The PM-84 Glauberyt is a Polish submachine gun. It is a personal weapon intended for combat and self-defense at ranges up to 150 m with single shot or fully automatic fire mode. It features compact design, minimum overall dimensions, small weight, very good accuracy, and fire stability. It is designed for Heavy weapons platoons personnel and reconnoitering detachments, special anti-terrorist and police troops.

In service with the Polish military and police it replaced the earlier PM-63 RAK submachine gun.

Operation
The Glauberyt is a select-fire, straight blowback-operated firearm that fires from the closed bolt position. Its design influence can be seen to mimic the iconic Uzi. However it features a last shot bolt hold open/release like modern service pistols unlike any Submachine guns at its time. The PM-84/PM-84P also features ambidextrous charging handles on both sides (vz.61 Škorpion influenced). A 2 bar retractable butt stock tucks right into the side of the weapon. Magazine release is in the heel of the pistol grip. The Glauberyt feeds from 15-round flush magazines and 25-round extended magazines. Fire selector Z = SAFE, P = SEMI, C = FULL AUTO, sits above rear of the pistol grip. When the firearm is on SAFE, the bolt is locked and prevented from moving. A folding fore grip rests in front of the trigger guard (PM-63 RAK style), optional tactical flashlight/laser grip can also be mounted replacing the folding fore grip.

Modern PM-98/PM-06 variants utilizes a thumb magazine release. A new slot in the magazine is required to be cut out to work in the later Glauberyts.
