AK, I totally agree. and in your neck of the woods it is a necessity. if they were up there I would understand.
These guys are already carrying shotguns while bird hunting. Their concern was a feral pig attacking them while they hunted. That is unnecessary.
You don't need an excuse to carry a handgun in the field, just carry it. You don't need to envision scenarios of feral pigs attacking shotgun toting hunters to justify it. Those just don't make sense.
I've deer hunted with guys during rifle season that carried a handgun. It never made sense to me, but what the hey. I've even hunted with a guy that was afraid of the dark. Serioulsy! and lit himself up like a farmstead when he walked to and from his stand. Again never made sense to me because you are carrying a loaded long gun.
