HS Produkt Kuna
HS Produkt Kuna is a Croatian submachine gun designed and manufactured by HS Produkt which is available in both 9x19mm Parabellum and .40 S&W.
The Kuna is available in a semi-automatic version for commercial and civilian sales, and as a select-fire sub-machine gun for military, law enforcement and government sales.
History
Development on the Kuna began in 2020 as a commercial project.The Kuna appeared first at the COP Internacional trade show in Sao Paulo in 2024 after HS Produkt won a contract with the Sao Paulo Military Police.
Later in 2025, it was revealed at EnforceTac 2025 and IWA OutdoorClassics 2025 under Springfield Armory branding.
Design
The Kuna was designed for the.40 S&W caliber and to withstand the strong pressures of that cartridge in order to obtain a strong and resistant construction and then gradually adapt to the weaker 9x19 mm Parabellum cartridge.One of the key details in the design is the single-roller delayed-blowback locking system. This leads to higher accuracy, less vibration and longer service life.
