Usually caused by debris in the small air passage from inside of gun to feeder piston. Easy to check. Remove the head and pull out the cylinder. Debris in the chamber is usually small pieces of oring or the lower bumper is coming apart. This debris will enter passage to feeder which is visible at bottom of chamber. If debris is found, clean chamber, passage, and feeder chamber. Debris will lodge on the oring between the body and nose. Clean and replace parts as needed. If the gun was found to be clean inside, suspect weak or missing feeder spring/s. Good luck/
