The Vytis submachine gun (Lithuanian: Pistoletas-Kulkosvaidis Vytis) is a Lithuanian submachine gun that was designed by Algirdas Petrusevičius in 1990 and produced by Vytis from 1991 to 1993. Envisioned as a guerrilla weapon, the Vytis was supplied to the armies of a then-newly independent Lithuania.
In 1990, Lithuania's independence from the Soviet Union was restored, although safety was nowhere near assured. As a means of self-defense, a local patriot by the name of Algirdas Petrusevičius decided to design a simple submachine gun that was easy to produce, with small mechanic shops and simple fabrication works being able to churn out these weapons in great quantities if required.
Petrusevičius designed the first version of this submachine gun in a few months; it was chambered for 9×18mm Makarov to take advantage of the massive stockpiles of 9×18mm Makarov ammunition meant for police use. He then christened it the Vytis after Lithuania's coat of arms. He designed two improved versions later on and would then set up the state-owned Vytis company to produce the improved versions in 1991. Production ended in 1993; production numbers of all versions of the Vytis are not known.
The Vytis was an AK-derived submachine gun chambered for 9mm ammunition. It was optimized for mass production and was intended to be able to produced by small mechanical workshops and fabrication plants. Most versions were fitted with side-folding stocks and fed from 32-round stick magazines; it was apparently possible to shove up to 36 rounds in the magazines at an increased risk of jamming.
Prototype version designed by Petrusevičius as a proof of concept. Only one was produced and it is not known to exist today.
First production-optimized version. Chambered in 9×18mm Makarov.
Second production-optimized version. Chambered in 9×19mm Parabellum; said to look completely identical to the Vytis-2. Said to "only be feasibly obtainable through commercial sources in Finland and Sweden".
