I've expressed my opinion about the Model 586 elsewhere on this forum. You got a good deal. As far as I'm concerned, the 586 is the ultimate DA .357 Magnum revolver. I'll pick it anytime over the vaunted Model 27 or the Python.
And, for cryin' out loud, shoot the thing! That's what its made for. As to marring the finish, look at the photos of mine I posted, they've had over 5,000 rounds fired through them.
