Reviews Of The Best Night Sights For Glock 19

1/Trijicon Night Sight Sets


Are you tired of the ineffective iron sights when it gets dark? Do you still want to continue practicing your shooting even after darkness sets in? To help you overcome some of these inefficiencies, this product from Trijicon is a great option you are looking for the best around.

By utilizing the 3-Dot setup, this product provides you with an aiming solution, even in a low light condition. Its brightly colored, high visibility front sight uses a photoluminescent paint which glows in the dark. You are then able to aim at and acquire a target faster and with improved precision.

To further improve the appeal of this night sight, the rear sight features a unique subdued design. This design incorporates a serrated and angled surface to reduce glare and at the same time enhance the focus on the front sight. It does this by using rings painted black to allow you focus on the frontal sight.

With this night sight, you should not struggle to acquire a target. With a U shaped notch on the rear sight, there is no blockage to the front sight view at all times. Another feature I find great about these night sights is the use of a Tritium Phosphor lamp.

This lamp consists of a glass filled with tritium to create the kind of superior illumination you need in a low or no light environment. Moreover, if you own any Glock 17 to 39 models, then you can comfortably use this night sight.


  • Fits some Glock Models

  • Has bright and durable tritium lamps

If you have decided to go the Glock way, why not go Glock all the way up to the Sights too? In fact, most people do not look beyond these night sights when shopping around for one. It is for a good reason though, as these are one of the best night sights for Glock 19. They are high quality and are compatible with most of the Glock Models.

The Glock OEM night sights have a simple, 3-Dot setup that is compatible with almost all the Glock pistols. For compatibility, the height and style of the traditional Glock sights stay the same retained so that they are easy to install in an instant.

The tritium contrast points provide clarity of targets, whether in the day or at night. The inserts glow green during the night, and when illuminated during the day, they glow white. The 6.5 mm high Rear Height works in hand with the front sight to easily acquire a target and quickly take aim. Such a capability comes in handy when in self-defense situations in no light conditions.

As a testament to the popularity of these Night Sights, most of the police and military forces around use these sights on their Glock Pistols. This trust in these sights by professionals is for a good reason that you may also love. They are reliable, effective, and are complementary to your shooting skills.

Because of a screw in type front sight, you can firmly fix it in place without the risk of it falling off when in use. Coupled with their compatibility with Glock Pistols, you do not have to learn how to use another sighting method within your range of firearms.

3/Ameriglo Pro-I-DOT for Glock


The Ameriglo night sight is among the most popular sights for an array of Glock pistols. It comes with the features that make it a common night and day sight for Glock 19 among others. Among some of the features to look forward to is the green front and rear lamps which glow brightly in the day or at night.

These tritium lamps are inserted inside an aluminum housing, which is then housed in the actual steel sights. With this layer of protection, the durability of the sights is immensely improved. Moreover, the steel sights are then coated with black oxide to protect it from corrosion in case it gets into contact with moisture.

In addition to the oxide finish, a sapphire screen is used to protect the delicate tritium inserts from residue. Fitted with an orange tritium dot on the front sight, aiming during the day is no problem.

With all these features, you might think these sights are complex to use. However, the reverse is true. They are easy to use and fit great onto a Glock 19, with a simple dovetail installation.

Perhaps what could be troubling for some is the used of the IDOT set up, more so if you have been used to the common 3-Dot setup. With time, I had got used to this setup and found it faster and easier to use.

Various law-enforcement agencies around the globe use it in their day to day activities. The main reasons for its high regards are its impressive brightness and versatility.

Besides these two, the Meprolight has other desirable features for your convenience. For instance, this product comes in a variety of lamp color combinations. Of all these, I find the green/green lamp combination to be more convenient than any other.

The other option, a green/orange combo tends to disappoint during the night. Alternatively, you could also choose a yellow rear/green front color combination. By choosing the Meprolight, you will enjoy the benefit of a 3-Dot tritium optical system. With this setup, you get a longer shooting range and an improved accuracy, particularly if you are a tactical shooter.

Of the three dots, two are on the rear sight while the remaining dot is on the front sight. The contrast between the two sets of lamps is what makes target acquisition easier and much faster than in the case of little contrast.

For those who love a 3-Dot setup with the standard dovetail fit rear and front sight, then these Ameriglo Night sights are some of the best options you can choose from. Made of tritium inserts, the three dots are outlined with a white color which is responsible for reflecting light.

Apart from the white insert outline, the inserts themselves are made green to provide the high contrast needed in the dark. These sights perform exceptionally well as you would love to, without adding too much extra height to your Glock 19. The rear sight adds about 0.310 inches, while the front one adds about 0.314 inches in height to the Pistol.

The other great thing about these sights is that you can use them during both the day and night. The three dots glow impressively in the day, although they are meant for use at night. A combination of green inserts surrounded by a white ring provides you with the ability to quickly aim at a target at a considerable distance and then accurately hit it.

