>bear-resistant containerInteresting idea, but you should be using a bear bag, which should be hanging in a tree 50+ yards from your camp

Realistically, the revolver is something I'd bring if I was planning on doing a fishing trip in middle-of-nowhere Alaskan bear country. Otherwise, spray should be fine, if you know how to camp around bears, make enough noise to be known, use a bear bag, avoidance, etc.
