Learn more about CO2 Non-Blowback PistolsAirsoft CO2 non-blowback pistols, not to be confused with gas non-blowback pistols, run on 12g CO2 cartridges rather than gas or propane. CO2 non-blowback airsoft guns typically shoot at a slightly higher velocity (FPS) than gas non-blowback pistols, and run on small, easy to store CO2 cartridges. Airsoft CO2 non-blowback pistols are typically more efficient than blowback CO2 pistols, because they do not use CO2 to cycle their slide after each shot. This means that CO2 non-blowback pistols can fire over twice as many rounds from a single CO2 cartridge than a blowback CO2 pistol. CO2 non-blowback airsoft pistols do not cycle the slide back and forth after each shot, unlike CO2 blowback pistols. All CO2 pistols are semi-automatic repeaters; some higher-end gas pistols feature full-automatic firing modes that shoot rapidly while the user holds down the trigger without letting go.
