300BLK in a 9-in AR style pistol will hit at 1100 ft-lbs (supersonic Barnes Tac-TX) which is three times what 9-mm will hit at. Plus you have AR manual of arms-controls, and with an innovative design (Brownells AR180, MCX) that removes the receiver extension, a very small package.

That's not what they wanted. They already have plenty of 9mm to use. They are not looking to kill a bunch of folks, just get the VIPs to safety.
