I thought this is an interesting read about using common sense in brown bear country in AK.
I lived in AK for about 17 years and never had an issue with brown/grizzly bears. Of course, I was often hunting big game when in bear country and had sufficient fire power in case of an incident. I also hunted them and believe me, it's unbelievable how fast they can move. If one isn't darn good with a pistol, not much use, IMO.
I also spent a bunch of time fishing some of the rivers and streams and never had a firearm with me (unless of course I was also hunting). I used situational awareness and would make enough noise when fishing with friends. Since it's SE AK you mention and mainly working in a saltwater environment, a stainless 870 with buckshot or slugs should work fine, with the caveat that the owner knows how to use it well!
Cameron, if he doesn't know or is unfamiliar with a pump shouldn't a double be the next choice?
