Zaklady Mechaniczne Tarnow

The PM-84 Glauberyt is a Polish submachine gun designed at the OBRSM Tarnow facility. It was developed as a compact personal defense weapon for Polish military and law enforcement. The Glauberyt uses a simple blowback action chambered in 9x18mm Makarov with later variants in 9x19mm Parabellum. It features a folding stock and an integral foregrip for improved handling. The weapon is compact enough for concealment yet accurate enough for effective fire at close range. It was designed as a replacement for the earlier PM-63 RAK submachine gun.
