I thought my Lindner was off face, but it turned out to be a worn locking bolt. I had to take the action completely apart - the locking bolt is the last thing to fall out. I then welded up and dressed down the worn part of the locking bolt that engages the underbite on the barrels. It was a long job, but proved to be very interesting - the inside of a Lindner is a real treat to behold!
Also - I determined that the gun was not "off-face" by pulling up on the barrels (as if closing it after it was closed) then trying to move them side to side. I used my stocking vise to do this, but it can be done in your hands. If you cannot move the barrels side to side after pulling up on them you have a locking lug issue. If they still move after pulling up it is a hinge pin / barrel hook problem.
