You see the almighty Glock pistol everywhere, in all its simplistic splendor.

Glocks are the most popular semi-automatic pistols in the world, and concealed carry users are still having a hard time choosing between the Glock 26 and the Glock 43. Some can’t even decide which is the best Glock!

It’s definitely one of the best CCW choices, so there’s no wonder there are countless aftermarket upgrades and holsters for it. Whether it’s a Glock 19, 26, 43, 43X, it’s practically the gateway to gun modders’ heaven.

What you get with your Glock purchase is reliability, and every part works as intended. But, the Glock factory OEM (original equipment manufacturer) sights aren’t very visible nor durable in comparison to the aftermarket sights you can find today.

Many folks just don’t like the barely visible white, U-shaped rear sights with a front white-dot sight. That’s why today we’ll talk about Glock sights, and I decided to round up the best Glock sights you can find on the market.

I tried to make it as diverse as possible, for every purpose and with various price tags, so you can find the most suitable one for your purpose.

Of all the aftermarket parts you can purchase for your Glocks, the sights should be the first on your grocery list.

Top 5 Glock Sights

Our Top Pick – AmeriGlo Green Tritium 3-Dot Night Sights

AmeriGlo Classic Style Green Tritium
  • Pressurized tritium lens
  • Good for both day and night time
  • Great value
  • Well-made steel construction with a rubber cushion
  • Lightweight
  • Red dots not available

The AmeriGlo Classic sights are undoubtedly one of the most valuable 3-dot Tritium sights for most Glock pistol enthusiasts. For a fair price, they offer excellent illumination for the front and rear sight during the day and low-light situations or the nighttime.

They’re 3.6 inches wide, 5.6 inches long, and 1 inch high, and available for most Gen 5 Glocks like the Glock 19, Glock G43, and the Glock G48.

The AmeriGlo is perfect if you want to keep the standard Glock look, and the steel construction is carefully crafted to suit tritium lights. It’s easy to mount and install with the rear sight screw.

The sight’s green tritium center is a sapphire lens, pressurized and wrapped in aluminum, and there’s a silicon rubber part that keeps it put. It has a white outline around the tubes for easier target acquisition.

Though these sights are only available in green dot, I chose the AmeriGlo Classic 3-dot simply because it caters to most Glock users. What they offer is excellent daytime or nighttime brightness, and they’re easy to mount for moderately-priced Glock sights.

Runner-Up – Truglo TFO Tritium and Fiber-Optic Handgun Sights

TRUGLO TFO Tritium and Fiber-Optic Handgun Sights for Glock Pistols
  • Excellent brightness
  • Half an inch tritium sights combined with fiber optics
  • Large, but surprisingly snag-free
  • Durable steel construction
  • Easy setup
  • Longer front sight might not be suitable for some Glock models
  • Might be heavy for some

Here’s a standard in Glock sights. The Truglo TFO Handgun Sights come close to the Ameriglo, but they’re a solid option if you’re switching sights.

What makes the Truglo special is its 3-dot TFO (Tritium Fiber Optics) light source technology that glows brightly and its ability to adapt to many light conditions and contrasts.

The brightly-lit green fiber light source is perfect for the day, while the tritium works at night. They’re very distinct and offer great target acquisition.

They’re perfect for both Glock veterans and pistol newbies, and installing takes no special effort. Simply center the rear on the slide with a bedded vice or pusher tool, and tighten it with a couple of swipes.

The Truglo TFO 3-dot sights have a CNC-machined steel construction for durability. Though they’re slightly bigger than standard Glock sights, they’re snag-free and suitable for most holsters.

The 1.3-ounce weight might make a difference in your pistol handling, but they’re moderately heavy in comparison to other high-end sights.

Regarded as a high-end brand, Truglo manufactures pistol sights with very distinct and visible brightness that are guaranteed to suit any Glock fan.

Best Budget Option – Meprolight Glock Tru-Dot Night Sight

Meprolight Glock Tru-Dot Night Sight
  • Night sights perfect for low light settings
  • Durable steel construction
  • Reasonably priced
  • Comes in green, orange, or yellow sights
  • 12-year warranty
  • Tritium tubes work well during daylight but more suitable at night

The Meprolight is one of the most effective, self-illuminating night sights you can buy for your Glock at a very attractive price.

Meprolight’s Tru-Dot is durable enough for law enforcement and security agencies, so that’s some guarantee of their longevity.

Meprolight claims their dots are 20% brighter than your standard sights, but they offer the best visibility during the night. After what I’ve seen, it’s pretty close to the truth there.

The Meprolight Tru-Dot Night Sight is designed to be effective for low or no-light conditions. It might be one of the essential sights for EDC, which most often needs to be suitable and proficient at night.

The Meprolight is available in multiple colors because the manufacturer knows some folks have a problem with green dots.

What separates the Meprolight from the other sights is the price and nighttime effectiveness.

