Snype, if the gun is still firing, and the trigger is a bit different, it's probably the trigger spring. I just don't see how you can argue that. If it were almost any other spring, the gun would fail to operate at it's full potential. Don't worry about the spring, just play with it. It may not be the trigger spring per say, but it's defiantly one of the trigger springs (front trigger spring, trigger slider spring, ect.). The gun simply wouldn't work the same, maybe not at all, if it was an important spring. Please just don't worry about it and play with it. You fired it and it works, so I don't see why you're so concerned.
