It's all gone, but if you scroll to the bottom entry in the list they still have available a 9 x 23mm Win. I'm not familiar with that cartridge, but if the diameter is okay, it wouldn't take long to shave off the extra 4 mm case length to make 9mm Luger cases.
Happily, I have a bunch of 9mm Luger from years of policing my brass when shooting out in the desert, something a lot more people are doing these days.

I recently found one case in my collection that was Berdan primed! I've never heard of such a thing, and rather than waste my time with it, tossed the case in the scrap can. I have no idea where I picked it up, and can't read the headstamp. Weird things happen in the desert...
