As the capabilities and prices of advanced optics continue to improve, more and more shooters are using them as a matter of course. It was only a matter of time before Glock had to shift gears slightly to make an optics-ready pistol.
The new Gen 4 MOS (Modular Optics System) series of handguns comes with a cover plate that can easily be removed and one of four mounting plates can be installed. Each plate is compatible with a particular mounting method. For instance, one of the plates is designed to work with Trijicon. Another mates with EoTech. Shooters that don’t use optics can simply leave the cover in place for the classic Glock appearance.
