About the Glock G19 Gen4 MOS

The Glock G19 Gen4 MOS is a semi-automatic pistol chambered in 9x19mm Parabellum, produced by Glock Ges.m.b.H. since 2015. This Austrian-manufactured firearm reflects the engineering traditions and quality standards of its country of origin, designed to meet the demands of both civilian and professional users in a competitive global marketplace. Featuring a 15-round magazine capacity, this pistol offers generous firepower for duty use and home defense. The striker-fired action provides a consistent trigger pull for every shot, simplifying training and reducing the manual of arms - a design philosophy that has become the dominant paradigm in modern defensive handguns. The 4.0-inch barrel provides an excellent balance between sight radius and portability, making it equally suitable for duty carry and recreational shooting. Weighing 600g (21.2 oz) empty, this firearm strikes a practical balance between manageable carry weight and sufficient mass to moderate felt recoil during shooting. The polymer frame construction reduces weight while providing a textured, ergonomic grip surface designed for secure handling in all conditions. This firearm represents its manufacturer's commitment to delivering a well-engineered, reliable product that serves the needs of discerning shooters seeking quality, accuracy, and dependable performance from a proven platform.

Founded in 1963, Glock Ges.m.b.H. has built a reputation in the firearms industry through consistent innovation and quality, earning the trust of shooters who demand reliability in their chosen defensive and sporting firearms.

The Gen4 MOS G19 was popular with law enforcement and concealed carry users looking to add red dot sights without aftermarket slide milling. Ships with multiple adapter plates for common optic footprints. The compact slide leaves less surface area for the optic cut compared to the full-size G17 MOS, but accommodates all standard micro and full-size reflex sights via the adapter plate system.

This is a variant of the Glock G19 Gen4.
