Notes
The MOS (Modular Optic System) was introduced in 2015 across several Glock models. The Gen4 MOS includes adapter plates for Trijicon RMR, Leupold DeltaPoint Pro, C-More, and Docter/Noblex footprints. The taller MOS sights provide a slightly longer sight radius (170mm vs 165mm) to allow co-witnessing with mounted optics. Weight is identical to the standard Gen4 as the slide material removed for the optic cut is negligible.
