The Submachine Gun (SMG) took shape in World War 1 (1914-1918) and was perfected during World War 2 (1939-1945). It has since remained a viable component to army operations worldwide and has found a special place in the inventories of special forces, police and civilian shooters alike. One of the most famous modern examples of the submachine gun remains the German Heckler & Koch MP5, favored by many fighting forces of the world including special ops troops.
PT Pindad of Indonesia, a notable gunmaker in its own right, developed the "PM2" series as a submachine gun for police and special units. It is chambered for the popular 9x19mm Parabellum German pistol cartridge and fires from either a 20- or 30-round detachable box (straight) magazine from a blowback / open-bolt action. A fire mode selector allows for various modes of fire to be achieved and other controls are conventional - magazine release, bolt catch release, etc...
The general arrangement of the weapon is traditional with the magazine well ahead of the trigger group and the pistol grip aft of the action. The shoulder stock is skeletal to save on weight and hinged to fold out of the way for compactness. The charging handle is set to the right side of the frame (it remains fixed when the gun is fired according to Pindad). A ribbed forend allows for a firmer hold of the weapon at the barrel section. The PM2 borrows the adjustable iron sighting arrangement of the Pindad SS1 series assault rifle though a section of Picatinny rail (Mil-STD-1913) over the receiver supports the installation of optics. Construction of the submachine gun includes hard anodized aluminum alloy.
Three major versions of the PM2 series weapon exist: the PM2-V1 is the primary, standard model with a 3.18kg operating weight and 625mm overall length. The PM2-V2 is a suppressed form, slightly heavier at 3.45kg and longer at 720mm. Both versions sport a collapsible stock. The PM2-V3 has a foregrip and it measures between the V1 and V2 lengths while the grip handle and shoulder stock differ in design.
Beyond its acceptance by the Indonesian Army and special forces troops (KOPASSUS), the PM2 has seen adoption by Timor Leste (Timor).
