The History of 5.7X28 Ammunition.
In 1991, the Belgian company FN Herstal released the FN 5.7x28mm cartridge after NATO requested a replacement for the 9x19mm cartridge. Since Kevlar body armor was effective against the 9mm, developing a cartridge that would overcome it became a priority. This objective was achieved by the 5.7x28mm by penetrating vests of level IIIA without any difficulty at 200 meters. The 5.7x28mm cartridge not only pierces armor and has a high velocity, but the bullet’s shape reduces the chances of ricochet, which reduces collateral damage. A second benefit of this cartridge is that the majority of its kinetic energy has been expended by 400 meters – a benefit since it was developed for use in handguns and submachine guns, which have effective ranges of less than 200 meters.

There are several advantages to the 5.7×28 cartridge due to its smaller size. Since it weighs half as much as the 9mm, a solider can carry twice as much ammunition. Furthermore, the magazine capacity of firearms chambered for this cartridge has been significantly increased. The FN Five-Seven boasts a flush-fit magazine holding 20 rounds, and the FN P90 submachine gun features a detachable magazine holding 50 rounds.
