The Steyr GB, a 9mm Para pistol, features an advanced gas-delayed blowback system ('Gasbremse') for recoil mitigation. This system uses vented gas from a ported barrel to slow the slide's rearward movement. The pistol has a DA/SA trigger, a decocker, and a unique 18-round double-stack, double-feed magazine. Its construction involves stamped and welded steel 'clamshell' frame pieces, a polymer trigger guard, and a rugged finish. Developed from early 1970s patents, it arrived late to the commercial market in 1981, quickly being outpaced by competitors.
