As far as a side arm for what you have described, I am very partial to my .44 Revolvers or my.45's as well. I shoot nothing but hard cast lead 240grn Semi wadcutters in my 44's and 200grn Hornandy Encapsulated Wadcutters in my .45's. Very accurate and give you the energy to break heavy bone or skull when the need arises.
NO HOLLOWPOINTS!!!!!!! The don't give the penetration needed in the lower power handguns to take care of business in a hurry. They are fine as a regular carry round, but if you are after hogs mainly, they just don't cut it. We have a big plastic cup on the butcher table full of broadheads, muzzleloader slugs, pistol and rifle rounds that were stuck in their gristle plates that did not do their job and drop the animal. We yet to have what we shoot fail to do the job and quickly.
