The Steyr GB stands out for its innovative gas-delayed blowback system, fixed polygonal-rifled barrel, and class-leading 18-round magazine. Produced in limited numbers during the 1980s, this Austrian full-size pistol offers smooth recoil management, notable accuracy, and collectibility backed by its short production run and distinctive engineering.

The gas-delayed “Gas-Bremse” (Barnitzke) action vents propellant gas into a separate piston beneath the barrel, slowing slide velocity for reduced felt recoil and reliable cycling with standard 9mm loads.
A fixed 5.3-inch polygonal-rifled barrel contributes to the pistol’s well-known accuracy, while the hard carbon-steel construction and matte phosphate finish provide durability and corrosion resistance.
With a flush-fit 18-round magazine, the GB offered the highest capacity of any service-sized 9mm pistol of its era. The double-action/single-action trigger, slide-mounted decocker/safety lever, and exposed hammer deliver familiar, versatile controls.
Total production is estimated at only 15,000–20,000 units between 1982 and 1988, making surviving examples increasingly scarce. This pistol retains its original importer marks and matching box, enhancing its desirability among Steyr and Cold-War-era collectors.
