What about a .380 or .38 and what are differences between these two?
Those are two different rounds. The 380 ACP is commonly found in small semi auto "pocket pistols". It is not suitable for protection against animals.
A .38 Special can be safety fired in a 357 magnum firearm. It is just a shorter, less powerful round. It's fine for target practice because it's cheaper but for carrying in the woods you'll want to load it with 357's.
This picture should give you an idea of what the rounds look like.
