If you are the same person who asked the choice between the Glock 19c and the Sig Pro, I just answered U over there.
Here, it seems like U are looking to widen your range.
U will get tons of ideas from people here probably - As a new person to handguns, I would typically recommend you get a 9mm. Cheap to shoot and not much recoil. There are many good choices out there. It would also make a decent home defense gun or a carry gun if you get a permit later.
1911s are nice guns - but as a newbie, I don't know if I would recommend one as your FIRST handgun. The bullet size - 45ACP is good - but many 1911s can be picky and can take some work to make them reliable (some do work right out of the box, but not always). As a FIRST gun, I can't make the recommendation (Mike, another member here, has suggested the same thing to others in the past).
But, U added a new wrinkle to the whole issue - U want it for defense in the wilderness. IF that is what I wanted out of a gun, I would want something more powerful than a 9mm and a 45ACP. At a minimum, I'd get a 357 revolver w/ 357 rounds. This might be a good option for you, because you could practice with .38 rounds until you get good with the gun. At some point, U'd have to practice with the more powerful 357 rounds that you would want to carry, though.
The possible problem with this is that U wanted a semi-auto. For a semi-auto in the forest, I'd probably get a Glock 20 - a 10mm handgun. But once again - That might not be the choice for someone new to handguns. I think you are wanting a powerful handgun, but don't yet have the practice with something like a 22 or a 9mm yet. So, it's really tough to make a recommendation.
I'm not a revolver guy - I prefer semi-autos. I have 6 of them. But if tomorrow, I wanted to go out into the forest and wanted protection, I'd probably go buy a Ruger GP 100 - a stainless 4" barrelled 357. A .44 would be an even better choice, if ya came in contact w/ a bear, but i personally would stick with the 357 and pray it was enough
