Glock 17 is the 9mm Luger model of Glock polymer receiver safe action semi-automatic pistol invented by Austrian Gaston Glock. The Glock 17 is the most popular law enforcement handgun in the world.
Glock's G17 fires a 9mm Parabellum round, uses the Glock Safe Action system. The Glock 17's fire power is a 17-round standard capacity magazine (which gun control advocates mistakenly call a "high capacity magazine")
Glock's G17 model of pistol was first developed in the early 1980s to replace the Walther P38 service pistol in the Austrian army. Since then, the Glock 17 and its other caliber variants have become quite popular as military and law enforcement firearms, being exported in more than 50 countries.
The Glock 17 has a metal slide and a polymer receiver. The Glock 17 has a unique safe action mechanism and, unlike most handguns, do not have any external safety on/off lever. No external safety lever means that there is no risk of the shooter either forgetting or not realizing that the safety is on during a threat or emergency situation. The Glock handguns are prevented from being fired accidentally by the user by a triple safety system, dubbed the safe action trigger by Glock. The safe action mechanism includes a drop safety which prevents the handgun from firing if dropped.[1]
