European here, from Slovenia.

I have never even seen or heard a gun since moving to the city.

There has been a single shooting in recent years that I can remember in my city, with one death. It was targeted, though - not a mass shooting.

A factor might also be that we don't make a big deal out of crimes and don't have every single news outlet report on every single detail of it for a week straight. I just Googled that shooting and we don't know who perpetrated it, who died and what the motive was.
