Description Delivery Returns

The GX45 MKI Silver combines refined styling with G&G’s performance driven gas blowback (GBB) mechanics. Built on a full metal slide and frame, it delivers sharp blowback feel and efficient gas use, wrapped in a sleek silver finish.

Product Features:
Sleek full-metal slide and frame in polished silver finish
Whirl Cylinder Valve system for minimal frost and consistent performance
Skeletonized hammer and trigger for reduced pull weight and style
108mm inner barrel, outputs ~300–320FPS with standard 0.20g BBs
Contoured grip panels, ambi thumb safeties, and adjustable rear sight for control and accuracy
Includes 26-round magazine, speedloader, and presentation case
The GX45 MKI Silver (GAS‑GPM‑MKI‑SBB‑ECM) elevates the GX45 MKI lineup with a polished silver finish that balances standout styling with G&G’s proven function. Weighing around 930g and measuring 220mm in length, it maintains the compact footprint and solid handling of the MKI series.

Featuring G&G’s Whirl Cylinder Valve technology, this pistol delivers efficient gas cycling with reduced cooling — ideal for fast-fire usage. The skeletonized controls enhance both aesthetics and trigger feel, while the adjustable hop-up over a 108mm barrel ensures accurate shot grouping and consistent velocity between 300–320FPS.

User comfort is ensured with ambidextrous safeties, ergonomic grip designs, and fixed front plus adjustable rear sights. Each unit includes a 26-round magazine, speedloader, and branded carrying case, catering to both casual and serious players.

In summary, the GX45 MKI Silver couples stylish presentation with dependable G&G performance—making it a refined pick for both field use and collectors.
