In the UKyou need to be a member of a club and after about 6 months you can get your firearms certificate.
Your family doctor will also be contacted to make sure you are not known to be unstable, drug addicted, etc.
Now, I was at Bisley shooting today and I was literally the only person shooting at the huge range - just because it was raining.
IMHO there are 3 main reasons why so few people shoot or collect firearms in the UK:
(1) In the first place, they aren't interested.
(2) In the second place, they can't be bothered with the [entirely achievable] paperwork / bureaucracy and the 6 months wait.
(3) In the third place, they weren't interested in the first place.
