I believe that the Brady bunch is using half truths to "get something done". If I'm not mistaken, the 5.7 round was made specifically for piercing soft body armor. Of course, you would have to have the ammo with the steel penetrators. As far as the weapon itself, its an unusual gun to say the least: mostly plastic, saftey's in an usual but innovative place and it's easy to shoot. I've thought about giving one to my girlfriend as personal protection piece.
