The MP5 was first conceived in 1964 as the MP54 (A.K.A. HK54). The prototype was first released in 1965. It was adopted by the Deutsche Polizei (German police) as the MP5, where many original examples still serve today. Since late 2017, the Brandenburg police have begun to replace it with the MP7A1, with several other federal states following since.
All MP5 SMGs are fitted with fire control groups capable of several modes of fire. There are two main variants - three-positional, which has safe, semi-automatic and full auto positions, and four-positional, which has safe, semi-automatic, burst and full auto positions. Burst mode fires two or three rounds at a single trigger pull (2 or 3 - depends on the exact model).
The MP5 can be fitted with fixed (MP5A2; MP5SD2) or collapsible (MP5A3; MP5SD3) stocks.
The MP5 features a cold hammer forged, 9-inch free-floated barrel, with a 1:10 twist rate. It is pressed and pinned into the receiver.
The standard MP5 uses 9×19mm Parabellum ammunition, but there are specialized variants chambered in more powerful .40 S&W and 10mm Auto. These variants can be spotted by different, straight magazines. There are 30- and 15-round proprietary magazines for each type of ammunition. There are also variants of the MP5 that use an integrated suppressor, designated as "MP5SD". "SD" is an abbreviation of the German word "Schalldämpfer" (literally, "sound dampener" (suppressor)). It has an integral suppressor and a vented barrel, which allows normal ammunition to be fired at subsonic speeds due to less gas pushing the projectile out of the barrel. Standard variants of the MP5 can be outfitted with suppressors as well.
On offer were various models, mostly based on stock style and trigger group, "SEF" being semi automatic and full automatic, and "0-1-3-D" being semi, burst fire and full. Burst fire comes in either 2 or 3 round bursts, so any MP5 with a burst option can use the 2 round burst.
The MP5K only comes in 9x19mm, and is the compact variant of the MP5.
Will fit inside briefcase designed for concealed carry, from which it can likewise fire due to trigger on the case's handle.
