I have a problem with CO2 leaking out of the gun. I have a Pure Energy Vertical Regulator on my gun, and when I attach my Co2 tank, it just flows out the bottom of the regulator. I also have an electric trigger, so i was wondering if this is a problem with the regulator, or the trigger. The reason I wonder if it is with the trigger, is because i'm not sure if the co2 is supposed to always be flowing to the regulator, shouldnt it only flow there when the trigger is pulled and only excess co2 released from the regulator? So could it be a problem with the trigger or the mechanism that holds the air back, until the trigger is pulled?
