5.7 NATO for Self Defense?

Designed by FN as a caliber replacement for 9mm pistols and submachine guns in the 1980s, the 5.7x28mm was only recently adopted as a NATO standard. But is it any good?

While I’ll save the history of the cartridge for another day, the 5.7 was first marketed by FN in the early 1990s in its P90/S PDW/carbine and Five-seveN pistol. Since then, those guns have been adopted with military and police forces in more than 40 countries and sold widely on the commercial market. This undoubtedly led to its recent NATO standardization— along with its competitor, the Heckler & Koch -developed 4.6x30mm.

However, as the only gun available for the 4.6 NATO is the HK MP7, which is unobtainable on the U.S. consumer market, the 5.7 NATO is the default PDW player today.

The thing is, ammo selection can be everything.
