FN FiveseveN

Designed as a companion piece to the FN P90 submachine gun, the Fiveseven is chambered in 5.7x28mm. This caliber moves a .22-caliber bullet out of the barrel at 2100 feet per second, offering rifle velocity out of a pistol. This caliber was created by FN for the new NATO PDW (Personal Defense Weapon) concept, a design specification being the ability to punch through NATO standard body armor at 150 meters.
The FiveseveN is very lightweight, has very little recoil, and holds twenty rounds in the magazine. It represents a radical new approach to personal defense weapons, and the established gun writers out there have split opinions on the 5.7x28 system. Some deride it as worthless, claiming that the 5.7x28 has the terminal ballistics of a .22 Magnum at best, and some claim the cartridge to be the best thing since the invention of the metallic cartridge.
As in all things, opinions are worth exactly what you pay for them. In the end, the street performance of the 5.7x28 will be the final word on the issue, and so far, the round has acquitted itself well. During the Japanese embassy crisis in Peru, several terrorists were eliminated through their Level III body armor, including the ring leader, who expired after a single round to the chest. Several SWAT shootings with the round have all resulted in one-shot stops. It seems that the 5.7x28 largely lives up to FN's claims.
I like this pistol because it combines low recoil and high capacity with excellent barrier and terminal performance, all in a lightweight and corrosion-resistant package. It's a whole new and interesting approach to personal weaponry, and as such deserves merit for sheer ingenuity. "
