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.
That's only in the real world. The internet commando will always need a Glock 17 and at least 3 extra mags.
