barrel relining service?

The P1 barrels had a big problem; the straight barrel liner (no step) would gradually slip forward causing excessive headspace. Walther resorted to a pin in the chamber area to hold the liners in place, but the pin was not positioned correctly initially and the liner would still move forward. They eventually got the pin repositioned and it was considered 'fixed'.

Mark Castel has explained this in John D's sister P38 Forum, along with pictures, IIRC. Mark (who is also a member here) also was kind enough to explain it to me and sent me pictures as well as examples of the liner 'creep'. I think I also showed examples [pics] in my thread over there explaining how I relined P1/P38 9mm barrels to 7.65mm Parabellum.

Might be worth a look.
