[HD1200]

NO it doesn’t penetrate armor. The 5.7 bullet will when shot out of a 5.7 rifle with a casing, but not the handgun. Too low of velocity, just 2,200 lbs. or so. A high velocity 22 has 1,500 lbs. Can a 22 punch a round through armor? Nope.

The AP round can penetrate Class III body armor...that’s one of the things that made the gun a brief celebrity on the Brady Campaign list. The commercially available ammo won’t penetrate Class III, but it might penetrate I & II, don’t know for sure.

Had never seen or heard of the caliber before.

You can throw rocks if you want, and probably know more about ballistics than I. But I posted this to show that the reported caliber with a 20 round clip could explain the high number of rounds he got off.

And depending on the bullets and his accuracy the high kill rate.

I do not know why everyone is so argumentative on this.

I guess it best that I leave it alone.
