Is The 5.7x28mm Round Adequate For Personal Defense?

Let’s make the argument that 5.7 is, just for fun and for the purposes of this article, as suitable for personal defense as 9mm.
If we wanted to bolster a case that 5.7 is a viable defense round, we could start with this punny line: The 5.7 uses a bottlenecked case, like the .357 SIG, which is theoretically supposed to increase feed reliability. Second, 30% lower felt recoil is going to translate into better accuracy, better shot placement, and faster follow up shots. Third, the 5.7 can squeeze 20 or (as Hop learned in the video above) 21 rounds into a full-size frame for more capacity than 9mm. Fourth, the ability to defeat body armor is a plus – according to FN, the SS190 cartridge type can defeat two stacked Level II vests at 50 yards. The round will also go through a vest and remain effective – allegedly penetrating 11 inches into ballistic gel after punching through a Kevlar vest. Fifth, we have the advantage of the increased range we discussed above, albeit this is of limited use for the reasons noted.

Moving away from gel and paper, there’s empirical evidence suggesting that the 5.7 is effective. Over forty countries have adopted the 5.7, including the USA at a federal and state level, most notably, the US Secret Service. According to an article from the Dallas News, the Five-seveN is sought after by Mexican drug cartels for its effectiveness, and FN’s pistol can fetch $5,000 on the black market because of its performance, especially against armored targets. And as macabre as it might be, I reluctantly note for purposes of this discussion (and because someone was definitely going to say something about it in the comments anyways if I didn’t) that the 5.7 round was used in the most deadly American on-base shooting of all time, killing 13 and wounding over 30 when an Army major-turned-terrorist used the Five-seveN in an attack against fellow soldiers.
I’ve addressed this before. I would carry the round for personal defense.
And if I’m not mistaken, his conviction on 13 counts of premeditated murder was short one. One victim was pregnant.
