The new model has been requested by our user: Steyr GB pistol The GB is a blowback-operated, gas-retarded blowback semi-auto pistol. It uses some of the hot powder gases, feeds from the barrel into the front part of the slide, to slow down the retraction of the slide before the bullet leaves the barrel.
