G&G GX45 MkI (EU) Gas Blowback Airsoft Pistol – Black

The G&G GX45 MkI (EU) GBB Pistol is a compact, full-metal sidearm built for realistic handling, reliable gas efficiency, and consistent skirmish performance. Finished in a clean matte black, the GX45 MkI combines modern internal engineering with a practical, ergonomic design—making it an excellent choice for both new players and experienced skirmishers.

At the heart of the GX45 MkI is G&G’s patented Whirl Cylinder Valve system, designed to improve gas flow, enhance efficiency, and reduce cooldown during rapid firing. This results in smoother cycling and more dependable performance, even when firing quickly in CQB scenarios.

The pistol features skeletonised trigger and hammer components, reducing moving mass for a crisp trigger feel while adding a premium, tactical aesthetic. A 108mm inner barrel paired with an adjustable hop-up delivers consistent accuracy, producing approximately 300–330 FPS with 0.20g BBs, keeping it site-friendly and reliable.

Ergonomics are well considered, with textured grip panels, ambidextrous thumb safeties, and a fixed front sight with adjustable rear sight for confident target acquisition. Supplied as a complete package, the GX45 MkI includes a 26-round magazine, speedloader, and protective hard case.