Best Premium Option – XS DXT2 Big Dot Night Sights

XS SIGHTS DXT2 Big Dot Night Sight for Glock Pistols, Front and Rear Glow in The Dark Tritium Handgun Sights
  • CNC-machined steel
  • Unique front and rear alignment
  • Excellent brightness
  • Available for all kinds of Glocks
  • 10-Year warranty
  • Expensive
  • Takes a while to get used to

The XS DXT2 Big Dot night sights are a unique set of sights that vastly differ from all the other brands.

A high-contrast, photoluminescent front sight with a large red ring and a V-notch rear sight, called dot-the-I sight, prevents you from confusing the front and rear. The patent-pending glow front sights absorb daylight and glow in the night.

The XS DXT2 has a unique targeting and sighting technique. You don’t have to align the front and rear sight—just place the large dot on top of the vertical bar in the center (also called  “dotting the I”). 

It might take some time to get used to this aiming system, but it’s ideal around the 10-15 yard range once you get the hang of it.

As the name suggests, XS DXT2 Big Dot has a big dot for the ultimate visibility and target acquisition. Not only that, but you get the XS 10-year warranty, granted anything happens to this already durable piece of sights. It’s one of the best options if you have a big budget.

Five different sizes are available, and all of them come in two colors: yellow and green.

You can also check out their XS RAM Night Sight with a standard tritium 3-dot system if you’re looking for something more simple and similarly priced.

Only this time, the XS RAM Ember Glow-Dot technology enables you to see the front sight better than the rear, which might be very useful for some Glock enthusiasts.

Trijicon HD XR Tritium

Trijicon HD XR Night Sights
  • Compact and lightweight
  • Sapphire jewel cap with excellent illumination
  • Metal construction for durability
  • Narrow front sight and U-notch rear sight for a better field of view
  • Expensive
  • Needs a gunsmith for installation
  • Sharp edges
  • Not snag-free

Undoubtedly a high-tier model from Trijicon, the Trijicon HD XR sights are built for fast target acquisition both during the day and night.

These sights have a big bright front dot, silicone rubber cushioning, and aluminum cylinders for protection. The rear dots have durable sapphire jewels for even light distribution. They come either in yellow or orange front sight dots.

The tritium lamps are with a 3-dot dot configuration, and the sight settings automatically change from daylight to low-light, while the front sights are the only ones that are colored.

This unusual setting might take a while for the regular pistol shooter to get used to, but they offer a very bright and consistent glow. Trijicon HD XR sights are durable, offer excellent target acquisition, and can be found for all kinds of Glocks.

However, they’re pricey, uncomfortable for some holsters, and require a gunsmith if you don’t want any issues with stability. That’s why I placed this premium option a bit lower than the others.

Though the Trijicon HD XR sights are available for most Glock models, I recommend them for the Glock 19 users, especially if you’re going for a tactical feel. They can last for years.

Honorable Mentions

Best Suppressor Lights – Trijicon Suppressor Tritium Night Sights

Trijicon Suppressor Night Sights
  • One of the best suppressor Glock sights with an increased height
  • Easily visible with co-witness and won’t interfere with optics
  • Durable steel and aluminum construction
  • Silicone rubber cushioning
  • Sapphire glass window with phosphor LED lamps
  • Easy to use
  • Expensive
  • Not compatible with some popular Glock holsters

If you’re shooting Glocks with suppressors, the Trijicon Suppressor Night Sights is a solid choice. Giving you unobstructed vision, it’s mounted high so you can have a clear shot without the suppressor blocking your sight.

The steel construction with a black oxide finish might be one of the most durable casings for sights, and the tritium lamps are protected by aluminum.

What makes the Trijicon Suppressor night sights shine is how easy they keep your focus on the dot. You can easily attain your targets with the aligned iron sights. There are no fancy accessories that come with it, just good, non-distraction sights that’ll serve you for decades.

The Trijicon Suppressor fits all kinds of Glocks from the model G17 and all the way up to the Glock 39 model with suitable, snag-free dimensions.

The elevated suppressor-height iron sights are just as bright as standard tritium sights, and they come with a white outline on the front sight, contrasted by the black rear sights for better target acquisition. It has decent co-witness in combination with the optics of your choice.

Ameriglo Pro IDOT

Ameriglo Pro-IDOT
  • High-quality Swiss tritium
  • Bright orange color
  • Very stable and durable construction
  • Perfect for Glock G30 or G36
  • Good for both self-defense and target practice
  • Perfect for low to no-light conditions
  • Difficult to install

Last but not least, we have another model by AmeriGlo, and this Glock sight has a very unique I-dot feature that works by centering the I on the dot. You’ll need to practice this aim, but once you do, you won’t be able to use any other sights.

The two green tritium lamps offer solid luminescence, and you can leave it in direct sunlight for several hours and use it for several more. Don’t worry about holstering. Even if you move it away from direct sunlight, there’s still a way to line the sights up so it can gather light.

There’s a yellow circle on the front sight that gives you a decent, not too bright contrast and helps you line up the dot system instead of a more hands-on approach from 3-dot sights.

It has a full steel alloy construction for a sturdy and durable build, and the design is square-shaped. The edges are sharp but still offer a snag-free design.

