One of the most compelling attributes of the GLOCK pistol is its simplicity. The GLOCK 17 pistol has only 34 parts total. Unlike most every other handgun made before 1982, the P80 sported no external switches.
The P80 was not technically the world’s first polymer-framed pistol, nor did it pioneer the striker-fired trigger. The Heckler and Koch VP70 machine pistol featured both more than a decade earlier. However, as the trigger pull on the VP70 was measured in metric tons, that abortive rascal was just too much too soon.
