it may be apples to oranges, but per a recent pearce article, i can run a 300grain plus bullet to 1500fps out of a redhawk, that i like a lot better than those clunky alaskan's.
We don't have grizz's, yet in arizona, wait a while for reintroduction. But i have had two personal up front and personal situations with black bear(20 feet or less) and that is where big bore handguns and a marlin guide gun got my attention.
That redhawk is .45colt
