I carry pretty much all the time. I learned how to handle a weapon in the military, but even that should not replace a formal gun handling course. I know it isnt right to force a 3 day course or anything, but a basic gun handling course is a must.

Think of it like a motorcycle safety course. Most people that I know that ride and have taken the course have said they learned something. Even the ones that have been riding for 10 years or more said they learned something.