Another admirable feature of this product is its ease of installation. It has the standard dovetail fit where you simply slide the sights in, and you are done. Such a design is great if you need to transfer the sights from a Glock to another one.

The best night sights for Glock 19 should be able to provide you with an instantly visible sight, whether in a no light or a low light situation. The Trijicon Suppressor, for instance, is fitted with tritium phosphor LED glass lamps for a battery-free glow. Such a feature is essential when you need to find a picture in all lighting conditions.

It is one of those products that you should not hesitate to buy. An enhanced protective design is put in place to protect the tritium inserts from cleaning solvents that may be harsh and the heavy recoil from the pistol.

The gas lamps are housed in aluminum cylinders for protection against external elements. A rubber cushioning of silicone is then added to absorb the shock from the heavy recoil.

The protection does not stop there. An additional sapphire glass window is used to cap each of the tritium lamps. Besides keeping out residues, piercing forces, and solvents, this sapphire window also evenly distributes the light produced.

With an everyday use in mind during the design, the height is increased so that it can be used alongside a suppressor. Alternatively, you can also use it as a backup iron sight in a slide mount and red dot sight design. An example of this setup is the Trijicon RMR.

When using these sights, the chances of missing a target are quite slim. The 3-Dot setup increases the shooting accuracy at night by considerable percentages. Moreover, the shooting is instinctive as the sights enable you to aim much faster than conventional sights.


  • Resistant to harsh solvents

  • Recoil absorbing silicone rubber

  • Faster target acquisition

  • Rugged, durable construction

  • Fits great

  • Works well with suppressors

  • Height appropriate for a vortex-red dot


  • At times not very bright in the dark

7/TRUGLO TFO Sights for Glock Pistols


The previous sights in this list have been using tritium for illumination. However, as I had mentioned earlier, fiber optics too do form a great technology for providing the sighting you need. Fiber optics are famed for their rich and high visibility glow in any light condition, either the dark or at full light.

What if you get a blend of the reliable tritium inserts and the glow rich fiber optic? These sights use exactly this blend, to give you the best of both worlds. They use the revolutionary tritium-illuminated fiber optics, housed in CNC-machined steel. With these, you can comfortably transition from low light to darkness with the confidence of retaining your sight picture.

Made with a snag-resistant sights design, this product is meant to fit in all standard holsters. With them, you get a professional grade night sights for your Glock 19. The setup consists of green tritium fiber optics for clear visibility during the day or at night. During daytime, the green inserts are seen as dots, while they glow at night.

The inserts are availed in either yellow or green, for the rear sight. Having yellow inserts increases the contrast with the front sight so that you have a more brilliant sight picture in the dark. You will then have the ability to focus on the green in front quickly. The steel housing is then given a fortress finish as a protective coating.

When using these sights, you will realize that they are very sensitive. This sensitivity means that installing them requires extra skills when mounting. If you have some doubts, then you could visit a gunsmith to have it done for you. Another issue is the inefficiency of the inserts when in the presence of a stronger light source such as flashlights or headlights.


  • Brilliant sight picture

  • Snug-free design

  • Easy to use

  • Withstands harsh elements

  • Available in a variety of rear inserts colors

8/XS Sight Systems for Glock 19


Although it is not the fancy fiber optics-tritium illumination technology, these sights’ simplicity and ease of use is what makes them one of the best around. Take for instance, the I-Dot style of acquiring a target. It is a simple to use, yet an effective way of aiming. Regardless of the lighting conditions, these sights still get the job done.

The setup consists of a front large tritium dot, while the rear sight houses the tritium I-line. By making the front sight bigger, the speed of sight acquisition is greatly improved. What’s more, there is also a white ring around the front tritium insert for reflecting light when it gets dark. Visibility is retained in low light conditions with this design.

There is a certain tendency of night sights producing a blurred or an obstructed view when you are on the move. However, these glock sights feature a unique express rear which works to prevent any obstruction of the front sight when you are aiming at a target when moving.

A steel construction, which is given a black anti-corrosive finish, is responsible for protecting the inserts from elements. It could be solvents you use to clean the pistol, or just moisture it picks up in the course of its use.

The sights are made to be slightly thicker than the standard factory sights. It is a way of making the sights easier to install and fit in most if not all of the Glock Holsters currently on the market.

How Do You Choose The Best Night Sights For Glock 19?

Out here, a product labeled as “best” may not necessarily be the best regarding performance. You, therefore, need to take extreme care when making a choice of a night sight for your Glock 19. The purpose for which you need them and the type of sights plays a big role in the choice you make.

If you are still not sure, then this buying guide will highlight for you the things you need to consider before buying the best night sights for Glock 19.

1/The Type Of Night Sights

The main aim of buying a night sight is to achieve a certain purpose. To perform these purposes and meet users’ varying styles, they are made of various types to provide you with a huge variety to choose from.

With these, your style preference will play a critical role in determining the one you go for. Ensure it is one that you are most comfortable with. Here are the types from which you will have to choose.

