I'm not even a certified instructor, but I let a middle aged woman who I think had never fired a gun before, come to my place ( private property) and showed her 1 on 1 the basics. It was just me and her- and some poultry wandering around LOL. I showed her the guns, magazines, and ammo first, and how to check if the guns are loaded or unloaded. I showed her how they are loaded w/out actually loading, and how the firing mechanisms work ( striker fired pistols and dbl action revolver w/hammer). I showed her how to put rounds in a mag and in a revolver chamber, and how to remove them by hand. She already knew the basic safety rules and I watched her as she handled the unloaded guns and I could see it. Lastly I went over holsters and carry methods, CC and OC.
We then went outside to the makeshift range. I set up 2 targets at 15 feet, and 1 at what I think was 25 feet. I started her on the .22 revolver. She went right for cocking the hammer back for every shot LOL. Much easier with the minimal pull. I had to correct her grip with both revolver and semi autos. Once she had things set up right, she was doing quite well. She picked up quickly on figuring out the sight picture of each gun. Once she figured out the .22 and was making lots of central hits, we went to the 9mm. She proceeded to make 1 big hole in the center of 1 of the 15 foot targets, with the XD9 sc. Lastly I let her try the XD40 4", and while it had more recoil, she figured the sight picture out pretty fast. I also noted she was not doing any anticipatory flinching, as she would fire the last round and the slide would lock back, but she hadn't noticed and tried another shot- she did it more than once and I saw zero flinching. I did of course tell her she needs to watch for the slide locking back LOL.
At the end I told her that she can work on increasing distance in later sessions, but that most self defense scenes play out at 15 feet and less. That is her primary purpose for when she does buy a handgun and gets her PA LTCF. She was VERY happy she got 1on 1 instruction with another woman, and that she had ALOT of fun. All she had to pay me for was ammo.
