Nice pea shooter, but I found your bear gun right here:
Seriously though, congratz on the purchase. For what you wanted, I think it's all round a better piece than what you had. Capacity for a more powerful round while still being compatible with the 38 special you're used to. Reliable, not that your old one wasn't. Probably most important to me, it isn't a snub nose, so better stability, accuract, and aim IMO.
Wrong gun. Dirty Harry carried a .44 Magnum S&W model 29, or a .44 Auto Mag pistol which used .44 AMP. I also wouldn't taunt a bear like that regardless of what I was carrying. Especially if I were carrying that big mofo I linked above, I think I'd be more scared of shooting it than the bear attacking. <Haven't actually wanted that video yet myself BTW.>