I recommend the AmeriGlo Pro I-Dot for all of you who have experience with installing sights because they’ll need a bit of struggling with tools to install them. Make sure you understand each of the handgun parts prior to installing.

While they’re more affordable than Trijicons, though not as convenient, the AmeriGlo I-Dot sights are a highly durable powerhouse with a unique aiming system.

Buyer’s Guide for the Best Glock Sights

With its hard polymer plastic construction and resilience that matches other concealed carry pistols, it’s only fair that your Glock pistol should be complemented with suitable sights.

While most of these night sights work as intended, standard sights aren’t effective in the night as much as they are during the day. For that reason, there are lots of high-quality red dot sights you can choose from.

To have an idea of how to choose the best Glock sights suitable for your model, here are some of the most important factors to keep in mind.

Material & Durability

There are many great polymer sights for your Glock, but they can be scratched or damaged after a while. That’s why I’d suggest you stick to metal sights with steel or aluminum construction and a silicone rubber cushion.

Stainless steel sights are more durable, but aluminum sights are the more lightweight option. Both do a great job in preserving your sights for a long time, but the choice is still up to you.

As for the dimensions, pick one that is suitable for your Glock model. They’re usually with a width of 1.2 inches.


What’s great about standard sights is that they are reliant on the tritium gas within the tubing, and they don’t need batteries as a power source.

Tritium is a radioactive hydrogen isotope that creates this radioluminescence. This, along with the combined innovative power of fiber optic tubes, allows pistol users a more visible sight acquisition during broad daylight.

Types of Sights

The most popular luminescent color is green, though some models can be red, white, orange, or other colors that some users prefer.

I recommend you stick to the reliable tritium sights for any kind of light condition you may find yourself in. It can last around ten years.

When talking about frames and sight styles, there are several sight profiles like the:

  • Three-Dot Sight – The three-dot sights are the most popular style; two dots on the rear and one on the front. 3-dot sights usually work well with fiber optic sights in combination with tritium inserts. Although the intense brightness might not suit some pistol enthusiasts, they’re usually a great choice for competition shooters.
  • Two-Dot Sight – 2-dot sights have a smaller dot at the rear and a large, more visible dot at the front area. The rear sight just gives the main dot a bit more focus.
  • I-Dot Sight – As seen on the AmeriGlo I-Dot, these sights are characterized by a large front sight dot and a line under the notch, so that when you’re aiming, it’s easy to just ain the ‘I’ on the dot, which easily centers your aim. It’s a unique sight that requires a bit of practice, but once you get the hang of it, it’s highly effective for all kinds of purposes.
  • U-Shaped Rear Sight – These sights are very popular with target competition shooters, which gives them an edge in long-distance shooting. The design is practically built for the 20-yard range.

All of these sights work great for self-defense and competition shooting. It just boils down to your preference. So, it’s always a good idea to try them out first before you decide.

Fiber Optics

Last but not least. There’s the consideration of fiber optic sights.

These types of sights are very visible in broad daylight and won’t wash out in the brightness, so it’s perfect for most shooters with vision impairment.

They’re usually designed with a bright red or orange sight that’s easy to spot and align, and they can work well in both day and nighttime.

When shooting a moving target under various light conditions, you’ll need a fiber optic sight that gives you a suitable brightness.

Tritium is good, but if you’re a daylight user, I recommend you stick to fiber optic sights.


Are Factory Glock Sights Good Enough?

The factory Glock sights that come with your order are decent, but there’s nothing like a bright and clearly visible front and rear sight to improve your aim. Especially since your eyes easily detect and adapt to more illuminated sights.

This is very important during a self-defense scenario where you’ll be forced to acquire your target as fast as possible, especially if it’s a low-light setting.

Is the Color of the Glock Sights Important?

Yes. Some people think that bright green dots offer better target acquisition, while others like red dot sights better. It’s up to you to test which one is more attractive and visible for your eye.

The color is important, but the brightness of the front sight should be an imperative factor.

Some people even use contrasting front and rear sights like the Trijicon HD for enhanced differentiation.


In introspect, Glock sights have truly gone a long way from standard brightness sights to the high-quality tritium technology they’re using for enhanced convenience and accuracy.

Manufacturers like Trijicon, AmeriGlo, XS, Meprolight, Truglo, and others have improved the blueprint for special rear and front sights for day or night, ensuring a clear and precise shot.

Of all the Glock sights you can find on the market, the AmeriGlo Tritium Night Sights and the Truglo TFO Tritium/Fiber-Optic Sights are some of the most valuable and cost-effective Glock sights that offer the essentials in accuracy for a fair price.

The Trijicon Suppressor Tritium Night Sights might be a better option if you have a Glock with extra addons like silencers.

Additionally, the weight and construction must not interfere with your shooting style or holster style. Try to find tritium sights that feel lightweight, especially when concealed carry purposes are in question.

With this simple buyer’s criteria in mind, you’ll make things easier to pick out decent front and rear sights for your shooting style. Just keep an eye out for a stainless steel or polymer construction, a suitable size and height, and a snag-free design.

Stay safe, shoot straight.
