5.7 x 28 mm Ammunition

 

It is a sad commentary on the time we live but the criminal element, which police are facing today, is more and more determined and resourceful.  They could be classified as professionals who carefully choose their targets, weapons, and protection, which as the Bank of America and other recent incidents prove often include personal body armor.

This is the reason why FN Herstal developed the 5.7 x 28 mm ammunition for the P90 submachine gun and the Five-seveN pistol.

The round will consistently penetrate 48 layers of Kevlar where all known 9 mm, .40 cal. and .45 cal. bullets will just bounce off.  The light weight, high velocity bullet will tumble on impact, ensuring reliable incapacitation without over-penetration.

Low recoil impulses makes follow-up shots quick and accurate because we know that in spite of all the hype written about new wonder bullets in the industry bullet placement is the single most important factor in ending a lethal confrontation.
