We have used most of them for years, and some for almost a decade to provide this insightful guide.

Trijicon SRO - Largest FOV

The new Trijicon SRO for Glock pistols are extremely easy and fun to shoot. The Trijicon SRO features a large circular shape window for much faster target acquisition and dot tracking.

This is one of the top red dot RMR red dot for Glocks for competition shooting and range use.

Reticles offered are: 1, 2.5 or 5 MOA center dot only

Holosun 507C - Best Overall

The Holosun 507C red dot features the exact same Trijicon RMR footprint to work with all existing RMR cut slides and adapters, and it's one of the most popular RMR alternative today.

Above all, the 507C features side loading battery tray to replace battery without sight removal, a multiple reticle system (32 MOA ring + 2 MOA center dot), or ACSS Vulcan reticle for faster target acquisition.

Solar panel isn't a huge deal since the battery life already lasts more than 4-5 years on a single CR1632 battery.

Cyelee Wolf X Pro - Best For The Money

The Cyelee Wolf X Pro has a larger sight window, and upon my initial trial, I was pleasantly surprised by its increased height compared to the Trijicon RMR and Holosun 507C. In terms of width, it's slightly wider than the Holosun 507C.

This larger window offers a tad more space to capture the reticle if it starts drifting away from the shooter. However, personally, I don't find this aspect to be of great importance, as the difference it makes is minimal.

The Cyelee Wolf X Pro features a 2 MOA central dot along with a 25 MOA ring. In my personal shooting encounters, I greatly preferred the solitary dot because it provides a less cluttered sight picture whether shooting during the day or at night.

Holosun 508T - Titanium Body

Holosun 508T red dot is similar to the 507C but with a slightly different top body profile. It's made of titanium material for improved hood strength.

It also uses the RMR footprint red dot adapter plates.

Swampfox Justice - Tapered FOV

Swampfox Justice is another RMR optic for Glock pistols. This 7075 T6 aluminum body optic is a smaller version of the Kingslayer model, but with a tapered window to increase the FOV up to 1X27mm.

The tapered window design slightly gives the user the feel of an enlarged optic FOV laterally without increasing the optic base width and it still fits any Trijicon RMR cut and mounting plates.

There are two ways to mount an RMR footprint optic on a Glock pistol:

  • Buy aftermarket Glock RMR slide (Must be model specific)
  • Buy an optic ready Glock clone like the Shadow System MR920

Does RMRcc Use The Trijicon RMR Footprint?

No. RMRcc doesn't use the RMR footprint. The two holes on the RMRcc are closer together to fit on subcompact pistol slides
