I pulled the trigger and smoke and burning powder came spraying out the ejection port. Didn't really burn me but it did scared the crap out of me...
There was a cartridge jammed in the ejection port so I had to take the slide off to clear it.
After looking things over, I noticed that the extractor was gone :-[
The primer had blow out when I fired it and most of the powder came out with it. It also blew out the extractor and the little pin that holds it in.
It was an indoor range and after looking around I actually found the extractor and the pin. The spring was still in the gun. I was sure something was broken so I packed the stuff up and came home.
After a little cleaning and inspection, I realized that nothing was broken and I was able to reinstall the extractor. Loaded up 3 or 4 mags and hand cycled them to see if everything was good to go.......all is well with the world.

It did get me thinking about the need for spare parts. I may get another P64 (3rd one) or buy some parts from one of the guys on eBay while they are still have them.
I still can't believe I found the tiny pin on the floor of the range...
