Hey, Jim; I didn't say the factory used Loctite. It wasn't even invented then. It's well known that the Luger manufacturers used no adhesives or sealants of any kind when assembling the barrel to the barrel extension. I was merely speculating on a reason why the barrel could be loose enough to turn by hand, but not loose enough to continue turning by hand to remove. A gun hobbyist or unscrupulous dealer could have done what I said, or perhaps soldered it with soft solder. I guess we'll see if he lets us know what the problem was.
