The Glock 19 is a smaller pistol (defined as "compact") based on the original Glock 17 with the new gun made easier to conceal for use by military and police forces. The pistol was debuted by Glock GmbH of Austria in 1988. When compared to the Glock 17, the Glock 19 retained the weight to its slide to keep the short recoil operation in check while at the same time shortening the grip and barrel. Many of the components of the Glock 19 were made interchangeable with the Glock 17 and this included the magazine. Essentially, the Glock 19 was the same design, just made more compact.
Externally, the Glock 19 was of a conventional design. The squared-off slide was a defining feature of all Glocks as was the squared-off trigger guard. Sights were positioned at the extreme ends of the slide, mounted fore and aft. The grip featured an ergonomic hold and the magazine inserted into the grip base, it holding up to fifteen 9x19mm Parabellum cartridges. Total length of the weapon was 6.85" with the barrel measuring 4" inches in length. Unloaded weight was 21 ounces. Other magazine capacities made available were 10-, 17-, 19- and 33-round counts.
The Swedish Army took delivery of the Glock 19 in 1990, designating these pistols as "Pistol 88B".
In 2015 it was announced that the Glock 19 would supersede the Sig 226 pistol as the standard sidearm of the United States Navy SEALs. The gun is also in use by MARSOC units (MARrine corps Special Operations Command).
