Well, Having occasion to come upon a 500lb blackie which happened to be munching on the remains of my Moms' moose, I can state, without reservation that I wished to have been still carrying my rifle as opposed to the .357 at my side. I fired two warning rounds which didn't deter the bear from his dinner. It worried him but didn't scare him off.
I have to agree with whomever said that a pistol is only good to fight your way back to the rifle that you should not have dropped in the first place.
extra weight, don't bother.
