Unusual malfunction .30 Luger case

That case expansion is abnormal. Double check that it's in .30 Luger caliber (see the FAQ for photos) and measure the chamber to see if it's in specification.

I've never seen that much case expansion in any handgun using the proper ammunition.

The SAAMI cartridge specifications are here:

(Yes i know SAAMI wasn't around when Lugers were developed, but their specs are useful).

See pages 36 and 43 for dimensional drawings. The .30 Luger cartridge case has a considerable taper. it almost looks like your chamber was reamed out larger than the base. It almost looks like it's been loaded and fired from a 9mm chamber.
