FWIW, I had the same crack in my 637 and had gutted the lock. Sent her back on their dime with no grip and no ILS. They sent her back with no grip and only the part in the hole for the key was put back. They didn't put the flag, the pitchfork, or the springs back into her. The logo on the side opposite the swing out isn't centered anymore either. It's high up to the right. I got a new barrel and frame and the rest was from my original gun. I assume they mill and finish frames, set the barrels, and then set them aside like this. Turn around time on mine was almost exactly two weeks. As they are currently making ILS free 642's I would think that is what you will get in return... Be glad this didn't happen a little over a year ago...
