By the way... I advise not beating on the thing or otherwise attempting to retract the slide. What needs doing here is the fixture the gun on a mill table and use an end mill through the ejection port to precisely cut out as much of the barrel as possible without touching the slide in order for it to release.

Attempting to force the split & expanded chamber to retract into the slide beneath the locking lugs poses too much a risk of further damage IMO.

Cheers
Bill
