I've had the same problem with my M9. I can only single action it. If I try to double action, the hammer just clicks and the slide doesn't come back far enough to load the second BB. After a couple of that, the slide will come back when I depress the trigger, and won't slide forward until I let go. I haven't taken it apart, but I think one of the things could be a dried seal. You do use silicon oil right? Put a couple drops on the end of the mag where you fill it, or if your propane adapter has a oil well, take off the screw and put it in there.
