Which Holosun Optics do we recommend for the Zev OZ9/OZ9c?
Why do we recommend Holosun Optics vs other options?
- They are a good combination of high quality and affordability.
- They have the longest battery life and batteries can be changed without removing the optic.
- They come in red & green reticles with different sizes and styles.
- They are strong with 7075 aluminum or titanium housings and glass.
- They have convenient features like Shake Awake, easy to press brightness buttons, and Side Mounted Batteries.
- Some models have Solar Panels which will power the optic if the battery dies.
- They have a Limited Lifetime Warranty.
- They are reliable, water proof, and have a great track record
When you compare them to other options like Leupold, Trijicon, Crimson Trace, Burris, Bushnell, Aimpoint or others you will find the Holosun’s are more affordable or have more features, longer battery life, and a proven track record with millions of optics sold in the last 10+ years.
What optics footprint is the Zev OZ9/OZ9c?
The Zev OZ9 and OZ9C feature an optics ready slide with an RMR footprint with screw posts. This means all the Holosun RMR footprint optics will fit EXCEPT the 509T and 509 ACSS Vulcan. This is because the screw posts get in the way of their clamping system.
Best RMR Footprint Holosun Optics for the Zev OZ9/OZ9c
Below are the best Holosun RMR Footprint optics that will fit on the Zev OZ9 or OZ9c mounting directly on the slide.
1. Holosun 407C Green & Red Dot - Best Budget Option
Buy the 407C At The Best Price
The most budget friendly option is going to be the 407C. The 407C has a 2 MOA dot only. The housing is aluminum.
If you are ok with having just a 2 MOA dot all the time, then the 407C is a great option.
It has shake awake, a side removable battery, solar failsafe with auto brightness or manual brightness modes, 10 daylight and 2 nightvision settings, and is IP67 waterproof.

2. Holosun 507C Green & Red Dot - Best All Around Option
Buy the 507C At The Best Price
The Holosun 507C is very similar to the 407C except it has Holosun "MRS" reticle.
It's available in Red or Green reticles and the MRS (Multi Reticle System) lets you use a 32 MOA ring + 2 MOA dot, or it can be toggled to show only the 32 MOA Ring or just the 2 MOA dot by holding down the "-" button for 3 seconds.
It has shake awake, a side removable battery, solar failsafe with auto brightness or manual brightness modes, 10 daylight and 2 nightvision settings, and is IP67 waterproof.

3. Holosun 507C ACSS Vulcan Green & Red Dot - Best Specialty Option

The 507C ACSS Vulcan may pique your interest. It's just like the 507C except is has the ACSS Vulcan reticle. This reticle features a 250 MOA Ring and a 10 MOA chevron - sounds crazy right? Well it's crazy awesome! It helps new red dot shooter and experts alike, and allows for the most precision out of all optics mentioned here.
You can learn more about the ACSS reticle here but to summarize, the 250 MOA Ring helps you find the center dot quickly if you are off center and the 10 MOA chevron acts like a BDC reticle and also has a very precise point for precision work.
It's available in Red or Green reticles and if you wanted to turn the outside ring off you can by holding down the "-" button for 3 seconds.
It has shake awake, a side removable battery, solar failsafe with auto brightness or manual brightness modes, 10 daylight and 2 nightvision settings, and is IP67 waterproof.

4. Holosun 508T Green & Red Dot - Most Durable Open Emitter

Next on the list is the Holosun 508T. It's very similar to the 507C except it has a stronger housing made out of titanium and a square window that's a little bigger.
The 508T's square titanium housing is made to give it extra durability, both from the shape and the material.
It's available in Red or Green reticles and they come with Holosun's Multi Reticle System, which is a 32 MOA ring + 2 MOA dot, and can be toggled to show only the 32 MOA Ring or just the 2 MOA dot by holding down the "-" button for 3 seconds.

5. Holosun 507 Comp Green & Red Dot - Largest Window Competition Reticle
Buy the 507 Comp At The Best Price
Next on the list is the Holosun 507 Comp. This is one of the newest and most sought after optics from Holosun. Comp stands for "Competition" because this optic features a VERY large window, meant for competition shooting. It's the largest window in the industry.
The 507 Comp has some key differences vs the other optics listed here. First it has the C.R.S. which is the Complete Reticle System. This gives it many reticle configurations like a 2 MOA Dot only or a 2 MOA dot + 8 or 20 or 32 MOA Circle or just a 8 or 20 or 32 MOA Circle.
The 507 Comp also does not have a solar panel on it which means there is also no auto brightness setting.
It has a 7075 aluminum housing, shake awake, a side removable battery, manual brightness modes, 10 daylight and 2 nightvision settings, and is IP67 waterproof.
This is a large optic.

