Best Optics For Glock MOS [All Models]
Holosun HE508T – Best Overall
The Holosun HE508T is a solid Titanium made red dot optic for the Glock, which is about 30% tougher forged 7075 T6 aluminum optic
This means it’s significantly stronger than the old school Trijicon RMR.
Besides the beefy outer body construction, the optic also has the longest battery life up to 100,000 hours using a single CR2032 battery, which is 5.5X more than the Trijicon RMR.
In addition, the solar panel provides the optic with fail-safe battery source so it will always remain on.
But there is more…
The optic also feature Holosun’s Shake Awake technology, which activates the optic when it senses motion, and it turns off when remaining static. This feature saves battery juice even more and turns on based on the last setting recall.
Best for conceal carry because it’s the most durable optic, which also the width doesn’t stick out too much.
- Parallax free optical design, with unlimited eye relief.
- Multi-reticle System.
- Shake Awake technology with last setting recall.
- Solar cell and high capacity battery provide dual power supplies.
Trijicon SRO – Best Large FOV Optic
Reviewing the Trijicon SRO against the original RMR showed us significant upgrades side by side.
The two biggest difference is the increased lens window size for better dot tracking & top-loading battery access.
It kept the same mounting and overall body dimension as the RMR, so you don’t have to modify anything to fit the Trijicon SRO if you’re already an RMR user.
The SRO really made a big difference in how frequently people can acquire the dot and align the sight picture without any problem. Even if the shooter slightly draws the gun off-center, he/she can still pick up the dot and not lose it during fast followup shots.
Lastly, the top-loading battery access allows the user to switch to a fresh battery without removing the sight, which saves energy and time finding the tool and to re-zero the dot.
It’s one best looking optic that also performs very well on the Glock…Highly recommend it.
- LARGE, UNOBSTRUCTIVE FIELD OF VIEW: Parallax-free and compatible with suppressor-height iron sights
- CLEAR, CRISP DOT: Fine-tuned, illuminated reticle, coupled with exceptionally clear front lens, offers a clear sight picture with a crisp 2.5 MOA Red Dot
- EASY, ADJUSTABLE WINDAGE & ELEVATION: Tool-less design makes zeroing hassle-free
- RED DOT PISTOL READY: Designed to fit on many of the most popular red-dot-ready brands on the market (mount not included)
Leupold DeltaPoint Pro – Best Legacy Competition Handgun Optic
The DeltaPoint Pro has a slightly taller and wider lens than the Trijicon RMR, and it’s one of Leupold’s premium micro red dot optics. It’s designed for pistols, rifles, and shotguns
In addition, what we like about it is it’s first ever top-battery loading design, which doesn’t require tool for sight removal in order to switch to a fresh CR2032 battery. It’s a awesome design that has inspired other optics company to do the same.
For the longest time, the DeltaPoint Pro has been people’s favorite competition optic because it has a slightly wider lens window than the RMR. It’s durable and effective for placing the dot on targets to shoot at.
It’s mostly recommended for competition style shooting only for the reason that the it doesn’t have a quite user friendly reticle brightness adjustment system, which can be annoying for conceal carry users who just want to simply adjust the brightness relative to the lighting condition throughout their day.
- Model #119688 - DeltaPoint Pro with 2.5 MOA Dot reticle and Matte finish
- Battery saving Motion Sensor Technology - Automatically deactivates illumination after 5 minutes of inactivity yet reacts instantly when movement is detected.
- DiamondCoat Aspheric Lens increases the usable field of view by up to 56% and provides a scratch resistant crystal clear image.
- Tool-less top loading battery access and true 1 MOA click adjustments provide unparalleled ease of use.
Aimpoint ACRO P-1 – Ultimate Weather Proof Optic
The Aimpoint ACRO-1 is a unique optic that solves the problems that open emitter micro red dot couldn’t. It has the enclosed body design to deter dirt, water, mud, and other nasty stuff from getting into the optic.
Have you ever had stuff fall into the cup of those open emitter red dot when you conceal carry or on a windy/sandy competition range?
If you have had that happen before you know it basically smears the lens and potentially blocks the emitter from projecting the dot on the glass.
Check out this review by Military Arms Channel as they field test and torque this opitc:
- Enclosed housing seals all electronic components safely within the sight
- Enclosed optical channel prevents dot from being blocked by contaminants
- Can be mounted to optics-ready pistols using optional adapter plates
- Up to 1.5 years of continuous operation (at position 6) using one CR1225 battery (included)

Vortex Razor RDS
The Vortex Razor micro red dot is one of Vortex’s premium product. One of the best thing about it is that it sits quite high on the Glock MOS with the factory mounting plate, which offset the tendency people have where they aim low below their eye level.
