Or you just ban it completely for everything but hunting and regulate that strictly (ofc with exceptions for police and military). This is the way gun laws work in most European countries and most of them are indeed very save places to live in.
Your point here is a typical American one and just not any good. Guns in self defense rarely help anyone and do way more harm when random idiots who suddenly feel a need to kill someone finds themselfs already with a gun in their hand. Not to say that it’s impossible to get your hands on a gun in (for example) Sweden but the price and complications that ce with it do stop a lot of people from doing stupid things.
