It rubs off on any new shooters who are coached by older shooters who coach them courteously and effectively. When I am "Coaching" new shooters I give them the important stuff right away. Firearm safety rules are paramount and always immediately addressed or corrected. Then we work on proper stance, grip, sight picture and trigger press. If you help new shooters get on target from the jump they will be much more enthusiastic about shooting. It's simply much more fun when you actually hit your target. One thing I stress A LOT is trigger discipline. It's especially important with guns like the Q5 match or the VP9 or a 1911. It's very easy for a new shooter to take a shot, then look back at their coach or somewhere other than the target while their finger is still perched on that light trigger. I think it's much more likely to accidentally fire another round like that then it is for them to screw up and point the gun at someone on purpose.
It takes some thought and patience to properly teach new shooters, but it's time well spent. I'm going to be taking my sister and my niece out for a day at the range soon. We will spend a little time with semi auto pistols, revolvers, shotguns and ARs. My niece is about to graduate with a BA in forensic science and will be interning for the FBI this summer. Presumably her goal is to work for the FBI. I would like nothing more than for her to go to her first range session with her FBI instructors shooting better than they do.
