The 12 hour course just teaches you the basics and the law. Even with that I don't think it does enough to help you out in a real life situation. Consequences of making a bad decision during critical times could mean life or death. Not knowing the law could mean time in prison. I think it should be a pre-requisite for a person to know the operations and different type of firearms before they go to class and class should mostly involve knowing the law inside and out and what to do lawfully in certain situation arises. Also there should be more time on the range with live firing drills where if you have to use a HG to defend your self, IE drawing out of the holster, shooting and moving to cover, clearing failures, reloading, etc. While we are on this topic, Advance Conceal Carry 1 and 2 from mofta is a great class to take that goes over all of that.
