Great story! (Sarcasm)
For those of us who know a thing about guns, what was the caliber? I didn’t know they made handguns that would fire rifle calibers.
The penetration for handguns is in the ammo not the machine itself.

batfe doesn’t seem too worried about the FiveSeven or it’s ammo.
5.7 mm, which is why it is called the Five-Seven.
It was the 5.7x28mm. Basically a .22 magnum. Comparing it to a rifle round is laughable.
With any round you have a set amount of energy propelling the bullet, and you can choose lighter, faster bullets or heavier, slower ones. The anti-rights crowd jumps on the velocity (high relative to pistols, nothing compared to rifles) and completely ignores the tiny round.
The 5.7 has energy levels in the 300 ft-lb range. By comparison:
- Old police .38 revolvers are around 250 ft-lbs.
- The smallest round considered viable for self defense, the 9mm, has around 400 ft-lbs.
- The other two predominant defense calibers, the .40 and .45, have around 500 ft-lbs.
- The .357 Magnum and .44 Magnum revolvers pack about 750 and 1000 ft-lbs respectively.
- The “intermediate” cartridges in the AK and AR that the media love to vilify have around 1300 ft-lbs.
- Actual rifle cartridges, like your boring old .308 or .30-06 deer rifle, fall around 3000 ft-lbs.
There’s nothing “armor piercing” about it. It will go through a vest, the same way that any rifle, most magnum revolvers, and a variety of pistols will, because vests are designed for light pistol rounds. The fabric just can’t handle that much energy.
5.7mm (.224")
You can either look at it as a lower powered reduced case 5.56mm NATO, or a centerfire analog of the .22 Winchester Magnum Rimfire
