Umarex GHK Glock 45 Gen5 MOS GBB Gas Pistol - Black

Umarex Glock 45 Gen5 MOS GBB Airsoft Pistol

This authentic replica of the Glock 45 Gen5 MOS features a durable metal slide with Glock markings and a functioning blowback system that provides a realistic slide movement with each shot, chambering the next round just like the real firearm. Despite its realism, it remains a gas-powered airsoft pistol, offering comfortable and precise shooting. Its dimensions and weight closely resemble the real firearm, fitting securely in standard Glock holsters of the corresponding size category. Umarex produces this replica with a polymer frame and ergonomic design, ensuring a comfortable grip for all shooters. This pistol is an excellent choice for those seeking the realistic design of Glock combined with exceptional performance thanks to premium internal components from GHK. The internal parts, including the trigger mechanism, are designed for use with high-pressure gases like CO2. It also features a newly redesigned trigger mechanism for smoother operation and a new hop-up chamber with quick adjustment. An optional CNC 4UAD hop-up chamber is also available for upgrades. The pistol is compatible with GHK Glock 17 Gen3 magazines, including CO2 variants.

What Improvements Does the Gen5 Offer Over Gen4?

• Fully ambidextrous controls (slide catch and reversible magazine release).
• Beveled front slide (similar to G26 Gen3/4).
• Removed finger grooves on the grip's front.
• New surface finish.

Umarex/GHK Gas Pistols

GBB gas pistols from Umarex combine realistic details of authentic Glock pistols with refined internal components from GHK, offering premium internals suitable for competitive shooting.
That's why these pistols are often labeled as Umarex GHK Glock. German company Umarex, founded in 1972, specializes in air weapons and holds official licenses from renowned manufacturers like Glock, Heckler & Koch, and Beretta. Their airsoft replicas are highly sought after by Mil-Sim airsoft enthusiasts and regular players due to their durability, reliability, and excellent performance without the need for modifications. Umarex Glock Perfection pistols are among the most accurate airsoft replicas of Glock firearms.
Umarex/GHK Glock offers gas pistols in two power types: traditional gas (Green Gas, Red Gas) and CO2 cartridges.
CO2 versions are generally more powerful but cause more wear on internal parts. Gas-powered variants are more sensitive to cold temperatures (use Red Gas in colder weather). The slide moves its full length like the real firearm.
Generation 5 includes high-quality metal hop-up chambers with GBB/VSR-style bucking, reinforced polycarbonate nozzles with excellent seals, and improved gas flow.
