Switzerland hasn't had a mass shooting since 2001. Yet they have one of the highest rates of gun ownership in the world - there are around 2 million privately owned for the population of just over 8 million. In a culture where guns are incredibly engrained, measures have been taken in order to keep gun violence under control, such as most men being taught how to use a gun through mandatory military service, and gun providers having to follow strict licensing procedures. In addition, Swiss laws are designed to prevent anyone who's violent or incompetent from owning a gun. The law also states that anyone who "expresses a violent or dangerous attitude" won't be permitted to own a gun. Gun owners also have to prove they can properly load, unload, and shoot their weapon and must pass a test to get a license.
