Airsoft CO2 pistols, not to be confused with gas pistols, run on, easy to find, 12g CO2 cartridges rather than gas or propane. CO2 Airsoft guns typically shoot at a slightly higher velocity (FPS) than gas pistols, and run on small, easy to store CO2 cartridges. There are two main options when shopping for an airsoft CO2 pistol: blowback or non-blowback. Airsoft blowback pistols have slides that kick back after each shot, delivering a recoil similar to that of when firing a real pistol. Non-blowback pistols still utilize CO2 to propel the BB but do not have moving slides that kick back. 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.
