I would highly suggest some training, not just shooting, but also the ethics and laws pertaining to packing heat. Better to know than to guess. Check out your local shooting ranges for classes.

I've been doing it for 16 years and have never had an issue. If you are prone to anger or very emotional, don't carry. If you are level headed and easygoing, still think about it.

Learn your weapon, know how to shoot it, and know how to clean it. Invest in a good holster.
