Check out this lawyer who is probably looking to sue S&W because someone blew his hand up by supporting a 460 xvr with his hand under the trigger guard. He got blasted by the blast out between the cylinder and forcing cone.
Duh, don't put you hand there. Pretty much common sense. How is this S&W's fault?
Warning, the photo in the site shows a wounded hand. But seriously folks, if you don't know what you are doing, don't fire a handgun. Or a rifle for that matter.
Maybe I'll send them a photo of my perfectly good hands and tell them I've fired an S&W 500 and managed to survive.
