*EDIT* I have fixed it!
What I would like to do is get out my camera+tripod and do some shot videos of various things (speedloader, CPS 1500, 2000, 2500, and now my precious XD) but that's not happening for a week or so. In the meantime...

Notice how it's different from a normal CPS 2000/2500. Also, the trigger is thicker and a more durable plastic. The hard PC isn't glued. Etc, etc...
So what's actually wrong with this cannon? Nothing, well sort of. The fact is, that the pressure generated is so much, that the internals turn and twist when you try to pull the trigger. I could barely pull the pin once the gun was pressurized; and seeing how I have manually pulled the pin on a 3000, 2000 MK2, 2500, I can attest to how powerful this thing is. So what did I do?

Right: Original hole for trigger wire --- Left: New hole ----Also, I apologize for the crappy picture.
So I figured I would try this. It's not a hair trigger, but now when you pull the trigger it starts to move the firing pin back immediately instead of just moving the wire back 1/4 inch, accomplishing nothing. Now, without pulling the trigger back all of the way, it can be fired reliably. Like it was supposed to be! It's reversible, you can't see it, and unless you drill too many holes and end up with a slot, you can't screw it up. And it works!

Man this thing is fun. I can't wait to try it out again, VS my CPS 2000 and 2500. This thing is scary, I definitely will be mindful of what I'm shooting at.
I will note that, after a careful tap shot (that drains 1/4 of the PC), it does sometimes start leaking pressure... but I'm not using this gun for the shot time!
