Need help identifying a Luger S/42

[Kiwi]

Check there is no obstruction in the barrel.
Double check there is no obstruction

Another way to bulge a barrel is excess oil, the bullet creates a 'wave' of oil.
Too heavy an oil such as used for storage.
Clean the barrel with solvent
Then a patch with gun oil,
and run a dry patch down before shooting.


If all clear - should be OK to shoot
