I was fortunate enough to take a couple of younger relatives to their first range experience. We held an informal class with them at home before we went to the range. They commented on how much helpful it was to do that.
One thing which stood out for me, was noticing some of their habits they need to unlearn, like having a conversation with a firearm in their hand, especially when some people naturally talk with their hands or use their hands a lot when they talk.
We had to practice, no, first put the gun down in a safe direction, unloaded, then you talk, and working on conditioning that.
While we are kind of on the topic, if it’s range time for the brand new shooter, I think it’s good practice to load the firearm for them the first time (on the line muzzle downrange entirely of course), and give them an empty gun or snap cap for the first trigger pull to watch for the flinch, repeat until flinch is gone. Then, load one round into the gun, so that no matter where the muzzle points after the recoil, and where their finger is, it won’t fire again. Optionally put a dummy round/snap cap behind that first round that they again do not know about, thinking it’s still live, to see how they handle it, and see if that flinch came back for the second shot.
Transition this into a slow fire for accuracy ball and dummy anti-flinching + follow through drill.
Definitely do not give a brand new shooter a semi auto pistol with multiple rounds available for their first go.
