H&K MP5 Series

The **MP5** (German: *Maschinenpistole 5*) is a 9x19mm Parabellum submachine gun, developed in the 1960s by a team of engineers from the German small arms manufacturer Heckler & Koch GmbH (H&K) of Oberndorf am Neckar.

The MP5 is one of the most widely used submachine guns in the world, having been adopted by 40 nations and numerous military, law enforcement, intelligence, and security organizations. It was widely used by SWAT teams in North America, but has since been supplanted by M16 variants in the 21st century.

In 1999, Heckler & Koch developed the UMP, the MP5's successor, but the UMP has not met the same level of success.

## Variants

* **MP5A1:** This model uses the SEF trigger group and no stock.
* **MP5A2:** This model uses the SEF trigger group and a fixed plastic stock.
* **MP5A3:** This model uses the SEF trigger group and a retractable metal stock.
* **MP5A4 and MP5A5:** These models are the same as the A2 and A3, respectively, except that they use the more modern ambidextrous trigger group.
* **MP5-N:** This model was developed for the United States Navy. It was the first model to use the ambidextrous trigger group and adds a threaded barrel for use with a suppressor.
* **MP5SD Series:** The MP5SD is a specialized variant of the MP5 with a built-in suppressor. This gives it a distinctive appearance with a longer, bulkier barrel. The silencer can be removed, if desired, permitting unsuppressed operation.
* **MP5K:** The MP5K is an ultracompact variant intended for discreet use by bodyguards or similar users. It features a dramatically shortened barrel with a vertical plastic foregrip and simple endplate at the rear of the receiver in place of a stock. The weapon is fitted with a sling swivel, allowing the MP5K to hang vertically out of sight under a jacket or coat. For compactness, the MP5K is generally used with a short 15-round magazine. Some models have the sights removed to facilitate rapid draw from under clothing with less risk of snags.
* **MP5K-PDW:** The MP5K-PDW is a compact variant designed to serve as a personal defense weapon for pilots, vehicle crews, and rear echelon personnel. It takes the MP5K and modifies it with an extended muzzle, capable of mounting a suppressor or flash-hider, and a folding plastic shoulder stock.
* **MP5/10:** This variant of the MP5 is rechambered in 10mm Auto. It was developed for the FBI after the Bureau adopted the 10mm as its standard pistol caliber in the 1980s. It features the same style of straight plastic magazine as the MP5/40.
* **MP5/40:** This variant of the MP5 is rechambered in .40 S&W. It can be identified by its clear plastic magazine, which sticks straight out rather than curving like the standard metal 9mm magazines.
