In a discussion once with a locksmith he thought having very well hidden secured place was in general better than a super safe. But if they know you have it, then eventually it will be found if there is time or if they have you and four family to persuade that is another way of getting it.
Advertising an extensive gun collection or anything of great value is not wise.
I would assume that most but all of us on this forum have a pretty good gun collection.... So better get off of here!!!
