Licensed Glock Realism with Gen5 Details
The Umarex GHK Glock 17 Gen5 MOS has been designed to closely replicate the look, feel and handling of the original Glock 17 Gen5 platform. The pistol includes official Glock markings, a realistic profile and dimensions compatible with standard Glock-size holsters, making it a strong choice for players who want a reliable sidearm that also looks right on a tactical belt or plate carrier setup.
Gen5 improvements include ambidextrous controls, a reversible magazine release, a beveled front slide, updated grip texture without front finger grooves and refined sights. These features make the pistol comfortable to manipulate and suitable for both right- and left-handed players.
MOS Optic-Ready Slide
The MOS - Modular Optic System configuration allows the pistol to accept compatible micro red dot sights. The optic cut is protected by a pre-installed cover plate when no optic is mounted. For red dot installation, a compatible Umarex MOS 3 adapter set is required, enabling use with popular optic footprints such as RMR, Docter and Vector Frenzy-style sights.
This makes the pistol an excellent choice for players who want a modern optic-ready Glock airsoft pistol for fast target acquisition in CQB arenas or dynamic pistol-focused gameplay.
GHK Performance Internals
Inside, this pistol benefits from GHK’s premium gas blowback engineering. The reinforced internal parts, redesigned trigger mechanism and new hop-up chamber help deliver smoother operation, efficient gas use and stable shooting performance. The pistol is suitable for Green Gas and Red Gas use, and it is also CO2 ready when used with compatible CO2 magazines.
The strong blowback system gives every shot a realistic recoil impulse and cycles the slide fully, chambering the next BB with an authentic feel. With a muzzle velocity of approximately 95 m/s, the pistol remains below 1 joule, making it suitable for many European airsoft fields where sidearm limits apply.
