Sternmeyer MP10

The Sternmeyer MP10 (German: Maschinenpistole 10), also known as the Sternmeyer Series 10 Pistol, is a multi-caliber machine pistol produced by the defense manufacturing corporation, Sternmeyer Waffenfabrik. It features a dual magazine system which can feed ammo to the firing chamber in alternating or selecting patterns.

Originally designed and commissioned for use by the German Bundeswehr, the MP10 emphasized maximum versatility within a compact form—as such, it was a popular firearm among both public and private security groups in the years predating the Fourth Corporate War.

Design details
The MP10 is a modular, select-fire weapon with lever-delayed blowback operation, contributing to the sense of low-felt recoil and allows for the usage of high pressure ammunition. The firearm is fed from two separate magazines—the primary one housed within the pistol grip, and the secondary situated in front of the trigger—which can be manually selected via a two-level switch. For the base MP10, the primary magazine is typically a 17-round detachable box loaded with 9 mm caliber cartridges, such as the 9×19mm Parabellum or .38 Super. When firing from this magazine, the MP10 can be switched between a semi-automatic or a three-round burst mode. The secondary magazine is usually loaded with more specialized cartridges such as beanbag rounds, pepperball rounds, breaching rounds, or—if confronted by a heavily-modded cyberpsycho—armor-piercing or high-explosive rounds; this magazine can only be fired from in a semi-automatic setting.

Conversions to other calibers and barrel lengths can be performed in mere minutes without the need of a specialized armorer, and using only a standard hex wrench. This action consists solely of changing to the appropriately chambered barrel and bolt, optionally replacing the brass deflector, and inserting the appropriate magazine.

The MP10 features smart system technology and can be paired with a specific user through the use of both a biometric reader and fingerprint scanner. Once paired with a handler, the MP10 can only be used by that individual and will trigger a safety lock in the hands of anyone else; this can only be bypassed through a full system reset or with a modified subdermal grip. In addition to user authorization, the MP10 features a weapon status tracker, which displays selected ammunition type, firing mode, ammunition count, and the number of shots fired within a specified time frame. There is also an optional Target Control module, through which the weapon can be controlled to fire only toward a recognized or “permitted” target, such as armed individuals, while locking if aimed at unarmed or unauthorized targets.

Trivia
The MP10 is based on the Lawgiver Mk. II from the 2012 film Dredd.
