GLOCK Modular Optic System (MOS) Configuration
GLOCK engineers have developed the Modular Optic System (MOS) configuration to simplify mounting of popular optical sights.
Optical sights improve the accuracy at both long and short range, enabling faster target transition and quicker sight acquisition of your target. The MOS configuration is the best choice to hit your target.
The Slimline MOS pistol models have slide cuts designed for specific micro-optics and do not need Adapter Plates.
GLOCK Gen5 pistol models in standard MOS configuration will come with one GLOCK MOS Adapter Plate. If your selected optic is not compatible with Adapter Plate 02 and 06, additional options are available on the GLOCK Shop.

What’s the difference in reflex optics and standard iron sights?
Reflex Optics: You can look through the reticle and focus on the target and alignment of the dot. Optical sights are popular in competitive shooting and are becoming increasingly common for home defense and target shooters.
Standard Sights: You must align the front and rear sight with a hard focus on the front sight.
What’s the importance of dot size?
Large dots: Easier to see in close range and bright light situations.
Small dots: Better for long distance targets and low light situations.
