Technically, the chambering we're discussing today is called "5.7x28mm," but most people in the gun community tend to abbreviate it simply as "5.7." As we've discussed here at NRA Family before, there are two basic paradigms for defensive ammunition: "small and fast" versus "big and slow."
The 5.7 round falls into the latter category, with blistering muzzle velocities and a lighter projectile than its next-closest caliber, the 9mm. But is it sufficient for self-defense? What are the upsides and downsides of this little round originally developed for NATO?
In this 60-second discussion, Shooting Illustrated's Kevin Creighton discusses how long the round has been around, as well as why it hasn't been more widely adopted by American gun owners before now. He also talks about the firearms available in 5.7, and how they can be part of your concealed-carry and self-defense strategy.
