Switzerland and Australia are two countries we could learn a lot from in terms of reducing gun violence.
Switzerland has over 2 million guns (about .25 guns for every citizen) and guns are very important to them culturally (they have a large shooting contest for 13-18 year olds each year, and see gun ownership as a patriotic way to guard against potential invasions) but hasn't had a mass shooting since 2001 and often have less than 50 gun related homicides per year in a country with over 8 million people.
Specific laws that reduce gun violence in Switzerland include:
1) Gun sellers follow strict licesning procedures : Gun permits are doled out locally and they keep a log of everyone who owns a gun in their region in what they call a "canton." Cantonal police don't take their duty doling out gun licenses lightly. They might consult a psychiatrist or talk with authorities in other cantons where a prospective gun buyer has lived to vet the person.
2) Violent people or those with substance abuse issues can't have guns: People who've been convicted of a crime or have an alcohol or drug addiction aren't allowed to buy guns in Switzerland.
Those who "expresses a violent or dangerous attitude" also can't own a gun.
Gun owners who want to carry their weapon for "defensive purposes" also have to prove they can properly load, unload, and shoot their weapon and must pass a test to get a license.
3) The Swiss banned the use of automatic weapons, silencers, laser sights, and heavy machine guns.

Australia had a mass shooting in Tasmania in 1996 in which 35 people died.
The Australian Government, then led be a Conservative named John Howard pushed through strict gun laws 12 days later.
The laws:
1) Banned semi-automatic and pump-action shotguns and rifles from civilian possession.
2) Forced people to provide a legitimate reason to own a gun, and to wait 28 days to buy a firearm.
3) Had a massive mandatory buyback of guns, resulting in the confiscation and destruction of about 700,000 guns reducing gun-owning households by half.
Australia has had only 1 mass shooting since 1996, and gun violence has been reduced by over half.
