Breech Block question

tk7108 · 03-14-2011, 04:10 PM

Just picked up a 1917/1920 Erfurt P08, noticed that the breech block has a chip on the right front top, and a similar size crack on the opposite side. I think I might have found a replacement block but have some questions before I send the $$'s. Any help from the experts on this board would be appreciated!

1- Since the each Luger is in a way a 'one-of-a-kind', are breech blocks interchangeable? Are any modifications needed?

2- Haven't completely disassembled the gun as yet, but does the breech block have a serial number that matches the rest of the gun? (the number '21' stamped is on everything else).

Most breech blocks will provide a drop-in fit, although your results may vary. For a breech block, not much work will be required to fit it.
Yes, the breechblock is numbered to the gun.

This is typical of firing too-hot load/ammunition in a Luger. The shell expands excessively and blows the extractor upwards, breaking off the two side 'wings'. If it was a catastrophic failure, it may have blown the magazine apart as well. Check your magazine well for gouges or scratches...

Good info on both that cause and the fix. Any feelings about using repro block if I can't find OE

Don't use Numrich repro parts. Get a breech block from Lugerdoc, or failing that, Sarco. I had to wait ~6 months, but Sarco came through with a used 'original' for me...

99% of these I've seen or heard of that chip like this are Erfurts...dunno why...have one myself

Probably a 'dumb' question, but can you fire it with the chips in the BB ?

as long as the chips are small and confined to the area of the extractor slot, shouldn't be a problem...I'd keep a close eye to see that cracks dont appear or migrate to the bolt face
