Hello all, please bear with me as I'm somewhat of a novice when it Comes to guns. I'm a pilot, and may be required to fly a small airplane to and from Alaska in a couple of months (this might become a regular trip, although I'm not too sure). There are plenty of lists online of things required (by alaskan / canadian law) and recommended to be onboard in case of an emergency situation. Most of these include a gun of some kind. A few people I've talked to said a 12 Ga shotgun is probably my best bet, as there is a variety of shot I could use (birdshot for small game, buckshot / slugs for defense). Does this make sense? What exactly should I get? From my limited research, it seem like a remmington 870 is a decent choice, as they're abundant, reliable, and inexpensive. I see there are probably 20 different versions listed on the website, what are the differences between all of these? Should I look into a rifle (if so, which one?) instead? A handgun is out of the question (I believe) because I'll obviously have to go through Canada to get there. Would all of you say a gun is necessary, period? As I said before, I'm a novice. I've shot several different thing, mostly handguns, but really don't know much about it. I'd plan on practicing with anything I bought, but maybe it's one of those things that if you're not pretty skilled it's more trouble than it's worth? Any other (constructive) advice I gan get is greatly appreciated. Thanks.
