Austria: relativly strict: you have to have a reason (hunting, self defense or sport). depending on the category of weapon a mental assessment could be necessary (not in case of hunting rifles only). automatic weapons, explosives and some other weapons are not legal to own privately. you have to securely store the weapon and need an extra permission for carrying - which is nigh unobtainable, even for active police. Transportation in a locked container and unloaded.

i use a very similar one, in german we say: everything that doesn’t pay rent gets thrown out

Same in Austria but passiv-aggressivly framed as a rhetoric question: “War dein Vater ein Glaserer?”
