At first, it used straight magazines much like the UMP-45, but adopted the standard curved magazines in 1977.

Owing to the success of the HK G3, the MP5 (initially known as the HK54) began its development in 1964, and eventually was adopted by the German Federal Police, special forces, and border guards, where it got its designation as the MP5. The MP5, or Maschinenpistole 5, is an SMG chambered for the 9x19mm Parabellum round, developed by Heckler & Koch in the 1960s. It's viable on Hard, and below, and if you get it early enough, its even viable on Nightmare, though MP40 might actually be in the superior pack to purchase, as there are stronger weapons when bridging between Revolver/Kar-98k/Crossbow as well as AA-12/USAS-12. Its only available to those who have purchased the SWAT Pack, (499 Robux.) It’s a nice, standard weapon that’s simple yet effective to use on early waves.

You can sort of think of it as an MP40 that shoots faster, but deals less damage. The MP5 Is a cheap, yet effective Sub-machine Gun made by Heckler and Koch.
