Frequently Asked Questions
Glock 19 Gen 4 MOS for sale
Does the Glock 19 Gen 4 have MOS?
Yes, Glock offers the G19 Gen 4 in an MOS configuration. MOS stands for Modular Optic System, which allows a reflex sight to be mounted directly to the slide without a separate adapter plate.
How to tell if Glock 19 is MOS?
Check the slide for pre-cut optic mounting cuts and a removable cover plate. MOS models ship with numbered adapter plates for mounting red dot sights. Standard G19 slides lack these cuts. The box, manual, and Glock's website will confirm the MOS designation.
Can you buy a Glock 19 MOS slide?
Yes, Glock 19 MOS slides are available for purchase. Our marketplace lists 7 variants across 10 retailers, with 3 currently in stock. Prices range from $503.64 to $729.74, with a median around $619.99. These factory optic-ready slides fit MOS frames and support direct red dot mounting.
Is a Glock MOS slide worth it?
Worth depends on your optic choice. MOS adds $100-120 over standard slides and eliminates gunsmith costs. Quality third-party plates work well; Glock's plates get mixed reviews. If you plan to run a compatible red dot long-term, MOS saves money versus aftermarket milling. Rear iron sights forward isn't available on MOS.
Is the Glock 19 Mos discontinued?
The Glock 19 MOS is discontinued. Glock has discontinued both the Gen 4 and Gen 5 MOS versions of the G19, with Glock's own webpage listing the G19 Gen5 MOS as discontinued. This is part of a broader phase-out of Gen 4 and Gen 5 models, replaced by the new Glock V Series.
Is the Glock 19 Mos a good gun?
Whether it's "good" depends on your needs. The Glock 19 MOS is reliable and well-proven, suitable for concealed carry and home defense. The MOS cut allows red dot mounting without gunsmithing. The Gen4 version has been superseded by Gen5, so check availability before purchasing.
What plates does a Glock 19 Mos come with?
The Glock 19 MOS currently ships with one MOS adapter plate. Older production runs included four plates for different red dot footprints, so unboxing videos may show this. Confirm which plate is included with your retailer or Glock directly, and purchase additional plates separately if needed for your specific optic.
What red dot fits on Glock 19 mos?
The Glock 19 MOS accepts red dots via adapter plates, including the Trijicon RMR Type 2, Leupold DeltaPoint Pro, Vortex Venom, and Holosun 507C. The Holosun SCS MOS mounts directly without an adapter plate. Always verify your specific optic's compatibility before purchasing.
