Add a Red Dot to Your Gen 5 MOS Glock with Confidence
The Glock OEM MOS Optic Adapter for 9MM/.40S&W is a necessary component to mount optics with the Shield RMSc/Leupold Delta Point Pro (DPP) footprint to your Gen 5 Glock pistols equipped with the Modular Optic System (MOS) cut. Backed by Glock’s trusted craftsmanship, this adapter plate is a factory-original accessory that guarantees compatibility and durability. This plate is unique as you can go with larger windowed optics or go with micro red dots for a smaller package.
Firearm Compatibility
This optic adapter plate is made for double-stacked 9MM/.40S&W Glock MOS Gen 5 pistols such as the 26, 19, 19X, 19M, 19C, 17, 17L, 22, 23, 34, 35, 45, 47, and more. It will NOT fit slimline MOS pistols such as the 43X MOS or 48 MOS, which use a different MOS pattern that only works with the Shield RMSc footprint. While this plate works with the Shield RMSc and Leupold DPP, the 43X MOS and 48 MOS will not due to the longer length of the Leupold DPP and other similar dots.
Optic Compatibility
This optic adapter plate is made to fit the Shield RMSc/Leupold DPP footprint, which luckily lots of companies have started making red dots for. Some of the most popular red dots that use this footprint are the Shield RMS/RMSc, Leupold Delta Point Pro, EOTech EFLX, AT3 Tactical Mini ARO, Sig Sauer Romeo Zero/Romeo X/Romeo 1 Pro, and many more red dots made from so many brands. It would take up this whole page to list all of them.
Durable Construction
Made from high-strength steel, these plates are built to withstand recoil and being banged around in a holster without lose of zero or breakage with the legendary Glock durability.
Secure Installation
The set comes with all necessary hardware, including screws and instructions, making installation straightforward and reliable without the need for additional modifications.
Enhanced Performance
By enabling the use of red dot optics, the adapter plates improve target acquisition, accuracy, and overall shooting performance, whether for tactical, competitive, or defensive scenarios.
