Sometimes, you get out to the range and find yourself with a very excited student. All he wants to do is fill up the magazine and rapid fire like he has seen in the movies. I write "he" because, frankly, women don’t usually have this issue. It is up to you, the instructor, to re-focus your student and get him to focus on the fundamentals. As a new shooter, rapid firing 9mm rounds, he will be lucky to get shots on paper, let alone a respectable grouping. If allowed to continue, he will escalate, getting more hyper and shooting worse. In the end, he will be frustrated, and tired, from all the adrenaline. It will not have been a positive experience. That is not the goal.
You need to “interrupt the behavior cycle”. Yes, there is a term for it. As he is spinning up, you need to gently, but firmly, bring him back down. There are always different ways to do that, it depends on your personality and your student. When it happened with me, I had him clear and lay the gun on the table, step back out of the booth and take a couple deep breaths. Then, I circled my hands wide and brought them together in front of me while telling him he needed to center, like The Karate Kid. Once he quit laughing, he did, and the cycle was interrupted. We went back into the booth, I had him load 3 rounds in the magazine and fire them one at a time. He went from all over the cardboard to drilling the 3 inch sticker I had put on the paper. He was able to do this consistently, and after a couple reloads, I was comfortable letting him fill the magazine to capacity, and he calmly shot the sticker off the paper.
What could have been a miserable experience turned into a happy, high-fiving student who was smiling as he left the range with his completion certificate and his souvenir target with a nice tight grouping.
