Top Product List: Best Red Dot for Glock 19 MOS Gen 5 of 2025
Here’s my quick summary of the top performers for your Glock 19 MOS Gen 5:
1. Trijicon RMR Type 2

The Trijicon RMR Type 2 is a gold standard among pistol optics — built for military-grade reliability, extreme recoil endurance, and a crisp reticle. The RMR Type 2 is designed to fit Glock MOS slides perfectly with the correct mounting plate.
Specs:
- Reticle: 3.25 MOA red dot
- Battery Life: 4 years (CR2032)
- Housing: Forged aluminum
- Waterproof: Up to 20 meters
- Weight: 1.2 oz
My Experience: I’ve personally run the RMR Type 2 on my Glock 19 MOS Gen 5 through over 3,000 rounds. The sight has zeroed flawlessly and maintained accuracy even after repeated cleaning and slide removal. Its auto-adjust brightness is quick to respond under sunlight and indoor ranges alike. The buttons are tactile yet recessed to avoid accidental presses.
What Users Say: Reddit users consistently praise the RMR Type 2 for its reliability: “Still holds zero after 2 years of EDC carry” is a frequent comment. Some mention a steeper price tag, but virtually no one questions its durability.
Mounting: The RMR mounts directly to Glock MOS using the RMR plate (included with MOS models or sold separately).

2. Holosun 507C X2

The Holosun 507C X2 blends modern tech, solar power, and rugged construction. It’s a direct RMR footprint optic, making it one of the easiest red dots to mount on the Glock 19 MOS Gen 5.
Specs:
- Reticle: 2 MOA dot + 32 MOA circle (multi-reticle system)
- Battery Life: 50,000 hours (solar + CR1632)
- Material: 7075-T6 aluminum
- Brightness Settings: 12 (2 NV compatible)
My Experience: Switching between the circle-dot and single dot reticle is a game-changer for fast acquisition. In my testing, the 507C’s solar backup kept it running even when I forgot to turn it on. The side battery tray simplifies maintenance.
User Feedback: Holosun dominates Glock forums for its performance-to-cost ratio. One user described it as “RMR-level quality at half the cost.” A few noted a blue tint, but it’s barely noticeable during rapid target transitions.
Mounting: RMR footprint; fits Glock 19 MOS directly with RMR plate.

The Leupold DeltaPoint Pro is a veteran in duty optics — known for its large window and crystal-clear glass. It’s perfect for shooters who want faster target transitions and a wide field of view.
Specs:
- Reticle: 2.5 MOA red dot
- Battery Life: Up to 300 hours
- Housing: Aircraft-grade aluminum

My Experience: I’ve used the DeltaPoint Pro on my Glock 19 MOS for both defensive and competition settings. The large window gives excellent visibility, and the MST feature helps conserve battery while still powering on instantly when moved.
Community Opinions: Reddit and GlockTalk users rave about its glass clarity. However, some users mention its slightly higher mounting profile compared to RMR-style optics.
Mounting: Requires a Glock MOS DPP plate for direct mounting.

Swampfox’s Justice RMR has quickly become a fan favorite for budget-conscious Glock owners who want a reliable, high-performance optic.
Specs:
- Reticle: 3 MOA red dot
- Battery Life: 5,000 hours
- Material: 7075 aluminum
- Brightness Settings: 10 manual levels
My Experience: I was impressed with how well the Justice held zero during recoil testing. The window size is generous, and the glass is remarkably clear for the price. It’s not as refined as Trijicon or Leupold, but for under $300, it’s a steal.
Online Reviews: Users on r/Glocks mention “flawless function for EDC” and “comparable to optics twice its cost.” One user highlighted its strong coating and simple battery swap design.
Mounting: RMR footprint — mounts directly to Glock MOS RMR plate.