  • I-Dot Night Sight

Just as the name suggests, these types have a single painted, I line, on its rear sight. This is just under the notch. The setup also includes a single dot positioned on its front sight. When taking aims, you align the dot and the I.

  • The 2-Dot Night Sights

This setup consists of two dots, positioned on the rear and front sights. Different dot sizes are used with the dot on the front sight being larger and brightly colored. The rear sight has a smaller dot under the gun notch.

The larger and brighter front dot allows you to acquire a target even in poorly lit conditions quickly.

  • The 3-Dot Night Sights

This setup is common in most Glock 19-night sight setups. This design is such that two dots are at the rear, while the other one is in front. Instead of having bright paint, the best night sights for Glock 19 have either a fiber optic or tritium inserts.

Such a set up improves visibility and target acquisition in the dark.

  • Sight Ledges

If you usually take part in one-handed training operations, then this sight could be a great one for you. This is especially for a semi-automatic handgun. It is for this reason that it is less common. The setup comprises of an elevated rear sight and triangular front sight.

  • Rear U-Shaped Sights

It is a less common type, just like the sight ledge. The people who mostly use it are those who participate in shooting competitions. The sight provides them with the ability to acquire targets from a long distance out.

2/Usage Capabilities

Before buying any product, the first thing to do is ask yourself what you will be using it for. It is only after answering this question that you can choose one that particularly meets its intended use.

Consider how some of the night sights for Glock 19s differ regarding their applications. Some of them are suited for night use only but become lousy during the daytime. Others will work best in both conditions.

  • Night Purposes Only

These sights are meant for strictly nigh uses. If you decide this is the types you want, to counter for the effects of poor eyesight at night and low light conditions, then there are several models to choose from. It could be a 2, 3 or I-Dot type.

From these existing models, find one that best suits your needs. Additionally, look for an optic technology that allows for better precision and target aim. There are three types to choose from which are tritium, fiber optic or a photo-luminescent paint.

The night only sights are mostly meant for Glock 19s that you will be using mostly at home for your self-defense.

  • Multi-Purpose Use

If you indeed want to enjoy the best of both worlds, then these are the types to choose. For the added advantage, you will have to fork out more money to afford the added aiming abilities.

3/Frequency of Usage

Before you spend a fortune on the best night sights for Glock 19, you need to know how many times you will be using it. There is no point in spending too much money on a sight that will be just lying around in the house.

Nonetheless, it also makes no sense to buy a poor quality one that you will frequently use. Take an example of a home defense gun. For this Glock 19, I think you do not necessarily need a top of the range model as it will be just lying around in a drawer most of the time.

And unless you live in a mansion, I don’t see the point in buying a sight that aims accurately for more than 50 yards out. Most of the cases you will be dealing with are at close range and rare.

The same is not true for the one you will be using for range practice. If you need a night sight to help you overcome your limits, then only the best will work for you. You need to prioritize accuracy of aim, longer distances, and durability over repeated usage.

Reserve the best night sights for the Glock 19 you carry around on a daily basis. Either way, the optic technology used should be able to be bright at night, glow reasonably in low light, and remain visible in bright light.

4/Shooting Range

Every night sight has its aiming capability. You, therefore, have to work out a rough estimate of the distance you need to be accurate at, then make a choice based on that. For short shooting ranges, like the home defense pistols, the I-Dot setup seems like a good option.

Then there are those with medium aiming accuracies. Those with sizeable homes and want to accomplish other shooting tasks can opt for these sights. In this list are some of the I-Dot sights, as well as 3-Dots with notches on the rear sight in the shape of a square.

The best night sights for Glock 19 are those with a long-distance aim. If you are a shooter with above average shooting skills, then a shooting range of over 50 yards sounds like a good deal. The 2 and 3-Dot setups fall into this category.

5/Your Budget

Frankly, night sights are not that very expensive when you consider their durability. It is not like you will have to buy one after every half a year or so. Nonetheless, they are still priced differently to suit your budget.

You will get low-cost sights with which you will have to take care so that you don’t end up with a cheap and lousy sight. I suggest you check what reviewers say about it, and its ease of installation onto a Glock 19. At low costs, expect these to have quite limited capabilities.

Then there is the medium to high priced sights. If your budget can accommodate these, then the better off you are. They perform exceptionally well, especially the high-end ones.


The best night sights for Glock 19 make an essential addition to your pistol. They greatly improve the visibility of targets during the night when you are not able to see properly. You are then able to defend yourself as every shot would count and find its intended target.

In this review, the best night sights are the Trijicon Night Sight Sets for Glock Pistols. They boast of better visibility than its counterparts in any lighting condition and a subdued design in the rear sight. The rear sight surface is serrated and angled to minimize glare.

Sight acquisition is enhanced by the inclusion of a U notch on the rear sight, which works in combination with the tritium phosphor lamps. Illumination remains superb under any lighting condition in the process.
