Go for it! With the caveat, you should have some experience with heavy-recoiling revolvers under you belt before you step up to the 500.
I just got one (xmas x frame, present to myself), and I've only managed to get out to the range once with it. I will confess that I did not do my best shooting with it, maybe it was an excess of adrenaline
But, I certainly enjoyed shooting it, and look forward to becoming as competent with it as I am with my other guns. There is something about hurling an oz. of lead downrange that is gratifying, at least when you hit your target!
