Defense

I'm looking for a fairly portable shotgun that will fit nicely into a quad box or lightweight to carry, that will only be used for unexpected bear occurrences and is capable of firing slug or 00. I have been looking at the 12ga defenders with the aftermarket foldable stocks, but am having mixed feelings cause they are rifled for slugs. Does anyone have a recommendation or insight on whats a good model for the price. Or whats better slug only?

Thanks


Jason
