We dont really have grizzly here, and not many moose either. .357 is about all you need. And with propper selection you can find a load+gun combination that will suit most any situation that can arise here in wa. A 4" barreled 357 is legal for hunting, can still be concealed carried with relative ease, is fun at the target range, can be great on the trail, take small or larger game, etc. The federal hydrashock 158 gr load is a good multipurpose round, with 18" of penetration will easily stop a mugger or mountain lion, and with shot placement stop a black bear.
