Barrel tightnening?

With either method, I would add loctite to the threads on final assembly; after confirming headspace is in spec.

If this is not one of the matching pistols, you may want to consider a different barrel, that one does not have the greatest bore anyway; of course that would mean having several barrels to choose from for fit.

Lugerdoc or GT could help you with a different barrel.

Thanks. From initial observation it appears to be all matching. Even though the bore is not in the best of condition, it would be nice to keep the original barrel if it can be fixed properly.
