Co2 Airsoft pistols work effectively by compressed Co2. You know, two types of Co2 Airsoft pistols are available. These are- a Blow Back C02 Pistol or a Non Blow Back C02 Pistol. Blowback pistols feature a moveable slide. This slide shoots back with each shot, but nothing comes out just the pellet out of the barrel. These features offer both recoil and realism.
