Smee78, that would be your perogative whether to send it in. Me, I would keep it as is. My understanding (the pros can correct me if I'm wrong ), is that with very hot .357 magnum loads, the cylinder could possibly bind to the extent that the cylinder would not open.
That was also true with the Model 19. But to shoot reasonable loads, (all factory loads would be fine,) but if you load your own, don't try to be a hero and see how hot you can shoot. It's not good for a very good revolver. Just my 2 cents.
