5.7x28mm is a type of ammunition for firearms. In real life, this cartridge is considered to be part of the Personal Defense Weapon category, a nebulous category of small, high-velocity cartridges intended for compact firearms. Their primary purpose is to defeat armor; therefore, this caliber is classified in the game as a (R)ifle caliber, in order for it to have access to rifle-only projectile types and perform the way a PDW cartridge is intended.
In real life, this cartridge was originally designed for the FN Herstal P90 personal defense weapon. This was arguably the first purpose-built PDW. It entered in direct competition with HK's MP7 and their own PDW cartridge, the 4.6x30mm.
5.7x28mm is pronounced five point seven by twenty-eight millimeters.
This caliber may also be referred to as 5.7x28mm FN, after FN Herstal.
There are 5 base weapons chambered in this caliber.
