So I have been wanting a gas blowback (GBB) pistol. And I have wanted a CO2 version, because we inhale and exhale CO2 everyday. I really do not wanted to get green gas or propane in my body. Luck would have it that AirSplat offered an $1 GBB Pistol Deal. Through the deal, I got a full metal WE F226 (Sig Sauer P226 replica). It's a good gun, but it is a green gas gun, rather than a CO2 gun.
I did not know anything about GBB's at the time. So I bought into AirSplat's claim that you can use the AS Tactical CO2 Filling Tank and Barometer to fill a green gas magazine with CO2. While it is technically true that you can use it to fill a green gas with CO2, you really "can't" because it is dangerous.
You see CO2 is stored at ~800 PSI, while green gas is stored at ~150 PSI. The pressure difference to too great for a green gas magazine to handle CO2 properly.
Nevertheless, I thought it might be worth a try to fill a green gas up to ~150 PSI worth of CO2, using the AS Tactical CO2 Filling Tank and Barometer. This is the story of what happened.
With the AS Tactical CO2 Filling Tank and Barometer lined up to the KJW P226 green gas magazine, I started the gas transfer. But it immediately filled the gas magazine with ~900 PSI of CO2. The transfer was way quicker than I expected. I found that the pressure in the gas mag so high that I could not release the gas by pressing the gas release button. It's stuck in place.
I got my paintball facemask on and put on my airsoft gloves. The KJW P226 gas mag held. There was no leaks. The magazine didn't explode, but the gas couldn't be released. Of course, the WE F226 couldn't fire it at that pressure either. So I pulled the magazine out of the pistol.
I laid it on the table and got my flat-head screwdriver and rubber hammer. I wanted to use them to release the pressure. I place the flat blade on the gas release button and gently tapped it with the rubber hammer. Nothing. So I tapped harder. Nothing. Finally, I banged the screwdriver with the rubber hammer.
Bang! I heard a loud sound. The mag is no where to be seen. I looked around. It has flown five feet and landed on the floor. I picked it up. It looked intact. Except the Gas Route Rubber Seal had been blown clear off the mag. The gas release button was still too hard to be pressed. Ok. I guessed that I needed a vise.
I walked over to the vise on the other side of the garage. Fastened the magazine onto the vise. Then I tapped the gas release button hard with the screwdriver and the rubber hammer. Finally, the CO2 is released and the gas release button can be pressed by hand.
I was surprised that the KJW P226 gas mag held the pressure without a problem. But it looked like the mechanism used on the mag could not handle the high pressure.
So that's my real-life experience of feeding CO2 into a green gas magazine. I had to take the gas mag apart and re-install the Gas Route Rubber Seal. But that's story for another day.

Thanks man, I was looking at getting on of these to fill up a green gas mag also. I'm glad I found this before making the purchase. Maybe if I find something with a regulator, this idea will work.

Keep me in the loop, John. I would like to know if a regulator would work.

So I bought this under the same assumption with my kjw mark2 sniper rifle, and it expanded the magazine....permanently.
I should've done my research prior to purchase......

I've been using the "Devil Hunter' mod for my GHK gg mags for a while.. it works great and the mags can take the extra pressure... Now after a while i was experimenting with the same mod for a GG pistol mag.. My pistol is a KJW P226 with a co2 ready nozzle... First i tried on of my WE pistol mags. Just as the story above the mag held the co2, but the release valve was stuck in place, no movement until i used a screwdriver and hammer.. after that i replaced the we gg release valve with a KJW p226 co2 fill valve. This was succesfull. i only had to fill it for a couple of seconds and the mag give's the same pressure and amount of shots as the normal co2 mag did.. My only concern is if the gastank of the mag can handle the extra pressure
