Glock introduced ferritic nitrocarburizing into the firearms industry as an anticorrosion surface treatment for metal gun parts. Glock had extensive experience in advanced synthetic polymers, which was instrumental in the company's design of the first commercially successful line of pistols with a polymer frame. The company's founder, head engineer Gaston Glock, had no experience with firearms design or manufacture at the time their first pistol, the Glock 17, was being prototyped.

Glock is a brand of polymer- framed, short recoil-operated, locked-breech semi-automatic pistols designed and produced by Austrian manufacturer Glock Ges.m.b.H. Short recoil, locked breech, tilting barrel ( straight blowback for Glock 25, 28 and 44)
