Heck, you can shoot a dryball out in your back yard. It only makes a loud POP.
That may be true, but I live in a suburban area and don't want to freak out my neighbors.
I just got a CCW. Funny, it has made me super concious of being lawful. Not that I wasn't before, but I don't even want to risk doing something that might get my right to carry taken away.
