The Glock 17 has gone on to see extensive service in both military and police roles with a plethora of nations around the globe. In its most basic form, the Model 17 was a simple weapon to operate and breakdown, consisting of just over 30 parts to contend with. The pistol was billed as a "recoil-operated, semi-automatic handgun", firing the 9x19mm Parabellum cartridge from a seventeen-shot detachable box magazine. The pistol's appearance was very clean and Glock handguns, in general, have become more of a fixture within security and military organizations around the world. Beyond the 17-shot magazine were optional capacities of 10-, 19- and 33-round counts (not including any chambered rounds).
Other Glock 17 models in the family included the Model 17L of 1988 (which featured and increased barrel length) and the Model 17C of 1988 (which featured a muzzle compensator to assist in accurized shooting). The Glock 17MB was fitted with an ambidextrous magazine catch. The Glock 17T was produced as a training pistol to fire rubber or paint bullets. It was produced in two versions known as the Glock 17T 9mm FX and the Glock 17T 7.8x21 AC - these designations denoting the types of cartridges each version could fire. The Glock 17P was another training model to be utilized in close-in, hand-to-hand fighting education.
The Austrian military designated the Glock 17 as the "Pistole 80" while Norway took to naming the firearm as the "P-80". Sweden handled the Glock 17 as the "Pistol 88". The Glock 17A was made for the Australian market, falling within its new firearm regulations. The Glock 17S was delivered to Tasmania, Israel and Pakistan as well as operators in South America. The Glock 17Pro was a customized form sold only to Finland. The Glock 17DK was a Glock product developed specifically for Denmark.
Historically there were no Glock 1 through Glock 16 models. The Glock 17 model number is derived from the product being the company's seventeenth patent. The model is the most widely-used law enforcement pistol in the world and has been favored by some special forces units including Polish JW Grom and Israeli Shayetet 13.
