It is the most popular Glock model, famous for concealed-carry and use by people with smaller hands.
The very similar Glock 17 is the standard-sized model, with a slightly shorter grip and therefore a smaller magazine that accepts up to 15 rounds. A subcompact model with even shorter grip and 10-round magazines, the Glock 26, also exists. It was designed and produced by Glock Ges.m.b.H., located in Deutsch-Wagram, Austria. The company's founder, engineer Gaston Glock, had no experience with firearm design or manufacture at the time their first pistol, the Glock 17, was being prototyped. Glock did, however, have extensive experience in advanced synthetic polymers, knowledge of which was instrumental in the company's design of the first successful line of pistols with a polymer frame. Glock introduced ferritic nitrocarburizing into the firearms industry as an anti-corrosion surface treatment for metal gun parts.
Despite initial resistance from the market to accept a "plastic gun" due to durability and reliability concerns, Glock pistols have become the company's most profitable line of products, commanding 65% of the market share of handguns for United States law enforcement agencies as well as supplying numerous national armed forces and security agencies worldwide. Extremely reliable and durable, as well as being easy to use and maintain, Glock pistols are incredibly popular with civilians and law enforcement alike. Today it is the easiest pistol to disassemble and the Glock is unique in the way that slides can easily be switched from pistol to pistol to allow for different caliber changes. It is also the only pistol that has three seperate internal safeties that engage at once.
