You can forget the shotgun, here.
Pistols, too.
Your proper response to assailants with “bulletproof” apparal is standard military metal-cased ball. From a rifle. Armor-piercing is even better when you can find it.
Good ‘ol buckshot just won’t “cut it” as it were.
Just hit center mass and you’ll be fine.

5.56mm greenies slice through a vest like it was made from toilet paper.

I’ve heard that a CZ52 is a pistol that will shoot through any body armor.
