If you want to learn how to shoot, don’t just go to a CC class. Go to a school that will teach how to shoot.
I would recommend Front Sight:
https://www.frontsight.com/
I would also recommend Thunder Ranch:’
https://thunderranchinc.com/
Both of them will teach you how to shoot and shoot well. I’m figuring out when I’m headed to Front Sight for their 4 day defensive handgun course.
