The HAFDASA Z-4 is a submachine gun of Argentinian origin and is chambered in 9mm and .45 calibres. It has an aluminium lower receiver and is fed from a wide box magazine (50 rounds for 9x19mm Parabellum rounds and 40 rounds in .45 ACP). Its magazine insert has a dust cover that folds open forward to form a grip shrouding the front of the magazines. The Z-4 was available with a full rifle stock and even outperforms many modern submachine guns.
They were originally semiautomatic, although it is known that some were modified at the factory for automatic fire. Those of caliber 9mm had a magazine capacity of 50 cartridges, while the .45 model stored 40 rounds, a high capacity, especially for the era. The magazines are small in size, due to a design using two internal double-stack columns, and a feed selector to choose which column to feed from. Placing the feed selector in its central position prevents the weapon from firing. The Suomi KP-31 Schillstrom 50 round "coffin" magazines used a similar dual-doublestack design, but lacked the column feed selector.
