Some awesome points brought up gentlemen. I appreciate all the discussion.
This weapon is going to be used as a back-up and off duty weapon. I plan on carrying it in an ankle holster. The cost difference between the Taurus and S&W is negligible. Smith offers a LEO discount which brings the price into the same neighborhood as the Taurus. FWIW, I would trust my life to either company. In fact, my bear gun is a Taurus, so I guess I am already putting my life in their hands.
A mention of practicing with whatever tool you chose, while a wise statement, goes without saying. As far as a shooting situation is concerned, I fully believe that if you ever find yourself in a situation where you have attacked another human being, you just need to know that you will be getting sued. It doesn't matter if it is self-defense, if it is a part of your job, or if you are robbing a bank. YOU WILL GET SUED.
