I don't know about UK, but I grew up in Poland. Grandpa had every kind of gun you can imagine. It's a lot easier to purchase a long gun there. I remember my father had to go through a process to obtain a pistol and license to carry. He was threatened by some business people. Probably Russia mobs (seriously... not even a joke).
We used to go hunt with grandpa a lot. He was born and raised German, so shooting things kind of came naturally to him
(too soon?)
