i actually like this better.
Im not sure how much fun .454 Casull would be out of that thing.
You definitely feel the heavy rounds out of this thing, I carry one in polar / grizzly bear country loaded with 360 grain Buffalo Boar.
Actually fun to shoot 45 long colt with the gel pack in the grip.
And nice to always have it on your belt, as apposed to the shotgun leaning against the tree over there.
