The GLOCK 19X® MOS Semi-Automatic Pistol is the semi-auto pistol GLOCK® created as their bid offering for the U.S. military's Modular Handgun System (MHS). The 19X has many of the features of the new Gen 5 series pistols on a full-size, model 17 frame, with a compact model 19 slide and barrel assembly. The full-sized 17-length helps enhance control. The shorter f19-sized slide makes the gun faster to draw with less slide to clear a holster. The slide and main metal components of the 19X feature an ion-bonded, nDLC coating in Coyote brown, for increased protection against corrosion and scratching, and improved ability to function in dry conditions with minimal lubrication. The muzzle end of the slide has been beveled for smooth draw and easier, guided reholstering. The finger grooves have been eliminated on the 19X frame to enhance speed of getting the shooter's fingers into a correct hold. An ambidextrous slide stop lever accommodates both right- and left-handed shooters. A Marksman barrel with polygonal rifling provides exceptional accuracy.
