I had a close older relative who owned shotguns legally for rabbit hunting
[..and probably a bit of old fashioned country man poaching...???]

He kept them at home in an approved gun safe..

Unfortunately in a state of grief and whatever else was going on in his mind,
he took one gun, went out into a public place, made a bit of a shouty 'sorry for himself' scene, then comitted suicide with it..

In the UK that is still an exception, and possible justification for even stricter gun control...???

But sad as that famuily loss is, that would not deter me
if I was seriously determined to collect vintage guns as a responsible hobby
[in the same way that I collected cameras and guitars].

My relative could just as easily have gone out on a suicidal rampage in his car...

On balance, despite obvious problems, It's relatively safer and saner on our side of the Atlantic...
