I'm no big bear expert but I think you're on the right track. I bought my G20 for wild hogs, black bear and mountain lions. Never seen a lion, only one bear but the dang hogs are becoming quite the nuisance. I've had two incidents with hogs, one sow with young and one old boar that got a little hairy. Both run ins were at night walking out of the timber with a climbing treestand on my back and bow in hand. Walking up a little trail through a clearcut in that situation doesn't give you many options for escape. My son got between a sow and her pigs this last deer season and got bluff charged.

My G20 has tritium sights, stainless polished recoil rod and #22 spring, 3.5 connector and sandpaper grip tape. Carried in a Diamond D Guides Choice chest holster with fifteen Underwood 220 gr. hardcast at 1200 fps. With about 2000 rounds of all sorts the G20 hasn't skipped a beat.

Every normal man must be tempted, at times, to spit on his hands, hoist the black flag, and begin slitting throats.
