Not nearly the same thing.
You'd have to be extraordinarily lucky to stop an agitated/angry/hungry grizzly with ANY handgun. The fellow in AK who had the encounter with the Griz whilst walking his dog......yeah, he killed it but he didn't stop it, though he sure came close:
"Rolled him at 5 feet and he
skidded to a stop 10 feet BEYOND where I was
Shooting from...."
"Stop it" means that the animal does not get to you. He was lucky to survive and he knows it. His sidestep probably saved him from real hurt (he ended up on his butt). Had the animal only run him over (as opposed to mauling), he'd have been in bad shape.
