The newest innovations to gas blowback pistol technology have arrived with G&G's GPM92. A new whirl cylinder valve is designed specifically to prevent frost buildup on the valve when the sidearm is fired rapidly. When frost builds up on the valve it can cause sluggish movement of the valve or even sticking which causes inconsistent FPS or even the prevents the pistol from being fired at all. G&G also included a magazine output valve that is designed to collapse and vent gas if the magazine is ever over-pressurized to prevent it from exploding. The pistol is build using full metal construction from maximum durability. Including functional, ambidextrous fire selectos and a 20mm accessory rail for adding lights or lasers, this 1:1 scale replica M92 is a solid, dependable sidearm for any airsoft encounter.
