I know of darn few CC guns that I'd put up against any rifle. Encountering a terrorist with an AK or AR is highly unlikely although there's no doubt that it COULD happen. By far the most likely need for a gun is a mugger. Shoving a 380 in his face or a bullet in his gut will usually back him off and let you make a getaway. It's not a game of firepower. It's one of escape. You just need to make him think he's going to die if he doesn't back off.
