PM-84 Glauberyt
Fabryka Broni Radom · Submachine Gun · In Production · 1984
Also known as: FB Glauberyt, wz. 1984
Overview
The PM-84 Glauberyt is a Polish blowback-operated submachine gun chambered in 9x18mm Makarov, introduced in 1984 to replace the PM-63 RAK in service with the Polish Armed Forces. Firing from an open bolt, it features a compact machine-pistol layout with a side-folding wire stock and a forward-folding foregrip, giving it personal-defense-weapon handiness for vehicle crews, paratroopers, and police. Later variants such as the PM-84P, PM-98, and PM-06 rechambered the design to 9x19mm Parabellum and added modern accessory rails.

Notes
The militaryfactory listing cites a closed-bolt action and a 105 m/s muzzle velocity; the original PM-84 in fact fires from an open bolt and the 105 m/s figure appears to be a transcription error for the 9x18mm cartridge, which leaves the muzzle at roughly 320 m/s.
Background
Developed at the Radom arms works as a successor to the recoil-operated PM-63 RAK, the Glauberyt kept the RAK's compact one-handed handling while moving to a more controllable closed-stock layout. Its name derives from Glauber's salt, a nod to the chemical industry that funded part of the program.
