Co2 is much more power Green Gas but this also means it can be much more dangerous. We recommend Co2 for long distance shooting, never close range. Generally less expensive than Green Gas pistols Co2 can seem like the way to go but it may not always be the best. If you are skirmishing with friends you need to take into account that the power of these pistols can knock out teeth and embed in skin if shot to close so ALWAYS wear the appropriate face and body protection with these pistols.

Co2 is considered a dry gas so its not recommended to leave the Co2 in the gun for more than a few days because it puts a dry pressure on internal seals of the magazine which can lead to leaking and poor performance. Since Co2 is a try gas we recommend after ever day of use doing a heavy cleaning lubricating all internals on both the magazine and pistol as well as lubricating and moving parts, no matter how small.
