HELP - Jennings J-22 question: A friend recently got a J-22, fired it and ask me to show him how to clean it. I broke it down, cleaned it, and reassembled it; he watched the process. A few days later he fired it at the range and decided to clean it himself. To get to the point, or the problem, the gun doesn't function at all. The firing pin is protruding from the 'take down button', which I believe is because it's in the cocked position and I'm unable to dry fire it to get the firing pin flush with the back of the 'take down button', which means that I can't disassemble the weapon - pushing in the 'take down button' doesn't release the slide as it should…………what can I do to disassemble the weapon and correct the problem?????
