FN 5.7 Pistol-In 1935, the FN-made Browning Hi Power was revolutionary. The market quickly adopted this high-capacity 9mm pistol accordingly, and it has since been fielded by over 100 countries.
FN most recent contribution to the evolution of the gun is called the five to seven years. This 20-round pistol fires a 5.7mm bullet that defeat most body armor in military service around the world today. In essence, the Five-seven represents a great leap forward in the gun suitablity for commitments by providing the kind of performance that were previously confined to rifles or carbines. Elements of this action:
High hit probability: The Five-seveN’s extremely low recoil impulse results in virtually no muzzle climb, thereby facilitating fast and controllable follow-up shots.
Light and ergonomic: Weighing 30% less than most 9mm pistols, the smoothly-contoured Five-seveN is comfortable to carry and quick to deploy.
Fully safe: Due to its double-action firing mechanism, the Five-seveN® offers no inherent risk of accidental discharge during transportation. Furthermore, all of its safety devices are automatically reengaged following each firing cycle.
The Five-seveN® fires the SS190 5.7×28mm ball round. This projectile will perforate any individual protection on today’s battlefield including the PASGT kevlar helmet, 48 layers of kevlar body armor and the CRISAT target (titanium and kevlar). The SS190’s conventional design allows it to be manufactured on existing production lines, and its lead-free composition eliminates range contamination.
