GLOCK, Inc.'s new Modular Optic System (MOS) was designed by GLOCK engineers to enable users to mount their preferred reflex sights to their pistol in order to improve their target acquisition. The Gen4 models G34, G35, and G41 will now be available in the new MOS platform. Coming soon is GLOCK 40 Gen4 in MOS Configuration – the long slide pistol is intended for 10mm enthusiasts as well as handgun hunters.
The MOS models include an Adapter Plate Kit containing 4 adapter plates as well as the tools for the removal and installation for a variety of optics. Optics are not included with the MOS pistols.
The specifications for the Gen4 MOS configured G34, G35, and G41 are the same as their respective non-MOS versions.
