Please read and understand...
I just had a very close family member take the first 3 NRA approved training classes. She got to shoot 150 rounds and I was very happy with her shooting skills and targeting ability. What I didn't like to hear was some of the things her instructor was commenting on. I think she trust my skills and knowledge, but when you are paying someone big money to learn something and that instructor is "certified" I can understand her concern at our differing answers.
There are many instructors out there giving false info to students. Read the link above and see what I mean.
None of his opinions have any place in his class. I would truly prefer to be in a room full of armed people, then to have anyone leave one at home and truly need it.
I hope I keep my credibility with my close family member. Guys like this one need a talking to.
