Just my own experience hearing of NRA instructors from a few folks i retrained. Youll probably do a much better job of training them if your willing .Story time, get out the popcorn and adult beverages.
When I took my now ex-wife home from our first date her roommate was watching a movie starring Kurt Russell as the guy in Texas who climbed a tower and started shooting at one of the colleges. I can't remember the details, it was a true story, but one I hadn't heard at the time. At one point in the movie a cop is berating a gun store owner for selling the guy "that much ammo" (paraphrase).I I blurted out that I had 4 or 5 times that much on hand horrorfying her roommate.
2 or 3 dates later she wants me to take her shooting, because she now knows I am a gun guy. We go to the local indoor range and I load a magazine for my Browning Buckmark and give her some basic instruction, I stand close behind her while she shoots watching closely. While I am watching I am loading a mag for my 1911 long slide. She puts 10 shots in the 7 circle with the Browning first time out. She then turns around sets the Browning down grabs the 1911, I had inserted the mag but not closed the slide, she thumbs down the slide release, and puts 7 inside the 8 circle this time. Turns out her dad and brother are not gun guys persay, but they are serious hunters, and she had been taught the basics. One of the reasons she was a keeper, somewhere along the line she decided I wasn't a keeper though.
This brings me to my current dilemma, my brother and his wife have asked me to teach them to shoot. Neither one will become a "gun person". Sister in law is a former insurance salesman/adjuster, she is scared of everything that walks, talks, or digs holes. She will be the problem. Brother is a doctor, he wants to protect the family in an emergency. At this time they want get their concealed carry permits. I have a range here on the place. My basic plan is to conduct a basic familarization (revolver vs semi auto) and safety class, then urge them to take the NRA beginner course. followed by the carry course. I invite comments and Ideas. I do not want to pass on my bad habits, but want my brother to show up for the class prepared.
I am going to stress revolvers, because they will not practice as much as they should, also I am a revolver guy in general, but my edc is a S&W M&P Shield..
