Trijicon Night Sight Sets for Glock Pistols

Most of the rifle scopes and sights being used by the military today are manufactured by Trijicon. Indeed the company has acquired a reputation for making high-quality military grade optics.

It, therefore, should not be surprising that I picked the Trijicon Night sight sets to top my list. This set of sights are built from an aluminum polymer, meaning they are quite durable. Apart from being durable, these sights are easy to use in all light conditions.

There are three tritium sets two at the rear and one at the front. The one on the front features an orange ring that makes it easy to spot at night. The rear ones two tritium lamps that are visible at night or in low light.

Compatible with virtually all Glock pistol models, these sights are very easy to install. Also, the rear lights are subdued so as to minimize glare during the day. In essence, these sights are designed to work well in different light conditions.

The only downside is that they are quite expensive scope like the best scope for scar 17 compared to other options. However, Trijicon products tend to be pricier. So, this is not really a downside as it is almost common sense to anyone who has ever bought Trijicon sights or scopes.

TRUGLO TFX Pro Tritium and Fiber Optic Xtreme Handgun Sights for Glock

  • Concealed fiber optic

One of the toughest and durable sights is the TFX pro tritium and fiber optic extreme handgun sights. The outer shell of this optic is coated in a rust-resistant finish. The sight itself is built from CNC machined steel.

A unique feature of this sight is the fact that it uses both tritium and fiber optic. On the front sight is a tritium and fiber optic green dot. On the rear, you get an option of either a green or yellow dots.

The fiber optic is concealed by grooves and is almost unnoticeable. For fast and accurate sights, the front sight has a Focus-lock. The green or yellow dots are dim during the day to reduce glare and bright at night.

As with any other product, it is not without minimal flaws. One of the flaws I noticed is that the front sight is too long. For compact weapons such as the Glock 43, I found the front sight to be a bit too long.

This is something that other users have also commented online. Nonetheless, the front sight does a good job of helping you acquire the targets in different light conditions. This is the main reason why it gets to occupy position two on my list of the best tritium sights.

  • CNC machined steel construction
  • No batteries required
  • Concealed fiber
TRUGLO TFO Handgun Sight Set - Glock 42/43

Closely related to the Truglo TFX, the TFO handgun set sight offers almost the same features. However, it a bit shorter compared to its counterpart. It sports the same CNC machined steel construction as its sibling.

What I particularly loved about this model is that it fits in almost all types of holsters. This is thanks to its design. There are three sights, one at the front and two at the rear, all of which have a green tritium highlight.

This green highlight lights up at night and appears as a bright dot during the day. In this regard, it is designed to work in different light conditions. And similar to the TFX model the fiber optic is concealed making it hard to spot.

In regards to installation, the process of installing the sights can take about ten minutes. Thus it is relatively simple to install these sights onto your Glock 43. It is also compatible with the Glock 42 and other Glock models.

Almost identical in size to the Glock 43’s stocks sights, the AmeriGlo Classic sights are the perfect fit. These sights are manufactured from high-grade CNC machined steel. So you can bet they are tough.

A green and white color scheme is used to give the sights glow in the dark capabilities while remaining visible during the day. The green tritium is surrounded by a white ring that makes it easy to see at daytime.

Since they are almost the same size as the default sights, they are a tight fit. And it will take some skilled hands to install them. Nonetheless, their compact size means they can fit in any holster without any problems.

In my opinion, they are very much similar to the pricier Trijicons in terms of quality. However, some people have complained that the tritium lamps are a bit dull. This depends on an individual though as I did not experience the same problem.

The sights are ideal for target practice as well as combat situations. In fact, they are a favorite of many law enforcement agencies. As they can match the performance of the pricier Trijicon Glock 43 night sights. For that good reason we can this sight is one of the best glock sights for combat.

