Review the laws on the use of deadly force in your state periodically as well as where you can and can not carry a concealed handgun. And if you are traveling you need to be up to date on the laws where you are going to be traveling as well. I see many students in the Refresher and Renewal classes who have forgotten important details regarding the legal use of deadly force and where they can and can not carry their concealed weapon. You need to know this! The web site www.handgunlaw.us is an excellent resource for this. Visit it often.
