually made of plastic.


  • The weapon is possibly named after Zagi, a squirrel mascot of the XIV Summer Universiade, held in Zagreb in 1987.
