GLOCK pistols: test, overview and models

GLOCK pistol are among the most popular and famous guns in the world and are synonymous with exceptional reliability. In the United States, the Austrian manufacturer's firearms are the most popular type of handgun and have heavily influenced the gun market throughout the rest of the world. The success story of GLOCK pistols began in the early 1980s, when Austrian engineer and developer Gaston Glock launched the GLOCK 17, the first GLOCK pistol, onto the market in 1982. Only a year later, this model was adopted by the Austrian army under the name P80 to replace the WWII-vintage Walther P38. GLOCK semi-automatic guns were among the first with a polymer frame and steel inserts. Although GLOCK did not invent the polymer frame – it was Heckler & Koch, with the VP-70 – the development of GLOCK 17 marked a new era in the history of handguns.

Since then, the success of GLOCK has never stopped. In 2007, the company announced that it had sold more than 5 million GLOCK pistols worldwide. Today there is a large range of GLOCK models in 5 sizes, 8 calibers and 5 production generations, and the trend is on the rise. GLOCK pistols in their various versions are highly appreciated not only by the military and LEOs, but especially by sports shooters. Shooters particularly appreciate GLOCK pistols for their excellent ergonomics and impressive accuracy.

P9 A1, GLOCK service pistol

The legendary reliability of GLOCK service guns is and remains unmatched. Safe and easy to use, GLOCKs have been chosen as service guns by special forces, military and government agencies. Approximately two-thirds of US law enforcement agencies, various special forces around the world, as well as the Austrian and Norwegian armed forces, rely on the outstanding quality, reliability and handling of GLOCK pistols, but also on their versatility. A good example is the GLOCK P9 A1, whose striker fire action has considerable advantages in naval use: thanks to its functionality, this semi-automatic pistol can be used by special forces because it's also capable to fire underwater.

The reasons for the success of GLOCK guns are obvious. On the one hand, the simple technology, the ease of use that allows even inexperienced shooters to achieve excellent results, combined with an unmistakable design, to which the company has always stayed true. It is precisely this continuity to contribute significantly to its success. Today's GLOCK handguns still uniquely follow their inventor's ideas: an ergonomic pistol with the simplest possible polymer frame, a high magazine capacity and three automatic safety features.

In addition, the fifth generation GLOCK pistol models are equipped with new sights that provide a much better target image, especially in bad light conditions. But that's not all: GLOCK Gen5 pistols feature the more accurate GLOCK Marksman Barrel (GMB). Finally, the new Gen5 models sport a proprietary surface finish called nDLC, much more scratch and corrosion resistant than previous GLOCK guns.
