Smith and Wesson not has their Outfitter series of "smaller" full power revolvers. The Outfitter series are carry versions of very high powered pistol cartridges, for example: 460 S&W, 454 Casull, and even the monster 500 S&W. These are 5 shot guns and weigh in at about 54 1/2 ounces. That's over 3 pounds of metal, add in the bullet and you go to almost 4 pounds. It's only got a 2.75 inch barrel.
My thoughts are, who the hell would want to carry this beast around and even worse... shoot it? The 454 Casull, 460 and 500 S&W's make the 44 Mag look like a pip-squeak and trying to shoot the 44 Mag in a short barrel gun is simply no fun. Popping off a full power 500 S&W in one of these sounds down right painful.
For a hike in lion territory, maybe..otherwise, no thanks.
