If you want a .357 Magnum, then go for it, but I'm gonna tell you right now: 9mm can quickly kill a black bear, so feral hogs and snakes aren't any problem for something like a 9mm, .40 S&W, .45 ACP, etc.
If you think anything smaller than a .357 can't kill a black bear, think again:

Those were both with .40 S&W, and 9mm isn't far behind. Check this Ammoland article out: https://www.ammoland.com/2020/03/update-handgun-or-pistol-against-bear-attack-93-cases-97-effective/
Again, if it can kill a black bear, it can kill feral hogs and snakes. If you can't get your hands on a .357 at the moment and have to use a 9mm or something like that, fret not: that's plenty.
