Milled slide cutout for optic sights Ion-bonded, nDLC slide coating Flared magazine well No finger grooves Marksman barrel The GLOCK® 19 Gen5™ MOS FS Semi-Auto Pistol comes factory enhanced with a milled slide cutout, Modular Optic System (MOS), for attaching aftermarket optic sights, and front slide serrations (FS) accommodate racking the slide with an optic sight installed. The slide and main metal parts of the Gen5 pistol come with an ion-bonded, nDLC coating for increased protection against corrosion and scratching, and improved ability to function in dry conditions with minimal lubrication. The muzzle end of Gen5 slide has been beveled for smooth draw and snag-less reholstering. The finger grooves have been eliminated on the Gen5 frame to speed the shooter's ability to get fingers into a correct grip, and a flared magazine well speeds reloading in high-stress situations. An ambidextrous slide stop lever accommodates both right- and left-handed shooters. A Marksman barrel provides exceptional accuracy. Several small internal modifications were made on the Gen5 to enhance reliability. Rough textured frame surface (RTF) on the polymer frame provides a sure hold on the pistol when hands are wet or sweaty, and the enlarged magazine catch is reversible. An integral accessory rail in front of the trigger guard allows for the attachment of a plethora of aftermarket tactical accessories. The GLOCK 19 Gen5 MOS FS Semi-Auto Pistol features the simplicity and reliability that have made GLOCK semi-automatic pistols a favored sidearm for law enforcement, military, and civilian use all over the world.
