The piston can jam through a couple of reasons. The nylon piston head can absorb moisture over a period of time and swell in diameter. Also the piston buffer washer can disintegrate and become all gooey through bacteria. There are a number of methods for getting the piston out. I use brute force with a hammer and drift on the piston cocking slot. Others use chemicals and heat. I skim the piston head down and refit it, and make a new buffer washer.
