If you have never owned or carried a firearm, then you need a real gun safety class. Then a CCW class, then tactical training after that. You are going to need to shoot 1000s of rounds before you carry.
I believe everyone should carry, after proper training. I grew up with firearms, had Uncle Sam give me lots of tactical training, and now carry everywhere its legal. I trained my wife and daughter on the basics then sent them to tactical training. We shoot at least once a month and enjoy it as a family.
Get comfortable, then get good, then be prepared to use it.
