This is the correct alignment of the barrel and breech block for any GSG-522 models. Note the extractor notch in the barrel matches up with the extractor notch in the breech block.
This is incorrect. It shows that the barrel notch has backed away from the breech block notch.
This is also incorrect. There is such a large gap between the face of the breech block and barrel that the gun will not fire.
