Special Features
- Factory Glock engineering gives the Glock MOS Adapter Plate 02 (74009) a precise interface with MOS slides, which supports repeatable zero and solid engagement under regular duty or training use.
- RMR footprint layout on this plate lets you mount popular Trijicon RMR and SRO optics on Glock 17, 19, 45, 47, and 34 MOS pistols without custom slide milling.
- Support for Ameriglo and select Holosun RMR footprint optics expands your choices beyond Trijicon, while keeping everything within Glock’s MOS factory mounting system.
- Black finish matches OEM Glock slide finishes so the adapter plate blends into the pistol and keeps the overall optic installation visually clean.
- Included hardware simplifies installation with the correct length mounting screws, so you can focus on torque settings and sight alignment instead of chasing compatible fasteners.
Practical Benefits
- The Glock MOS Adapter Plate 02 (74009) lets you equip compatible Glock MOS pistols with Trijicon RMR or SRO style optics, which supports faster sight acquisition for defensive carry, duty use, and competition stages.
- Because it works with common MOS models like the Glock 17, 19, 45, 47, and 34, this plate helps you standardize an RMR footprint optic across multiple pistols while keeping holster and handling characteristics familiar.
- Direct mounting to the MOS slide keeps your red dot lower than many aftermarket stack-up solutions, which supports a natural presentation, easier dot tracking, and simpler backup sight setup when paired with appropriate iron sights.
- If you want a straightforward way to mount an RMR pattern optic on your compatible Glock MOS pistol while staying within the OEM system, the Glock MOS Adapter Plate 02 (74009) is a reliable pick for secure, repeatable optics mounting.
