Umarex GHK Glock 45 Gen5 MOS GBB Gas Airsoft Pistol – Black

The Umarex GHK Glock 45 Gen5 MOS is a high-end gas blowback airsoft pistol designed for players who demand realism, reliability, and competitive performance. Officially licensed by Glock and manufactured by Umarex with premium internal components from GHK, this replica faithfully mirrors the look, handling, and shooting experience of the real Glock 45 Gen5 MOS.

The pistol features a durable aluminum slide with a black Cerakote finish, including the outer barrel, and authentic Glock markings. A strong and realistic blowback system delivers crisp recoil and full slide travel with every shot, making it ideal for CQB, training, and MilSim environments.

Premium Internals & Realistic Performance

Thanks to GHK’s high-quality internal parts, this Glock 45 MOS offers excellent gas efficiency, durability, and consistent performance. The redesigned trigger mechanism provides a smoother trigger pull and faster reset, while the newly developed metal hop-up chamber allows quick and precise adjustment for optimal accuracy.

The pistol is CO2 ready (CO2 magazine not included), making it suitable for high-pressure operation and reliable performance in colder temperatures. It is compatible with GHK Glock 17 Gen3 and Gen5 gas and CO2 magazines, offering flexibility for different play styles.

Gen5 Improvements Over Gen4

• Fully ambidextrous controls, including slide catch and reversible magazine release
• Removed finger grooves for a more ergonomic and universal grip
• Beveled front slide for easier holstering
• Enhanced surface finish
• Slightly revised sights for improved sight picture

MOS (Modular Optic System) Configuration

This MOS version features a factory-cut slide designed for mounting micro red dot sights. The pistol is delivered with a pre-installed cover plate. To install an optic, a MOS 3 adapter plate set from Umarex is required, allowing compatibility with popular footprints such as RMR, Docter, and Vector Frenzy.

Ideal for CQB, Training & MilSim

With realistic dimensions and weight, the Glock 45 Gen5 MOS fits standard Glock-compatible holsters, making it a perfect sidearm for MilSim loadouts, tactical training, and fast-paced CQB games. Its strong blowback, precise hop-up system, and premium construction place it among the top-tier gas airsoft pistols on the market.
