Failure to extract. Rough chamber?

I have a Star B. Full size 9mm (9x19).

The gun will shoot, but not extract the round. After firing the spent shell remains chambered, slide closed, extractor still engaging the rim. I can manually slingshot the slide and the round extracts and ejects cleanly. Next round strips off the mag and loads just fine. It acts just like a gas gun (like a FAL, AR or AK) with the gas port plugged.

I'm thinking the chamber is a bit rough and the brass is grabbing on to it as it expands when the bullet is fired. Once the brass cools a second or two later, it contracts and allows me to extract it by manually cycling the slide. Does this seem likely?

If that is the case, what is the best way to clean up the chamber?
