Heck, when I took the class, there were only 3 rules.
1. Don't shoot the instructor. That's a definite no-no.
2. Don't shoot a classmate. That's also extremely frowned upon.
3. Don't shoot yourself.
Looking back upon those who took the class, I seriously doubt they carry their weapon now. They probably carried it a few times then decided it was more trouble than it's worth.
One young fellow was showing me his 9mm Hipoint. He lamented that he thought he was getting a 45 and asked if I thought he could take it back. I told him I doubted it. I hope he's doing ok.
BTW, I strongly resent having to take a state mandated class in order to exercise a Constitutional guarantee. I don't know at which point we allowed ourselves to think this is government's business, but we erred.
