Naturally I clean my p3at (2nd generation) from time to time, even though I have not shot it recently. In order to clean it, I must of course extract and eject the cartridge in the chamber. Tonight my p3at refused to cooperate. The extractor works fine, and is hanging on to the rim of the cartridge, and pulling it (all the way, I think) out of the chamber. But the cartridge refuses to come out of the opening in the slide. I shake it, and turn it upside down, etc. It won't come out. Never had this problem before. What could be causing this reluctance to eject, and how can I fix it? Anybody have this situation happen to them?
