Try putting back in the OEM hammer and test it. If that solves it then that is your issue and you just need to reprofile. If that doesn't do the trick then try putting most of the OEM parts back and remove the charging knob to test and start from there. With all of the changes made it would be hard to diagnose with all of the different variables.
Also the best thing you can do is start reading this forum for similar threads from the past.
I agree that you should read up on past threads that discuss these issues for a broader understanding on how to get your gun running reliably. If you get your answers only from recent threads you will only get a narrow set of answers. When this place was really roaring with activity and debate from experienced S12 guys a lot of good info was put out on this board.
