I started carrying a side arm 40 years ago when I use to go on annual backpacking/trout fishing trips in the Bear Tooth Montana Wilderness. The gun then was a Ruger Redhawk 44mag 7.5 inch barrel, loaded with 300 grain custom hunting loads. The gun was really too big and heavy for backpacking but I wanted something for grizzly. I wouldn’t really want to try to take down a griz with it but it was the best I could do. For smallEr black bear a 44mag is considered marginal.For a griz don’t want to find out.
Then I got a short barrel S&W 44mag mountain gun. That kicked like a mule so I so I quickly sold it. Now I carry. Taurus Tracker 4 inch barrel, in stainless which is ported so it reduces “felt” recoil.
Im a wheel gun guy, although I have a number of autos. When I’m in the wilderness I don’t want to deal with a safety, or with clips or anything else. I want a simple revolver I can just draw and fire. And I like my revolvers in stainless. Sometimes I carry a 357 mag which I feel the most comfortable with of all the handguns I own. My recommendation in California is a 44mag in stainless.
The odds of ever having to use your gun in the wilderness for protection from a wild animal is minuscule, probably close to zero. Even knowing this I still carry. It’s a habit. I carry both for 4 legged animals and for the most dangerous 2 legged lowlifes. There’s a lot of drug addled lowlifes wandering around. I’ve experienced 2 occassions in the wilderness where packing a gun saved my ass.
So carry a gun you feel comfortable with, and with a large enough caliber that it’ll take down the biggest thing you may run into.
