In most European countries you have to store the firearm in a locked safe, often with the bolt removed or the weapon disassembled and - quite often - with the ammunition stored separately in another locked container/safe.
It’s a lot more “steps to take” to commit suicide than “take the weapon from your nightstand and shoot yourself”, given you have to unlock usually more than one safe/lockbox.
I assume that's not any of the concealed carry countries as that would completely defeat the point of having the gun. Definitely not the case where I live.
The countries allowing CC are - unfortunately - in the minority in Europe.
Among the ones that do allow CC, most of them that’s a special permit that seems to have an exception to the storage requirements for personal protection.
Personally I wish more of Europe would emulate the Czech Republic in this matter…
