OTOH, your own reach is much more limited. You'd have a hard time stopping Abu Abdul from breaking into the cockpit when you are at the front of coach class. With the .45, you could do that, even I could do that, and I'm not that great a shot. Remember Abu doesn't care if you eventually kill him, you have to stop him cold. It's what the .45 ACP cartridge was designed to do, that is stop Muslim fanatics.
That's fine. I am not on the airplane. About a brazillion Federal officials are fixated on that one.
