MP5

The MP5 is a 9mm submachine gun of German design, developed in the 1960s by a group of engineers from the West German arms manufacturer Heckler & Koch GmbH (HK). The company, motivated by the success of the Heckler & Koch G3 rifle developed a group of small arms consisting of four types of firearms (all based on the G3 design layout), where the first type was chambered in 7.62 x 51 mm NATO, the second – using the 7.62 x 39 mm M43 round, third – the intermediate 5.56 x 45 mm NATO caliber and the fourth type – chambering the 9 x 19 mm Parabellum pistol cartridge. The MP5 (short for Maschinenpistole 5) was created within the fourth group of firearms, initially known as the HK54. The weapon makes appearances in Grand Theft Auto: Vice City, Grand Theft Auto: San Andreas, Grand Theft Auto: Liberty City Stories, Grand Theft Auto: Vice City Stories, Grand Theft Auto IV, and Grand Theft Auto: Chinatown Wars. Each rendition has a variant in the GTA games. GTA Vice City and San Andreas feature a MP5A3. GTA Liberty City Stories features the MP5K which looks a little lengthier than the other renditions and in Vice City Stories, the SP89 (civilian version of the MP5K) makes an appearance. In GTA IV, the MP5 is heavily modified and resembles the look of a MP10. In GTA Chinatown Wars the MP5 is called the SMG just like any other rendition, and is an arguably a better substitute for the Micro SMG, holding a better rate of fire and more damage per round. All of the MP5 renditions hold 30 rounds per magazine.
