It's been a long time since I last had a case head separation but yesterday I finally got one (old batch of Remington Cyclone) and along with the loud POP there goes my extractor, spring, that little ball detent and the extractor plunger.... 
I found most of the parts unbroken laying on the shooters table however the extractor plunger I couldn't find.... I jumped on Numrich's website and they do have a replacement part listed under "PPK/s" however it doesn't specify if it's for the 22lr, 32 auto or 380acp...
So I sent Walther customer service a email to see if they could send me a replacement part. I'm guessing they probably want me to send it in so they could take a peek at it... But hey, overall I am very happy with this pistol. I've shot thousands of rounds thru it without any major issues until now...
