edam "My BIL is ex-army but doesn't keep a gun, although he does borrow one when he goes rabbiting."
A gun, a rifle, or (more likely) an air rifle.
World of difference between them, where and when they can be used, and need (or not) of any licence and gun cabinet.
While I've no collection or wish for guns (that need a licence), I have had 2 air pistols and an air rifle, and it has been a hobby for 35 years.
Can understand the fact so many are anti-gun, but as indicated, it does depend on regulations and mentality of the owners.
That Swiss example is perfect, because households with a gun is in the top 90s per cent wise, even if (after Army service/training) 80+ % make no/little use of their gun, even for target practice.
Some people like guns, just for the 'escapist' element, like driving fast cars or motorbikes.
Nevada scrapped their speed limit and made it "suitable for the weather conditions" so people can rent fast cars and go full pelt on the highways if they want. Other people in the US go out and use big guns, just for the hell of it. I know there are videos of them, it's just fun, but that's a part of the problem with the US because for some it's fun, for others they get used maliciously.
While personally I am not especially craving an opportunity of firing a machine gun, given the factors that would need to be overcome (1, getting passport, 2, finding somewhere that would turn a blind eye to me not being a US citizen, and 3, not having a licence in the UK, let alone USA)...
even at 50yo, just as I'd be happy to spend a day at Alton Towers, I'd be very happy to spend a day paintballing (again)...
Maybe that's just a 'male' thing, or maybe an 'escapist' one, doing something out of the ordinary (esp as I don't drive, the funfair rides are all the more o-o-t-o from day to day on the train, bus, or on foot, to go anywhere).
