Airsoft Megastore reviews the new G&G GPM92 Gas Blowback Pistol that incorporates a new way as compared to the Marui-based GBB Pistols. Based on the M9 handgun this has a whirl cylinder valve that will provide high speed rotation and a gas filter that only allows gasified gas and restricts liquid gas in the magazine.
