Off topic a bit but I need to know: how did you crack that barrel? Too many high-pressure rounds? Too many rounds, period? That picture has me paranoid. I'm examining my 637 millimeter by millimeter.
Actually thats the alloy frame thats cracked, and thats where those airweights always give, cause its the thinest part of the frame, and receives a good jarring every time the bullet makes the jump from cylinder to forcing cone.
