Redhawk,
I know that I am not supposed to be jealous, but your story is really getting to me. Seriously, congrats on the great deal. I already own a Dan Wesson 445 supermag with a 4" compensated barrel (a true 4" barrel, over 5" with the compensator), but I am really tempted to get one of those 500 S&W "snubnose" guns. If I saw one at that price, I would probably get the shakes or something. I think I am going to wait a little while to see what the endurance of the small 500's turns out to be. If there are no reports of them shaking loose over time (which I don't really anticipate), I will probably eventually end up with one.
