Easy to get it to the point of pulling the pistol apart to see the total story of the damage,

Leather up the jaws in a chuck vise to protect the finish on the slide, then use a end mill in the mill to remove the cracked  top chamber section of the barrel hood.
This will give enough room for the barrel hood to clear the slide to pull the pistol apart.

As for rebuild, just depends of what is out of spec out, and what is not, and would rather fit a new barrel to the rig myself, then to have STI/SVI fit one instead (yes, even on a Edge).

Now the mystery question, and what caused the barrel hood to shatter crack, and not the brass to split instead.
For limited class, I run a 180 jacket bullet behind N320, and this load hits major power factor just fine, but not at a pressure that is going to hammer away on the barrel, even when practicing hard for long periods (read 20K is nothing on a slide and frame, since these should be able to be peened and last for 100K or more of rounds).

And why the jacketed bullets when we all know that you can hit higher speeds with less pressure using a casted lead round?
Its the fact that the leaded bullet is going to start leading up the barrel with the amount of round that is common to run in practice, and this is going to jack the working pressure up of the rounds to cause problems then.
