I carry a Glock 30 SF .45 ACP with Hornady Crtical Defense Rounds.
Obviously carrying armor defeating rounds is a bad idea. Hit a un amored bad guy and two poeple behind them would fall.
Get hit with a .45 ACP Hornady Hollow Point round and even wearing armor it would be like getting hit with a mallet. A BIG MALLET.
Ribs would break, organs could rupture, and the BG would indeed go down.
You might have to pop him 4-5 times but at that point he's disarmable and out of the fight.