TRUGLO sights are designed to be almost indestructible. And the Tritium Glo-in-the-dark night sights are no exemption. These sights are fashioned out of CNC machined steel. On top of that, there is a fortress finish for added protection.

Similar to all other tritium sights these do not require abattery. The Glo-in-the dark feature is achieved by use of a green tritium paint surrounded by a white ring. The white ring acts as the targeting dot during the day.

At night or in low light conditions the green tritium paint lights up providing a brighter view. This color scheme offers a super bright aiming dots at night. Some people claim that they are brighter than other pricier models.
The fact that TRUGLO throws in a 12-year limited warranty is a bonus.

Nevertheless, these sights are not without some minor drawbacks. One of the most common complaints from users is that the front sight tends to wear out within a short period of time.

Despite the minor drawback, these TRUGLO sights are very high quality. Without a doubt, they are some of the best sights for Glock 43. There are also smaller versions available for the Glock 17 and 16.

TRUGLO Fiber-Optic Front and Rear Handgun Sights for Glock Pistols

Tritium and Glock 43 fiber optic sights perform the same functions and it is hard to say which technology is better. Thus, while the TRUGLO fiber-optic front and the rear sight is bottom on my list it is in the same level as the other listed above.

The construction of this fiber optic night sight matches that of other pricier Truglo sights. In that, it features the same CNC machined steel construction. In regards to the sight, there are three of them similar to all other Glock 43 night sights.

At the front is a single sight with a bright red color. Unlike tritium that glows in the dark, this fiber optic sight remains highly visible in all light conditions. The bright red dot is visible during the day as well as at night.

On the rear are two sights with green dots. These green dots contrast perfectly with the bright red dot at the front of the sight. These sights fit all holsters and are snag resistant. Also, the fiber is concealed and cannot be seen by your target.

In essence, these sights use TRUGLO’s traditional fiber optic technology. As such they are built for maximum performance and durability.

Best Night Sights For Glock 43 Buying Guide

So what should you consider at when looking for the Glock 43 ameriglo sights or sights from any other maker for that matter? There are a number of things to look at when shopping for your best Glock 43 sight. These are;

Size of the sight

The purpose of buying a sight is to aid you in aiming accurately. Therefore your sight should be large enough to spot whether at night or during the day. However, it should not be too large that it snags on the holster when you are removing your Glock.

Sime sights have serrated surfaces while others have smooth surfaces. Personally, I prefer those with a smooth surface. Reason being that a smooth surface is ideal for applying the tritium paint.

Though smooth surfaces are more prone to glare than their serrated surfaces, they offer a better surface for tritium paint.

Fiber optic vs tritium

For a sight to function at night it needs to be visible. And for it to be visible there needs to be some sort of light. In the absence of batteries, manufacturers have always opted for a chemical known as tritium.

Tritium is a radioactive isotope of hydrogen. Without getting into the boring chemistry of how it works, tritium paints glow in the dark without the need for batteries. This paint has been used on sights for years.

Fiber optic is a newer material that has made its way into night sights. Sights that use fiber optic rely on a fiber optic tube that lights up without the need for electrical power. Compared to tritium fiber optic does not last long.

However, fiber optic remains brightly visible even during the day. Also, with it, you have a wider selection of colors. So it really comes down to your preference. As I have already stated I prefer tritium as it can last for years without fading.


Though minimal the Glock 43 does have recoil and you will need a sight that can take a beating from the recoil. As such, the ideal sight is one made from either aluminum or steel. Plastic is a big No as it is more likely to break.

Also, aluminum and steel do not add much weight to the overall gun. Some sights come with added anti-rust coatings or finishes. Ideally, the more protected the sight the better.


Settling on one Glock 43 night sight to buy can be easier said than done. The market is flooded with all kinds of aftermarket sights for the Glock 43. Thus, identifying the best sights for Glock 43 will require some research. All the same, the best Glock 43 sight is the one that works best for you and meets your needs. Obviously different people have different needs.
