The Glock 20 Gen 5 MOS is a full-size 10mm handgun built around Glock’s Gen 5 design updates and the Modular Optic System slide. The platform is intended for users who require increased ballistic performance while retaining Glock’s standard operating system and reliability envelope. The MOS cut allows mounting of compatible slide mounted optics using adapter plates.

The pistol features the Glock Marksman Barrel for improved consistency, an ambidextrous slide stop lever, flared magazine well, and revised frame texture without finger grooves. The nDLC-finished slide provides enhanced wear and corrosion resistance. Standard Glock controls and the Safe Action striker system are retained, making the G20 MOS suitable for duty, defensive, or backcountry roles where 10mm performance is desired.
