Just an insane beast. It WILL beat the hell out of your arm and wrist with full house loads. The other poster was right, if you know someone with a Mossberg pistol grip let them let you shoot a few 3" slugs out of it and that is almost exactly what a compenstated 500 S&W Mag feels like on the palm of your hand. It is sick fun though for about 15 to 20 shots. Even more fun is a 460 S&W Mag. Just as much if not MORE blast and noise with MUCH less beating the hell out of you, plus you can shoot 454 casull and 45 LC through the 460.
