Top 5 Best Red Dot for Glock 19 MOS Gen 5 of 2026
1. Trijicon RMR Type 2 – Best Overall Duty Red Dot
The Trijicon RMR Type 2 remains the gold standard for the Glock 19 MOS Gen 5. Built from forged aluminum and proven in military applications, it combines unparalleled toughness with crystal-clear optics.

Pros
Cons
My Experience
I’ve used the RMR Type 2 on duty Glocks and in three-gun matches—it simply refuses to fail. The tactile clicks and firm detents in windage adjustments make sight-in straightforward, and it survives recoil from +P loads effortlessly.
Mounting: Direct fit to Glock MOS with RMR plate (included on newer models).
2. Holosun 507C X2 – Best Value for Everyday Carry
The Holosun 507C X2 offers exceptional performance for the price. It shares the same footprint as the RMR but adds solar fail-safe power and a multi-reticle system.

Pros
Cons
Personal Experience
Mounted on my Glock 19 MOS, it held zero after 1,500 rounds of Speer Gold Dot. The auto-brightness adjustment is smart enough for transition from daylight to low-light without blooming.
Mounting: Direct fit using Glock RMR MOS plate.
3. Leupold Deltapoint Pro – Best for Competition and Precision
The Leupold Deltapoint Pro is a competition shooter’s dream—its expansive window and pinpoint clarity make target transitions lightning fast.

My Experience
On my Glock 19 Gen 5 MOS, I used this in an IDPA competition—the sight picture clarity under bright sun was unmatched. The top-loading battery is an ergonomic advantage.
Mounting: Use Glock MOS Deltapoint plate (sold separately).
4. Vortex Defender CCW – Best for Concealed Carry
The Vortex Defender CCW is purpose-built for carry guns like the Glock 19 MOS. Compact, rugged, and backed by Vortex’s lifetime warranty, it’s an ideal choice for EDC users.
