The models that may be ordered in the MOS configuration are the G17 Gen4, G19 Gen4, G34 Gen4, G35 Gen4, G41 Gen4 and G40 Gen4 MOS. Specifications of these models do not vary from their respective Gen4 configurations.

Clarity - Quicker sight acquisition of your target.
Speed - Faster target transition.
Versatility - The modular optic system gives you the option of adding tall iron sights that allow the optic and iron sights to co-witness providing backup in the case of optic failure.
Accuracy - Improved accuracy at both long and short range.

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.

The GLOCK MOS allows the shooter to mount the sight of their choice, easily and quickly using only a few tools. The versatility of the system makes changing optics easy. Switching from one sight to another is as simple as removing the old sight, removing and reinstalling the correct adapter plate, then mounting the new sight.
