Finland have similar number of weapons, Swiss is not that distant, the issue are not weapons but society: any ruling class in pseudo-democracies (i.e. our formal but not substantial democracies) need something to pasture people avoiding revolts, the USA have built a false-free and competing ideology that's essentially push people to blame themself for their suffering and that's easily push fragile people toward nihilism, Swiss is not that different, only it's able to test people (mandatory conscription between 18 and 28 years of age, one paid month per year) and to offer not so bad overall living conditions. Other dictatorships choose different ways to pasture people.
The actual crusade against weapons, and I say that as an European left-wing Citizen is just because unrest was predicted due to neoliberal ruling [1] and they dislike the idea of an armed population that a day might shoot against them. In Italy fascists have done the same erasing military conscription NOT because it produce bad results (it do, but that's another story) but because they choose to even remove such hyper-basic training to form generations who shoot every days in videogames and in reality they'll probably follow what they have seen in movies, like run to the root trying "to escape", lock themselves in bathrooms, protect themselves with sofa or fridge door etc and I'm pretty sure most movies have done such absurd choices exactly to mentally push people toward such absurd behaviors.
Consider a thing: if you are satisfied you do not want war nor violence. If you are not your dissatisfaction might be weaponized to push you do things you do not want (including hard work, war etc) for the sake of the élite of the moment, if you are pushed toward illegality is even better: they can let you go and if needed trap you with legit reasons. That's how our societies are ruled and our subjects, not Citizens, allow that.
Weapons are common in USA just because they support the infinite-war economic model of USA rulers, but people need to be kept in a sorry state to obey, that's is.
