I recently had a problem with the pt spacer on my automag (air leak mid trigger pull) so I solved it by grinding down the spacer slightly and now it doesn't have any problems there. But now i've noticed a new problem (i don't know if it could be related to the spacer or not), When i gas it up, I can hear it leaking slightly somewhere near the classic valve. even when I hold the trigger it still leaks. Is this related to my newly shortened spacer? (the leak is nowhere near the barrel) Or is it something else?
