Switzerland often gets bandied about in these discussions, because people see gun ownership rates and ignore the subtleties. All adult males are required to own and keep a rifle at home (with some minor exceptions). There is no "gun culture" here, people in general are very unenthusiastic and see it as a burden.
In the last 20 years they have stopped giving ammunition to keep with your military rifle, exactly because they started having problems with shootings. Switzerland is the worst possible "example" of gun ownership reducing violent crime.
