Optics
Excellent optics allow you to see your target clearly, no matter if you’re aiming under the bright sun or in low light. You want a sight that brings your target into sharp relief, with colors that pop and details that stand out, making it easier to hit your mark every time.
How do we rate it?
We rate this factor based on clarity, range of visibility, and how well they maintain accuracy across various lighting conditions.
Build Quality
Get a sight with sturdy construction so that it can handle daily use and abuse, especially if you shoot regularly. Durability and resistance to wear, shock, and water are key components of build quality. High-quality materials and construction ensure the sight can withstand rough handling and adverse conditions.
How do we rate it?
We score build quality based on materials used, design robustness, waterproof and shockproof ratings, and overall longevity.
Ergonomics
A good sight should feel like an extension of your Glock. How the sight fits with the firearm and its usability, including ease of installation, adjustments, and operation.
You don’t want your sight to add more weight than the acceptable amount, especially for concealed carry. You’d also want it not to be sharp around edges to avoid snagging your clothes every time you draw your gun. A bulky sight will also be difficult to conceal.
How do we rate it?
We rate this factor based on installation simplicity, ease of use, adjustability, and how well the sight integrates with the Glock’s design.
Battery
Illuminated Glock sights can consume a lot of battery unless they’re radioactive like tritium. And even with tritium your sights will dim with time. So, you want to have a site that has a battery life of at least 10,000 hours. This will hold battery changes until after a year or two for battery-operated units like a red dot. It’s better if you can get an optic with 50,000 hours of battery life, but you’d need to spend a bit more for that.
If you find changing batteries and charging your optic bothersome, you can also go for tritium-powered sights like some of our picks below, but there is a downside! For tritium or other technologies, expect to need to replace your sights for maximum brightness after 5+ years!
How do we rate it?
We give higher scores to sights that have longer battery life under normal use conditions. We also evaluate availability and cost of replacements.
Illumination
Consider the front and rear dot’s size and brightness settings. Some sights are designed so that the front dot is brighter and bigger to make it easier to focus out and on your target. This setup also promotes fast target acquisition.

It’s better if you can get an optic with 50,000 hours of battery life, but you’d need to spend a bit more for that.
Most of our picks below are night vision compatible. Their dots are also the brightest and long-lasting in the market. So even if you spend a little more, it will be worth it.
How do we rate it?
We evaluate the brightness levels, daylight visibility, and reticle clarity. A score of 5 means excellent visibility in both bright sunlight and low light conditions, and a reticle that remains sharp and defined.

Score: 4.43/5
The Trijicon HD XR night sights may be compact but they have the precision of an iron sight. They feature a thin front post that’s outlined with a glow-in-the-dark, photoluminescent paint and a “U” notch rear that’s outlined with black. This combo promotes efficient front target acquisition. We are impressed with how this sight’s advanced technology allows you to quickly identify and engage distances even from long distances.
However, all its features and performance come at a steep price.
Pros

- Great for low-light conditions
- Easy to install

Cons

These Truglo night sights generate light from premium-quality Swiss tritium that delivers unparalleled brightness and clear sight picture in every lighting condition.
Its dots glow bright white during daytime and glows green when in the dark. What’s great is this night sight doesn’t require any power source, so no need to charge it or buy batteries!
Pros
- Affordable
- Really bright
- Durable construction
- No batteries or charging needed
Cons
- A little difficult to install
What Customers Say
These were a nice upgrade for a Glock 26. The tritium is nice and bright and both front and rear sights fit perfectly. Sometimes rear sights have to be sanded a little to get them in. I didn’t have to alter this one at all. Went in half way by hand, then used a sight pusher to finish. I also like that this one has a set screw to lock it in place. rbtharris

The Trijicon Rugged Miniature Reflex Sight is engineered in a unique housing so any kind of impact is diverted away from the lens.
This reflex sight is compatible with handguns and rifles. It’s also proven to survive accidental drops and take an impact from a doorway or whatever else you may hit it on.
It’s also equipped with automatic brightness adjustment or you can choose to adjust it manually. Plus, the Trijicon RMR has a battery-saving feature and a button lock-out mode, making it perfect for concealed carry.
However, it would have been better if the sight didn’t have to be dismounted when changing the battery.
Pros
- Audible windage/elevation adjustment clicks
- Comes with warranty
- Easy to install
- Waterproof and shockproof
Cons
- Very expensive
- Requires dismounting when changing batteries
What Customers Say
“This easily mounted on my M&P C.O.R.E. 9mm, and co-witnesses with the iron sights. It was almost on target right out of the box, requiring only a minor adjustment. I use it mostly for steel-plate and bowling-pin competition shooting, and I can get on-target very quickly.”

XS Sights’ version of tritium night sights are designed so that the front sight is bigger and glows brighter than the rear sight to prevent confusion in low to no-light situations.
The R3D’s convex dot is easy to clean and is resistant to gunpowder residue. While its body is chemically resistant to acetone-based and ultrasonic cleaners. And since it’s tritium-powered, no other power source is needed!
Pros

- No charging or batteries required
Cons
- Not completely snag-free
What Customers Say
