Ah, yes, that's true. But, it's harder to incapacitate unless you're really good with it. And, while it's definitely very intimidating, I think it would often be overkill in most situations.

Plus, it's a tougher sell when/if the cops come..."officer I was just defending myself" is a lot easier to sell when you beat a guy up with your hands rather than shoot him. There are a whole host of legal problems that automatically get raised when you draw a gun on someone, I think. Gotta make sure you're skilled, as well, or you're gonna end up blowing a hole in yourself, a friend, or an innocent. And your feet/hands don't normally need to be licensed (unless you're chuck norris).

Etc. etc. etc.
