I have to admit that while I have absolutely no use for a .500, I am fascinated by the caliber and would like to own one--in the same way I would like to have a 1,000 horsepower Bugatti, or to go over Niagara Falls in a Kevlar and Carbon fiber barrel while listening to "Flight of the Valkyres at full volume. I'm something of a wuss about recoil, but my need for a light mountain rifle led me to have a custom ultra light built in .300 Win mag--5 pounds without a scope and 6 1/2 with scope, sling, mounts, and 4 rounds. I thought it would be murder, but with the muzzle brake, it's really mild--about like a light .270.
The main reason I hear folks buy thethe big S&Ws, especially with the short barrels, is for bear protection in Grizzly Country. I had a friend years ago who carried a .357 while fishing in Alaska. So I sent him a quote from one of John Gierach's fly fishing books where he says that in Alaska they call that caliber the "bear tickler," and that the main protection you get from it is that you shoot the bear 5 times then run away while he is busy laughing at you.
But if any of you do buy a .500 for, let's say, your primary concealed carry weapon, I have a great backup or boot gun to recommend: try the Smith and Wesson 13-ounce .357 Scandium with a 1 3/8 inch barrel, laser sights, and no brake. So far I have not fired mine even with plus-p loads, but it's my underestanding that touching off a full-bore 125 grain JHP changes life on earth as we know it. I suspect when I do use the heavy round the first time, I'll end up with the laser situated in such a position that I can administer my own prostate exam.
