I probably will be fishing/hunting mostly by myself as I don’t know anyone in AK at this time.
I think this is why it seems like only the tourists get eaten by bears.
As a general rule, don't do anything on your own here. As kids, we didn't go deep into the woods without a group of four. More people means more noise and fewer bear encounters. Good woodscraft will save you more often than a gun.
RalphS has it right. In Palmer, the .44 Magnum is probably sufficient, if loaded with the right cartridges (everybody I know uses the Buffalo Bore stuff). It's typically the coastal brownies that require a Howitzer to take them down. I carry a .357 Magnum Ruger Blackhawk loaded with either Buffalo Bore or Double Tap hardcast rounds. I don't feel undergunned, because I always hike with at least two guys with .44's and a guy with bear spray.
