5.7x28mm WEAPON SYSTEM
The 5.7x28mm weapon system is comprised of three components: the 5.7x28mm ammunition, the P90 Sub-machine gun, and the Five-seveN handguns. The 5.7x28mm SS190 ammunition has been designed to bridge the gap between the 9mm ammunition and the 5.56 x 45mm. The 9mm FMJ round will not penetrate modern body armor and the 5.56mm (.223 Rem.) rifle ammunition creates over-penetration concerns in a close combat situation or urban warfare. The SS190 has unique design, utilizing two metal inserts. The tip of the ogive has a steel penetrator followed by an aluminum core that is heavier than the forward tip. This causes the bullet to tumble in soft body tissue after 2 inches of penetration. This design virtually eliminates the risk of over penetration. This also creates a large wound cavity and quick incapacitation. The SS190 will perforate 48 layers of Kevlar up to 200 meters when fired from the P90 and achieve the same result up to 50 meters with the Five-seveN handgun. The 5.7 ammunition has only 60% of the recoil impulse of a 9mm. The muzzle velocity of the SS190 is 2,346fps when fired from the P90 and 2,133fps with the Five-seveN. Tracer, Sub Sonic, Training and Blank ammunition available. Ammunition is supplied in the U.S. by Olin.
It was being discussed (inappropriately) elsewhere that .22s are good for silencing guards, dogs, and various other Bond-like targets: given that this gun is much more accurate and powerful than a .22LR, do you think it will find its place in either military applications or perhaps a choice for CCW?It's always a good thing to be aware. There are real dangers out there faced by LEOs every day. That said, the article is a little over-the-top. The author refers to the FiveSeven loaded with SS190 ammo, which is not only armor-piercing, but also restricted to law enforcement and military only. No civilian can get their hands on it...FN won't even sell it to individual officers, only to departments on letterhead.
The civilian-legal ammo is SS192 hollowpoint ammmo, which lacks the steel core of the SS190 and is classified as non-AP ammo by the BATFE. It will still go through a level II vest, but only by virtue of its small size and high velocity, and much in the same way that any small HV pistol round will go through kevlar...like .22 Magnum, or 7.62x25, both of which have been available for decades.
I wouldn't be too concerned about the Five-SeveN. Those things are very expensive and rarer than hen's teeth, the civilian ammo is expensive and hard to find, and the unrestricted loads won't do anything that a .22 Magnum out of an AutoMag II won't do for a lot less money.
Now I am actually pondering selling my brand new Five-SeveN. It would make a swell little carry gun, as it is very lightweight and holds twenty rounds, but I'd rather not get pulled over by an officer who has that bulletin in the back of his head when he discovers that I have one of those things in my holster.
(Then again, he may just be a fellow gun guy, and ask to take a look at it.)
I agree that cheap and easy-to-find rifles make it unlikely this will be anything but a professionals' choice for killing cops, but what about the other applications?
