The best person to introduce someone to the joy of guns: a professional firearms instructor. They can teach the newbie gun safety from the git-go, as well as proper stance, grip and trigger control. (Remember: it takes a thousand rounds to reprogram a bad habit.) An instructor will equip the new shooter with proper eye and ear protection, if only to avoid nasty lawsuits. The pro will show the newbie how to handle recoil. And they’ll maintain proper distance from the shooter—both psychologically and physically. Because anyone showing anyone how to shoot anything should remain objective, hyper-vigilant and stand so, should stand so, should stand so close to them. Otherwise, there’s a chance the shooter will point a loaded gun at someone, as they did in this [sensibly removed] video.
