New guy with Interarms Swiss pattern Mauser

New to the forum, thought I'd show my sole Luger and ask a tech question.

I purchased this Swiss pattern 9mm 4" barrel from a gun store outside of Chicago in the mid 1980s. When I moved to California the box and literature vanished in the move but I fortunately retained the loading tool that came with the pistol.

It has had an issue extracting fired cases for some time. I replaced the extractor spring with a Wolff spring which cured it for awhile but it is back again. I mostly shoot handloads which have no issues in any of my other 9mm pistols. Is it possible that the chamber dimension is tight and the cases are slightly too long for the chamber, causing them to stick? I'll try it with Federal ball tomorrow and see how it does and if the fired cases extract reliably.
