I'll outline how our group of instructors teach beginners, and that might give you some ideas.
I'm with a group of instructors putting on a monthly Basic Handgun class (originally it was an NRA Basic Handgun class -- our class hasn't changed but the NRA class has). We're older guys, most of us retired or close to it. We've all done a fair bit of shooting and training -- multiple classes at Gunsite, classes with a number of instructors like Massad Ayoob or Louis Awerbuck, USPSA or IDPA competition, NRA instructor certifications, and three are POST certified. Our training group is organized as a 501(c)(3) corporation. We're all volunteers, and none of use receive any compensation (except the company buys us dinner after the class where we do a debriefing). Our class fees are set to just cover our expenses and operating costs. We supply everything -- guns, ammunition, eye and ear protection, a book on California gun laws, etc.
Probably 80% to 90% of our students had never touched a real gun before. Our class enrollment runs roughly 30% female. We have students of all ages from early 20s to folks 70+. We've had entire families attend together.
Most of our student show varying levels of anxiety at handling real guns. We try to address this by bringing them through the course material in a step-by-step, measured and supportive way. We limit class size to 10 students, and will have at least five or six instructors at each class. The class runs about ten hours, but we try to provide adequate breaks. Periodically we discuss breaking the class up into two days; but since we often have students travel from some distance doing so might be a greater hardship.
In addition to the core lectures, the first of which is on safety, we do a lot of "hands-on" work with the students. The students handle a variety of revolvers and semi-autos under direct supervision, one-on-one, of an instructor. They use dummy rounds to load and unload the guns, dry fire and generally learn how things work and feel, and they get continual safety reinforcement.
These initial hands-on exercises help students get familiar with handling a gun and lay a foundation for safe gun handling habits. For beginners handling guns for the first time is pretty awkward. Guns feel strange in the their hands. Many are surprised by how heavy they are. They have no sense of how much or how little force is needed to operate the various "do-dads." The students begin to realize that although guns can be dangerous they can learn how to handle them safely and that safety is in their hands.
In preparation for live fire we put on a lecture and demonstration about how to actually shoot (grip, stance, sight alignment, trigger press, surprise break, focus on the front sight, and eye dominance). I usually do this one, and I like to use an airsoft gun fitted with a Crimson Trace laser grip to illustrate a controlled trigger press compared with jerking the trigger. We then work one-on-one with students on grip and stance using "blue" inert training guns.
Before going to live fire with .22s, the students shoot airsoft (the quality type) in the classroom so they can get a feel for sight alignment and trigger control (and reset) without the noise and intimidation factor (for beginners) of firing real ammunition.
After the students fire 25 rounds of .22 (working one-on-one with an instructor), we put out a variety of guns from 9mm to .44 Magnum so the students can get the experience of firing (a few rounds) the larger calibers. Shooting the centerfire guns is at each student's option. Most fire them all, but some choose not to.
During the live fire exercises it's not uncommon for a student to shoot 2 to 3 inch groups at seven yards with even the heavy calibers. A few months ago, a petite young woman who had never fired any type of gun before out shot everyone, including her husband, with the .44 Magnum -- putting three rounds into about an inch at 7 yards.
Going through our process most students shed a good deal of their initial anxiety. Some remain anxious to a degree but still manage to master their anxiety and perform well. In the last several years only one or two (out of perhaps a couple of hundred) could not complete the class.
Some time ago got an email from a student. She is a very petite Asian woman who is a PhD candidate in statistics at Stanford. She wrote:
Dear BayProfs,
Just wanted to say I had a great time at the Basic Pistol class this weekend. The class was very thoughtfully organized; it was very helpful to progress from watching the instructors, to doing the hands-on practice, to doing the real deal. I really appreciate how patient you all were in answering our questions and giving us feedback. So thanks a lot! I will try to send some of my friends your way, assuming I can convince them not to be scared of guns....
