Pros & Cons
Pros
Exceptional Durability
Built around the proven RMR concept with rugged 7075-T6 aluminum construction.
Excellent Reticle Versatility
The 3.25 MOA dot works well as a general-purpose aiming point, while the selectable 55 MOA segmented circle offers a faster visual reference.
Top-Loading Battery
Fixes one of the biggest inconveniences of the traditional RMR Type 2—you don’t have to remove the optic for battery replacement.
Improved Window
Larger viewing area than the classic RMR makes tracking the dot easier during recoil and transitions.
Excellent Automatic Brightness System
Forward-facing sensor reads lighting toward the target rather than relying solely on ambient light around the shooter.
Premium Build Appeal
This is exactly the kind of optic that makes sense on a higher-end Glock, Staccato, duty or custom build.
Cons
Expensive
One of the more expensive open-emitter pistol optics.
Still Open Emitter
Unlike the RCR, ACRO P-2 and other enclosed optics, debris can potentially obstruct the emitter.
Larger Than Original RMR
The larger window and forward extension make the HD physically bigger than the classic RMR.
Potential Fit Considerations
Trijicon specifically cautions against mounting it where the optic’s forward section overhangs the chamber/breech face because that can potentially interfere with pistol operation.
