Cracked rear toggle and hammered breech block - must have been abused or shot a tremendous amount in its history.
I agree, just buy a new mfg, or a used good condition BB and move on!
If 4.5 gr of VV340 functions your luger well, I'd also suspect the main spring is weak.
Perhaps you should consider changing it, that could have contributed to your problems.
Check the inside back of the frame also for hammering.
