How does it compare to the keltec .380 or 9mm? I haven't seen/held/shot the ruger yet, but it looks like it would be a good gun for what it was designed to do. It wouldn't be the gun kept by me bed, but it looks like a nice ccw. Is .380 enough to stop? I wouldn't want to be shot with it, but i'm not a crackhead looking to carjack you either.
