I know nothing bout pigs,other than I like ham and bacon.
That said, hiking and hunting are like apples and oranges.
Hiking into a situation with a dangerous animal,most likely
won't allow you to pick your shot.
There's a good possibility while hunting, one will get to pick their shot.
If I hiked, I would have a a front ww2 type tanker's holster
and a 4 inch smith 44 mag. slow,em down and then them off.
