if you're having recocking problems, one thing to check are the valve secure pins. one located on the side of the marker above the frame. and one is usually located on the bottom of the receiver if you take the frame off. make sure no air is leaking out there because if it is there wont be enough pressure to push the striker back.
Yup I have seen the same problem in a few spyders and if the T.E.S valve system holding pin is the same then that could be the problem.
