Which Holosun Optics do we recommend for the Masada Slim 9S?
|
|
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 Masada Slim 9S?
The Masada Slim 9S features a modified RMSc footprint a.k.a. Holosun K Series footprint. This means all the Holosun K Series optics will fit on the slide with no adapter plates or modification needed.
We love seeing this and congratulate the team at IWI for making the Masada Slim 9S come with a modified RMSc footprint vs the standard RMSc footprint and it allows for more options.
Best Modified RMSc Footprint Holosun Optics for the Masada Slim 9S
Below are the best Holosun Red & Green dot sights you can mount directly on your IWI Masada Slim 92 Optics Ready version with no modification necessary.
1. Holosun 407K Green & Red Dot - Best Budget Option
Buy the 407K At The Best Price
This is the most affordable micro optic Holosun makes and is available in a 6 MOA green or red dot.
If you are looking for a single dot optic that is very affordable and great for plinking then this might be the one for you.
The 6 MOA dot is a really nice size. It's big enough to pick up rather easily, but still small enough to be precise with.
It has an aluminum housing, side removable battery, manual brightness controls, shake awake, is IP67 waterproof, and 50,000hrs of battery life.

2. Holosun 507K Green & Red Dot - Best All Around Option
Buy the 507K At The Best Price
The next step up from the 407K is the 507K. This has all the same features like an aluminum housing, side removable battery, manual brightness controls, shake awake, IP67 waterproof, and long battery life but it also has Holosun's Multi Reticle System (MRS).
The MRS Reticle is a 32 MOA Ring with a 2 MOA dot. It's really cool when you look at it - it's similar to an EOtech's reticle if you've ever seen them.
The other cool thing is you can toggle the reticle holding down the "-" for 3 seconds. So if you wanted to, you could use just the 32 MOA Ring, the 2 MOA Dot only, or both the 32 MOA Ring + the 2 MOA Dot.

3. Holosun 507K ACSS Vulcan Green & Red Dot - Best Speciality Option
Buy the 507K ACSS Vulcan At The Best Price
Next on the list is the 507K ACSS Vulcan. This is exactly like the 507K except is has the ACSS Vulcan reticle. This reticle has a 230 MOA dotted outer ring and a 3 MOA center dot.
The purpose of this reticle is to help you find the center dot quickly if you are off center. To learn more about the ACSS Vulcan reticle check out our article here.
The dotted outer ring can be turned off by holding down the "-" button for 3 seconds.
The main advantage of the ACSS Vulcan reticle is to be able to find the center dot quickly when drawing the pistol.
All the features are the same as the 507K except for the reticle, and this is available in both red & green.

4. Holosun EPS Carry - Closed Emitter Option - Best Enclosed Emitter Option
Buy the EPS Carry At The Best Price
The EPS Carry is very similar to the 407K and 507K except it has one major difference, it is an enclosed emitter optic. This means the laser emitter is protected by a hood. So dirt, mud, or debris will never get in the way of the emitter to distort the reticle. It also has the highest waterproof rating at IPX8.
There are 3 versions of the EPS Carry. The 2MOA, 6MOA, and MRS Versions
The MRS version has a solar panel on it which acts as a solar fail safe to power the reticle of the battery dies. It also gives you an extra auto brightness feature which can be toggled on or off.

5. Holosun SCS Carry Green Dot - Best Solar Recharging Option
Buy the SCS Carry At The Best Price
The SCS Carry is similar to the EPS Carry in that it is an enclosed emitter, except it features Holosun's latest "Solar Recharging Technology".
It has an internal rechargeable battery with theoretical unlimited battery life. The battery has a 20K hour power reserve which is constantly being recharged. The optic charges the battery faster than it consumes. It has the MRS (multi reticle system) and is available in green dot only. You can use the 2 MOA dot, 2 MOA Dot + 32 MOA Circle, or 32 MOA Circle only.
This model doesn't have Shake Awake like the others, but recommend from Holosun, you just leave it on and it will stay on. It is constantly recharging from natural and artificial light sources. It does have a power off button if you wanted to turn it off.
This optic is a great option if you are looking for something super sleek, and where you never have to worry about batteries. Just turn it on and keep it on!
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.

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.
