Not really, but I still try my best. I invite people to the range, offer to take them to IDPA or USPSA matches, give them info about instructors and other classes, etc...I even have a range bag, gun and gear set aside that I let people use. I can't tell you how many people, (including Active Duty Spec Ops) who do not even own a firearm! Just keep trying.
Something that does convince some people to get more training is AFTER they've been involved in a dangerous situation.
