By the 1980s; the Austrian military needed a pistol to replace the World War 2 Walther P38 pistol. They wanted to make a pistol with a criteria list of 17. By 1982; Glock assembled the leading gun experts in Europe and within three months, Glock came out with it's first working prototype of the Glock pistol.

- After firing 15,000 rounds of standard ammunition, the pistol will be inspected for wear. The pistol will then be used to fire an overpressure test cartridge generating 5,000 bar (500 MPa; 73,000 psi) (the normal maximum operating pressure Pmax for the 9mm auto is rated at 2,520 bar (252 MPa; 36,500 psi).The critical components must continue to function properly and be up to specifications, otherwise the pistol will be disqualified.
