Trijicon RMR RM07 - Best Overall

trijicon rmr on mr920

When To Pick RMR Over Holosun 507C ? - Holosun 507C is great, but nothing beats an American made product. The RMR is much stronger and slightly more compact for conceal carry.

RMR has everything a rugged optic should be. In many ways the Holosun 507C has many user friendly features, but the RMR is the original battle proven micro red dot serious professionals use!

The type 2 models are built specifically for handling G force on handgun slides with a much tighter battery grip so recoil doesn't loosen the electrical connection.


  • Battle proven durability
  • Better battery grip tightness
  • Co witness with iron sights


  • Open emitter attracts debris easily
  • Sight removal required for battery swap

Holosun 507C X2 - Best For The Money

best red dot sight for MR920

The Holosun 507C X2 offers great value for its price. It has many features and benefits that may not be necessary for everyone looking for an slightly more affordable optic with good quality over the RMR. 

For example, the 32 MOA ring may not be useful for some users. But the brand listens to serious end-users, and their products push other companies to be more affordable, rugged, and have more features.

Improved Sight Alignment - Slightly larger window than the RMR, aim with both eyes open on the Shadow System MR920 just like other Glock MOS pistols.

Uses RMR Footprint - Shadow System MR920 slides are made for the RMR footprint right out of the box

Battery Almost Doesn't Run Out - 50,000 hours of battery life plus solar panel backup power. This thing last so long you might forget it has a battery in it.

    trijicon sro on mr920

    The SRO by Trijicon is an interesting optic that features a big glass clear window, easy adjustments, and a top-loading battery. However, It may not be the best choice for those who often drop their gun or land on their holster first. Yet, it has a lot of features and benefits that may be suitable for some competition shooters.

    On Target Every Time - Large circular window helps shooter acquire the dot every time even with slightly off alignment or imperfect draw presentation 

    Easier Battery Access - Swap battery right from the top without sight removal like the Leupold DeltaPoint to reduce long term wear on the mounting screws and threads

    Larger Reticle Options - Available for 1 MOA, 2.5 MOA, and 5 MOA. 5 MOA works the best for shooters with astigmatism.

    Same RMR mounting footprint - Same mounting footprint as RMR and Holosun 507C (No special plate needed)

    Reticle Lockout Mode - Saves reticle brightness setting to prevent accidental adjustments.

    • Magnification: 1x
    • Dot Color: Bright Red

    • Increased FOV for dot tracking
    • Lockout mode built in
    • Same RMR footprint
    • Top battery access


    • Not for CCW
    • 6 MOA or 8 MOA not offered currently

    I recently checked out the Cyelee WOLF X Pro Compact Red Dot, and it's compatible with RMR/SRO red dot footprints. One thing I love about it is the Shake Awake motion-sensing tech. If I'm not using it, it goes to sleep in 5 minutes, saving battery. But as soon as I move it, it wakes up - super handy!

    The 3 MOA Red Dot is a game-changer for quick target locking and precise shots. I'm also impressed by its durability; the aircraft-grade aluminum can handle daily wear and tear. The view through the multi-coated glass is crystal clear, and the red dot stands out with 10 brightness levels. It's even got settings for super bright conditions.

    Plus, it comes with an optional Picatinny mount adapter, perfect for rifles or shotguns. And I've heard it's tested for extreme weather, so whether it's rain or snow, it should work just fine.

    • Material: 7075 T6
    • Dot Size: 3 MOA +  26 MOA Ring

    The DeltaPoint Pro 6 MOA perfect fits the pre-milled footprint on the MR920 slide. The DPP optic now offers a large size 6 MOA model for pistol shooters.

    The field of view is larger than RMR and similar to the SRO. This old school red dot is one of the top choices.

    Extra Housing Protection - Secondary lens hood diverts physical impact completely away from the main glass frame to prevent shattering

    Built In Motion Sensor - Saves battery juice when sitting at rest. It activates when sensing motion when the user picks it up.

    Easier Battery Access - Swap battery right from the top like the Trijicon SRO without sight removal! This is a top rated feature many good red dot sights have

    Swampfox Justice - Tapered Large FOV

    Why we picked this one - The Swampfox Justice uses the same RMR footprint but with a larger than RMR field of view. It's an unique FOV profile that deserves a try!

    Shake Awake - It's the same motion sensor technology as the Holosun 507C

    Track The Dot Better - The FOV gets larger on top of the optic frame to create more window room to find the dot
