We have 3 rifles at home but none of my family members has ever used them. They are locked up nice and safe. In normal life, I think guns aren't necessary but considering the apocalypse I feel quite safe thinking about my rifles at home...
I am from Italy and in my country it's very hard to get a gun. You have to fulfill several requirements to even get one. I am not much of a fan but I would use one if I need to.
