To address the growing popularity of optics-ready handguns for competition, hunting and self-defense, Glock introduced the MOS sight system in 2015. The first three models out the door included the Gen4 competition long-slide G34 and G35, and the new 6" barrel 10 mm G40 hunting handgun. For 2016, Glock is expanding the MOS line-up to include two of its most popular 9 mm models, the Standard size Gen4 G17 and Compact G19.

Along with the usual Gen4 accessory set, the new 9 mm MOS pistols will arrive with Glock’s Adapter Set 01, which includes four optics mounting plates, a wrench and mounting screws. The plates allow a variety of optics to be used, including the Leupold Deltapoint Pro 2.5 MOA red dot (shown here with the G17) and the Trijicon RMR 1.0 MOE red dot (mounted to the G19).

Installing an optic is easy to do. After field stripping the pistol, remove the contoured section of the slide by using the provided wrench to loosen the two retention screws. Then select the correct optics mounting plate by pairing the plates with the optic until you find the right fit. Attach the plate to the slide using the short screws included in the MOS package and then attach the optic.

Based on my experience of the MOS system so far, I’m confident the new optics-ready versions of the G17 and G19 will be a popular option with Glock fans.
