Gaston Glock originally called it the G17 after its patent. The P80 designation was given to the pistol by the Austrian Military.The actual prototype G17 was originally referred to as the P80, but as Vol said, it was officially named the Glock 17 due to being the 17th patent by the Glock company. Prior to making pistols, they made entrenching tools and plastic training grenades for the Austrian military. They also made shower curtains and other items.
The P80/G17 was designed and produced in response to the Austrian military holding trials for a new pistol.
