The Glock 19 Gen4 MOS is one of the the Modular Optic System (MOS) series Glock pistols. The MOS is offered with a cover plate when no optic is mounted and four different plate options to comply with the specifications of some of the most trusted optic manufacturers in the industry. With the reflex optics, you look through the reticle and focus on the target and alignment of the dot. With standard iron sight shooting, you align the front and rear sight with a hard focus on the front sight.
