C96 ejecting 2 rounds...

[Curss]

I do have a repro magazine spring from Wolff gunsprings on standby. That would be my second guess, but it will require fitting, something that I tend to leave to gunsmiths (even though those are few and between and getting hard to find). I honestly don't mind if it is just a 9 round pistola, I'm just glad to have one that works reasonably.
