Got a quick question gents. Been having a bit of trouble with Tac-One. It airs up fine and doesn't leak at all until I fire it. Once fired, a bit of air will start to leak from the barrel. If I pull the trigger all the way and hold it in after the marker fires, the leak stops. Upon release it starts again. If I pull the trigger very slightly, the air leak lessens a lot or out right stops.

Any suggestions?
