I didn't hunt hogs, but my dad, he went to Arkansas to hunt some one year, and he had to take a rifle of a certain calibre and a handgun of a certain calibre. Can't recall what the limitations were, but he carried a semi auto Remington .30-06 and a Ruger Redhawk (the SA only .44mag). Reasoning was they charge when messed with and if that rifle fails, you need something else. My dad grew up watching "Ole Yeller" as a kid, so he probably had that in mind when hunting them, this was his first hunt. They take the damage they can do seriously in Arkansas at least.
Personally, were I to hog hunt, I'd probably use my .50Beowulf, I've heard from lots of other hog hunters that it was THE rifle for dropping big hogs fast. The 300+ gr. bullets seem to work best, the FTX, the XTP, Speer GD, but don't discount the 334gr. plated Rainier --it was specially designed for this rifle and has a much thicker plating, but the inside is pretty soft and while it doesn't mushroom, it does flatten into a half-doller size slug. Super accurate to 100m, max range for an accurate shot is 200m (it falls like a brick after that). For the handgun, I suppose I'd just carry a 10mm auto, probably a G20 or 1006 with very heavy loads. Something that won't jam and can put lots of heavy rounds into a charging pig fast.
I guess if you aren't required to carry the pistol and don't want to, that Beowulf would be great, but only if you are hunting big pigs. It'll blow the smaller ones up I'd suspect.
Before saying the Beowulf is overkill, consider its ballistics first. It is basically a semi auto rifle version of the .500S&W magnum with a "regular" barrel length.
