Hi Slugs Away,
Even though my house is technically within the boundary of Anchorage City Limits, it is in a forest environment.
I have had a grizzly in my yard once, a wolf twice and black bear several times.
So, I keep handy a .375 H&H Mauser with open sights and 300 grain round nose softs in the magazine but, maintain an empty chamber until some greasy old bear or hungry wolf is made known to me, either by a neighbor's phone call or the rare occasions that my lazy dog barks the alarm for us.
It's not camping but large animal encounter / concerns are the same once you walk out of my house.
As for tent camping, such as during a wilderness fishing / hunting trip here in Alaska, I usually keep that .375 handy (and I have also used it to take both caribou as well as deer ,during hunting seasons here).
Regarding handguns, I am the clumsiest fly fisher in history so, I often get lazy about struggling with both fly rod and rifle simultaneously and leave the .375 in camp while wading around and flailing the water with fly line, etc.
My revolver for fly fishing activities is a S&W Model 629, in .44 Magnum with 4" barrel, carried in a chest harness/holster with Federal brand 300 grain "Cast Core" loads only.
In the two speed loader pouches of this harness, I carry two HKS brand speed loaders with the same ammunition in them.
I've never had to shoot a bear off me and hope to never have that experience, especially with the handgun.
Also regarding handguns for defense against aggressive animals (4 legged or 2 legged either one), I have recently examined the newest 10mm caliber Sig pistol.
I believe it is called the P220 10mm or something like that.
It retails for about $1300.US dollars here in Anchorage and seemed like it would be a real fine choice for those who prefer an auto-pistol over the revolver mechanism.
I like both designs and if I did not already have my excellent .44 as mentioned, I could easily be talked into this relatively new Sig 10mm instead - it is a real dandy IMO.
Well anyway, no matter what firearm you carry, practice often with it and get comfortable with the idea that someday, probably when you least expect it, you or a loved one, (perhaps even some unknown innocent victim) will be suddenly in need of you and your weapon.
Stay on that front sight,
Velo Dog.
