You can own guns in the UK, but few people do as there is no need. There is a shooting range no far from me, but it's simply not poplar here. I guess that why the US has approximately 160 times the gun death rate of the UK!
To be fair it's not difficult to get a firearms licence in the UK. That people (generally) don't show there are very few people who care about it enough to go through the faff to get one.
I'll be the judge of that, not you.