6. Holosun 407C-X3 – Updated RMR Duty Optic
Buy the Holosun 407C-X3 At The Best Price
The Holosun 407C-X3 is the newest evolution of the popular 407C series, bringing several design improvements over the previous X2 model while maintaining the proven RMR footprint that fits most full-size pistol optic cuts and adapter plates.
The X3 version features a flatter top housing designed to improve durability and impact resistance compared to the rounded design of the earlier model. The optic also uses a blacked-out Holosun logo for a cleaner, more subdued appearance.
The optic sits approximately 1mm lower than the previous X2 version, giving a slightly lower deck height which can improve co-witness potential and overall presentation on many pistols.
The 407C-X3 uses a simple and effective 2 MOA dot reticle available in Red, Green, or Gold, providing precise aiming while still remaining fast to acquire.
Battery life has also been significantly improved. Powered by a CR1632 battery, the 407C-X3 delivers up to 100,000 hours of runtime on the dot setting at brightness level 6, roughly double the battery life of the previous X2 generation.

Buy the Holosun 407COMP At The Best Price
The Holosun 407COMP delivers the same large competition-ready housing as the popular 507COMP, but with a simplified reticle designed for shooters who prefer a clean aiming point. It is also the most budget-friendly competition-style optic in Holosun’s lineup, coming in at a lower price than the 507COMP and 507PROMAX.
Built on the RMR footprint, the 407COMP fits a wide range of full-size pistol optic cuts and adapter plates while maintaining a low-profile mounting setup.
The optic features a large competition viewing window, giving a wide sight picture that makes it easier to track the dot during fast target transitions and recoil.
Instead of Holosun’s Competition Reticle System used on the 507COMP, the 407COMP uses a simple and effective 6 MOA dot. The reticle is available in Red, Green, or Gold, offering a bold aiming point that is easy to see during fast shooting.
Power comes from a side-loading CR1632 battery tray, allowing battery replacement without removing the optic or losing zero. Battery life is rated up to 50,000 hours on the dot-only setting.

9. Holosun 507PROMAX – Largest Competition Window Optic
Buy the Holosun 507PROMAX At The Best Price
The Holosun 507PROMAX is designed for shooters who want the largest possible viewing window on a pistol optic. With a window size of 1.18 × 0.98 inches, it offers roughly 21% more viewing area than the 507COMP, making it the largest pistol red dot window currently available.
Built on the RMR footprint, the 507PROMAX fits a wide range of full-size pistol optic cuts and adapter plates while maintaining a secure, competition-ready mounting setup.

The reticle is available in Red, Green, or Gold, allowing shooters to choose the reticle color and style that best fits their shooting preference or match environment.
A forward-leaning integrated sunshade helps reduce glare and improves reticle contrast in bright lighting conditions, while the enlarged window makes it easier to track the dot during fast transitions and recoil.
The 507PROMAX also features a solar panel unlike the 407COMP and 507COMP, which gives it Solar Failsafe and an auto brightness mode.

Choosing between Red or Green Reticles
You may be wondering if you should get a red or green dot reticle. We get this question a lot so I am going to list a few bullet points for you to consider.
- Green reticles are less straining for the eye to see.
- Green reticles can help with astigmatism. If you have astigmatism you will see a blurry dot, we have been told by a few customers that Green dots help with their astigmatism, making the dot look more crisp than the red version.
- Green will not washout on backdrops like green grass, foliage, or green colors.
- In theory Green dots can have a longer battery life because Green is brighter, so for example a green dot on brightness setting 6 may be the same brightness as a red dot on setting 7 - which would save battery life.
If you want to learn more check out our full article about Red vs Green Dot Pros & Cons here.
Choosing between Open vs Closed Emitters
The simplest way we can break down open vs closed emitters is to look at how you plan on carrying the pistol. If you plan on being outdoors in the elements with rain, snow, sleet, then a closed emitter will be beneficial.
If you plan on carrying OWB most of the time and plan on being outside then closed emitter would be beneficial.
If you plan on carrying IWB or don't plan on being outside using your red dot in the pouring rain or heavy snow then an open reflex is fine.
Open reflexes will still work in the rain or snow but the closed emitter will give you extra peace of mind.
An open reflex can collect dust and debris on the inside of the reticle over time, so you'll want to clean it out from time to time. An enclosed emitter is easier to clean in this aspect.
