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.
