The biggest thing is take what you are told over the internet with a grain of salt till you personally verify it as truth.

1. Get very familiar with the laws in your state and others you may visit in the near future.
2. Get professional instruction on handgun defense for the concealed carrier.
3. Practice your technique and refresh your memory of local law.
Done.
In addition get familiar with case law in your area. In NM by the law deadly force is justifiable to defend property, or stop an unlawful act. I shoot and kill a kid steeling my lawnmower I bet I would go to prison. Read the NM law below and I bet you will see quite a few that would not pass muster in a court of law. In the end you have to decide what you are willing to shoot for. Also all the ramifications. As an example You are in a convenience store a bad guy has a gun on the clerk at the register. You shoot and the bad guy pulls the trigger in reflex killing the clerk. Yes it was his fault, yes you will second guess yourself the rest of your life.
