Learn more about Gas Blowback Pistols [GBBs]There are two main options when shopping for an airsoft pistol: blowback or non-blowback. Airsoft blowback pistols feature many realistic features, similar to that of a real pistol, including a fully functional slide, hammer, realistic field stripping, and simulated recoil! Gas blowback airsoft pistols cycle the slide back and forth after each shot, delivering recoil similar to that of when firing a real pistol. Non-blowback pistols still utilize green gas to propel the BB but do not have moving slides that kick back. Most any airsoft gas blowback (GBB) pistols will shoot at 300-400 FPS. All gas 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.
