If the pin is this long, then it could be your problem. The pin should only be 0.750".

Therefore, it sounds like an on-off issue where the pin is not clearing the top oring when the trigger is released.
The other issue would be if the bolt is stuck. You can check this by putting the valve into the mag without a bolt spring on it and don't add air. Hold the trigger, tip the gun forward and give it a bang on the back or side of the valve to see if the bolt will slide forward. If the bolt moves freely, then you know its not a bolt issue.
Except for the Automag in front, its usually the man behind the equipment that counts.
