Smith & Wesson wanted to deliver maximum power for serious handgun hunters. The power they sought required an entirely new frame, the massive X-Frame, and was the basis for the Model 500, the most powerful production revolver in the world. This ushered in the era of the "big gun" and was only the beginning. What followed was a Model 500, strong enough for the biggest game, yet easy to carry. 8-3/8" barrel. Stainless steel finish.
