So how is it that Smith & Wesson continues to pull it off with their production revolvers? The S&W wheel guns are considered to be the industry standard now. In a world that’s gone all-plastic, the Colt revolvers seemed antiquated. There is a lot of steel these old guns, which adds to the expense and the weight. The machines that produced them were run by humans, and not by computers. The smiths at Colt had a lot of man hours in the finish work on their double-action revolvers. These guns were among the last of an era. Why did the guns fade away? The answer isn’t too complex.
