Beretta Sub PM 12A/S

General description

The Beretta PM 12S sub-machine gun is a 9 mm Parabellum blowback weapon which has both semi-automatic and full-automatic fire capabilities.
The telescopic bolt, which encloses the barrel (200 mm long) for three quarters of its length, makes the weapon very compact and reduces to a minimum the upward movement of the muzzle during firing.
The front grip, the magazine housing, the trigger guard with firing device and manual and automatic safety devices are all in a one-piece assembly and are integral parts of the receiver. This gives solidity to the weapon and ensures good performance over the years.
Longitudinal grooves along the whole length of the receiver allow excellent sliding of the bolt even in extremely adverse conditions (fall of the weapon in mud and exposure to dust and sand).
The PM 12S's sturdiness and its total reliability in different latitudes can easily be seen in the general structure of the weapon and in the dimensions of its component parts, as also in the extreme simplicity of design and assembly.

Devices and controls

The selector device allows for an easy selection of three positions, namely: "manual safety" (S), "single shot" (1), "full automatic fire" (R), without any need for removing the hand from the grip.
The automatic safety, which locks the trigger and the bolt in its closed position, safeguards from accidental firing if the gun is dropped and precludes firing if the grip is not firmly held.
The fixed firing pin can strike the primer only when the cartridge is fully chambered, avoiding accidental firing, since the weapon fires from the "open bolt" position.
The front sight, adjustable in elevation and windage, and rear sight with 100 mt. or 200 mt. flip aperture allow accurate aimed fire and are well protected from impacts.
The sturdy folding butt can be safety locked in the "open" position. When folded, the butt runs along the side of the receiver in the most practical position.
The exterior surfaces of the weapon, finished (after phosphate treatment) with epoxy resin coating, guarantee the best possible protection against corrosion and maximum resistance to wear and abrasions.
