One of the design intents for the standard 5.7×28mm cartridge type, the
SS190, was that it have the ability to penetrate
Kevlar protective vests—such as the NATO
CRISAT vest—that will stop conventional pistol bullets.[SUP]
[23][/SUP] Fired from the P90, the 5.7×28mm SS190 has a muzzle velocity of roughly 716 m/s (2,350 ft/s) and is capable of penetrating the CRISAT vest at a range of 200 m (219 yd), or a
Level IIIA Kevlar vest at the same range.[SUP]
