Damaged breach block
After the OP, send me a link to this post.
I want to add my 2 cents.
One aspect of extractor movement is overlooked in everyone's response.
Any combination of case - extractor- breach block connection, will damage the case first, if the case is brass. Examine the cases if possible.
To damage the breach block in such a way by extractor movement , it has to do so by interacting with a metal.
The only metal extractor interacts with , other then breach block is barrel and slide.
I have seen this happen in cases of a barrel extractor clearance hole has been cut short or with a wrong angle,
or barrel twisted out of alignment just to the point where extractor slams in to it.
In any case extractor must found an obstruction on it's way, that has forced it up, without anywhere to go it pulled the breach block weakest point out.
At this point, i recommend, changing the barrel or cutting it back a turn with cutting all back geometry deeper for clearance as part of the rework.
Change the breach block and examining the extractor interaction with all parts , without firing the gun.
and possibly changing it as well, as it must have internal stress from such a damage.
I can do the rework if needed, and i have all the parts in stock.
Hope this helps
