Back in January 2015, Glock introduced their MOS (Modular Optic System) system to the world with awesome reviews. The MOS system allows for different optics to be easily added to the firearms, and was first available on Glock models 34, 35, 40 and 41.
Now, we’d like you to meet the two newest members sporting the MOS look and functionality: the Glock 17 Gen4 MOS and the Glock 19 Gen4 MOS.
Press release to follow but in the meantime, enjoy the pictures below and hands-on video at the top of the page.
