 As with the current .454 Casull and .44 Magnum versions, it too now sports a "conventional" satin stainless-steel finish, along with the Hogue Monogrips.Introduced in 2005, the Ruger Alaskan is Ruger's first short-barrelled, big-bore revolver, conceived by Ruger president Steve Sanetti and intended for defense against large, dangerous animals.The .45 Colt may be an alternative for concealed against human attackers due to the fact it does not possess the capabilities of penetration like that of the .454 Casull.