The Razor’s overall profile is very similar to the Leupold DeltaPoint Pro as far as lens width and height
What’s different from the DeltaPoint Pro is that it’s slightly heavier (1.4 oz, where DeltaPoint is about 0.63oz), and the Vortex Razor has a bit more blue and green hue.
Overall it’s a great optic, but best for range & competition use.
- Enclosed housing seals all electronic components safely within the sight
- Enclosed optical channel prevents dot from being blocked by contaminants
- Can be mounted to optics-ready pistols using optional adapter plates
- Up to 1.5 years of continuous operation (at position 6) using one CR1225 battery (included)

What To Look For In A Red Dot For Glock MOS
Glock pistols are reliable and fun to shoot when you mount a reflex sight to it, it helps you shoot faster and aim better only if you practice a lot with it.
It’s a double edge sword where it can help you or it can totally slow you down.
Field Of View – Larger Window, Better Dot Tracking
The lens size of the micro red dot is important for picking up the dot fast, and also be able to track the dot on follow up shots.
The bigger the window, so it’s subjectively easier to shoot with a faster timer with it, and it’s the most important spec that helps shooter solve the sight picture inconsistency problem.
Dot Size Selections – 2 – 8 MOA
For close-range pistol shooting, 2 MOA to 8 MOA size dot is great because they cover a wide area of a target, which means faster sight picture acquisition and better shot placements.
This is useful for competition type of shooting when using a full-size Glock like the 34, 35 and 17L. For defensive shooting, aiming with a dot isn’t really necessary because generally, shit happens within 2-8 feet away, point and shoot will be just enough.
1 MOA is generally optimized for precision long-range shooting using a rifle for its refined dot that covers 1″ diameter at 100 yards.
Long Battery Life – 30K+ or 100K+ Hours
The industry standard for a micro red dot sight is about 2 years using just 1 CR2032 battery. It varies from optic to optic, based on adjustable brightness settings and the ones with advanced power circuits that extend the battery life even up to 10 years like the Holosun 507C, 407C, and HE508T.
Having a long battery life is always good for a pistol mounted red dot sight. It’s always annoying when the red dot optic goes dead when you’re ready to shoot or during your range session.
When you have something that lasts extremely long without a battery swap, it gives you the confidence and peace of mind every time you pick it up, you know it works.
Another great feature you should be looking for is the top-loading battery access, which eliminates the need to remove the optic for a battery change, and the need to re-zero your dot.
This is the exact reason why the NEW Trijicon SRO and Leupold DeltaPoint Pro are so much better than the original RMR when it comes to battery compartment access.
Durability – Survives Repeated Recoil & Shock
For defensive handgun shooters… There is a higher chance that you will rack the slide against the red dot one-hand on something like a table, hard edges, belt…etc
Yes, you can do that ONLY if the optic frame is strong enough!
Currently, Trijicon RMR, Holosun 507C, and HE508T can deliver that performance without breaking or lose zero, due to their rugged frame body made with 7075 T6 forged aluminum and Grade 5 Titanium (HE508T).
Glock MOS Optics Tips If You Can’t Easily Find The Dot
Before we discuss some optic equipped Glock shooting tips, let’s briefly cover what are some of the negatives of using a red dot on pistols.
The biggest issue: Sight picture & dot alignment inconsistency. Hard to find the dot OR Track the dot
Optic pistol shooters have always had love and hate relationships with slide mounted red dot sights, where it doesn’t matter how much you practice the draw you will always tend to miss the dot or have to find it, even if you’re just a hair off.
Tip 1: Use a bigger window optic for better dot acquisition and tracking
Tip 2: Experiment with a different size backstrap to alter your grip angle, which allows better and sight alignment
Tip 3: Practice, Practice, and Practice
Round-Up
The Glock MOS series pistol is a great gateway gun into shooting a pistol with an optic. It saves money and the time sending your slide to someone to get it milled.
Right out of the box, it’s ready for an optic with mounting plates for Trijicon, Leupold, and other major optic brands.
The Holosun HE508T is our favorite pick for its titanium durability and it’s basically a stronger and longer-lasting micro red dot than the Trijicon RMR. It’s great for conceal carry and range use.
Our 2nd favorite pick is the Trijicon SRO for its newest improved lens for faster dot tracking… All about the speed!
