What exactly do you mean by "gun safety"? I don't think you're talking about accidental or negligent discharges resulting in injury or death. Firearm enthusiast groups, firearms manufacturers and dealers have put significant effort in to educating the public about safe handling which has reduced unintended shootings by a large amount over the past 50 years or so. This would be a strange problem for someone not involved in the firearms industry directly to tackle. If you were to include suicide, which accounts for the majority of fatal gunshots, I submit that there doesn't appear to be much if any correlation between suicide rates and access to firearms internationally. I'd certainly try to keep a suicidal friend away from firearms, but it's just not that hard to find a quick and reliably way to end one's life. Suicide prevention probably shouldn't focus on methods of suicide. If you're talking about reducing gun crime, I actually do have an idea. Right now, very few people who fail NICS background checks are prosecuted, yet many of them have committed a felony by lying on the background check form they're required to fill out when buying a gun from a dealer. If it's due to criminal history, the police should show up to deliver the news about the failure in person - and arrest the buyer. If it's for mental health reasons, the person should be involuntarily detained for psychiatric evaluation. Obviously, the false-positive rate needs to be low for this to work.
