Question now is back to Springfield for what? Obviously that barrel will have to be redesigned to support the case head, and that depends on whether or not the frame has to be modified to fit with it. How many rounds do you think they fired in testing and development of that gun? Based on your experience with it, I would guess at zero. I have spent the last week fixing a POS Sig, so I feel your pain.
There's nothing wrong with the XD...
If...and I say IF after inspection it's confirmed that there is an issue with the barrel, as I suspect is a possibility, it's a manufacturing defect, not a design failure, but without careful inspection that hasn't been determined at this point.
A part is either in spec or not...guessing doesn't count.
