Take a look at the Alaska Outdoor forum Handgun thread. Some good info. I carry a 629 .44 Mag when my .375 H&H or 12 gauge is too cumbersome, but I don't feel real confident with the 44. The ammo is Barnes Supreme 300 gr Hp...but a small hollow point shape...I have never shot anything with the .44. If I had a spare $1000 I would get a muzzle braked 4 inch Smith 500. Like Reaper said...heavy and hardcast bullets.
Keep in mind grizzly/brown bear do not die as easily as a black bear. A killing caliber/bullet is better than a hunting caliber/bullet.
