A5 Problems, Help Please!

So i got a new A5 with an e grip a little while ago. I used it for the first time today and i was having an issue. No matter what setting the E grip is on, or even if the e grip is off, whenever i fully pull the trigger, the gun will give a burst of CO2 out of the barrel similar to the sensation when you are low on gas. The ball that was in the chamber will shoot, but the cyclone feeder seems to lock up whenever this occurs, and then goes back to normal after if stops. It lasts maybe a second. It was very annoying having to just pull the trigger part way for my gun to work correctly. I tried multiple CO2 so i know the CO2 is not an issue. Any help would be greatly appreciated. If anyone needs clarification on any part of my post, i will be happy to give more details. I have nothing special done to the gun internally or gas line wise. Just a regular gas line on the end of the gun. I do have a double finger trigger if that matters.
