50 Rounds of 5.7x28 mm Ammo by FN Herstal - 27gr JHP

Starting as a “From Scratch” buildout of a highly engineered cartridge meant to replace the 9mm for specific law enforcement and other highly specialized purposes, the 5.7x28mm turned out to be one of the more interesting development stories in the modern era in ammunition. The lethality and potential uses for the round were among the reasons it has taken off in the law enforcement arena. It is represented in the engineering and ballistics world as a truly remarkable accomplishment because of the achievements made along the way.

The high capacity potential (it weighs less than half of a 9mm round) and the exceptional velocity of the tiny round as well as the tumbling of the projectile after impact, made it something of a legendary talking point for skeptics and proponents alike.

With the ongoing press about the cartridge and the lower recoil (30% less than a 9mm), civilian shooters managed to overcome the high price tag caused by relative lack of production volume to continue to adopt this unique round for use in a handful of different use cases.

The secret service adopted the cartridge and it’s related FN produced firearms as duty weapons and solidified the cartridge and the reasons it was produced in history.

This civilian lead free version offers a copper clad aluminum projectile at 28 grains.
