Gaston Glock’s strong suite is with synthetic polymers, but he also introduced the gun world to ferritic nitrocarburizing for corrosion protection of metal parts, which is now a staple of the industry. Though he had no experience with firearms, he was able to obtain 17 patents by the time he entered the Glock 17 in the Austrian Army’s testing. The G17, named because of those 17 patents, outperformed offerings from Heckler & Koch, SIG Sauer, FN Herstal, and Austria’s own Steyr Mannlicher. After successes in Austria, worldwide interest piqued in the first successful production polymer pistol and orders rolled in. As a result, the G17 became a standard NATO-classified sidearm, worn by countless Allied soldiers.
