GB introduced in mid-1970s as a 9mm Parabellum military pistol. Large in size, with 18-round magazine capacity. Other features included polygon rifling and gas trap around barrel to delay breech opening. Initially produced as Rogak P-18 by L.E.S. of Morton Grove, Illinois. Discontinued due in part to quality control problems. Just over 2,000 made. Later production by Steyr as GB was to much higher standards, but GB never achieved much popularity and discontinued in 1988.
