About the Handgun:
The Gen 4 series of Glock pistols were introduced in 2010. Like most new polymer framed pistols the Gen 4 series features interchangeable grip inserts. The Gen 4 series also incorporates a dual recoil spring assembly, a feature only in previous generations' compact models. Other features include a reversable magazine release, a Tenifer matte finish slide and new grip texture. Changes in the Gen 4 design are significant enough such that not all parts can be mixed and matched with previous Glock generations.
About the Manufacturer:
Founded by Gaston Glock in 1963, this precision-engineering business surprised the world in 1983 by winning a contract to provide 25,000 pistols for the Austrian army - having never made a pistol before. This venture met with great success however, and Glock's guns have acquired such a sound reputation for reliability and simplicity that subsidiaries have been opened in the US, Hong Kong and Uruguay. By the year 2000 more than 2.5 million guns had been sold to military and police forces in a hundred countries.
About the Cartridge:
This cartridge was introduced along with the Luger semi-automatic pistol. The pistol and cartridge was first adopted by the German Navy in 1904 and then by the German Army in 1908. This cartridge has since been adopted by the military of practically every non-Communist power. It has become the most popular and widely-used handgun cartridge in the world. Performance wise, the 9mm cartridge has somewhat more power than the .38 Special but falls well short of the .357 Magnum.
