We know, it is not a typical night sight, but this one is an excellent choice for its great low-light performance.

Things to Consider When Buying the Best Glock 43 Sights

Our list of reviews should already give you a couple of great options to consider for your next purchase. However, before you go ahead and choose one, there are a couple of key elements that you should know about.

Since a gun sight is an extension of your weapon, you do not want to make the wrong choice. Ending up with the wrong unit can mean all the difference between life and death in a high-stress situation.

The Glock 43 is a self-defense weapon, and you want to make sure that all the accessories are up to the task when it comes to your defense. To that end, here are a couple of things you should know about before you settle on a specific gun sight for your Glock 43.


The main reason behind getting a night sight is to ensure you hit your mark whenever you pull the trigger. So, getting a gun sight that does not offer perfect precision makes no sense. This is the first element you need to check thoroughly before you go for a specific unit.

In most cases, you want to test out the accuracy of the sight yourself by installing it on your Glock or a gun that you find in the store. If you are going with a well-known brand, accuracy adjustment should not be an issue. Most gun sights let you adjust the accuracy yourself to better suit your needs.


Night sights on guns typically come with front and rear sights that have tritium gas lamps in them. The brightness of the lamps will dictate how easy it is for you to acquire the target.

Although the lamps are white during daylight, as it darkens, the lamp should become illuminated in either blue, green, or yellow colors.

The best sights for Glock 43 will have contrasting colors to help you better adjust your aim. You should also see if the lamps have a white ring around them to help you get a better fix on the target.

As long as the lamps are bright enough, you should have no trouble aiming in poorly lit environments.

Size of the Gun Sight

The Glock 43 is a lightweight 9mm handgun suitable for concealed carry and self-defense. So, the last thing you want is to invest in a bulky night vision scope that will make it impossible to hide your weapon. It is critical to consider the overall size and design of the gun sight before you get it.

If you look at our list of reviews, all of the units we showcased feature a slim design that does not add anything extra to your weapon. You can keep the sights attached to your gun and can holster it easily under your shirt without any printing. When you are buying a night sight for Glock 43, make sure it leaves a small footprint.

Installation Difficulty

If you are a casual gun owner, you do not want to go with a complex gun sight. You want something simple that you can install yourself without going to a professional gunsmith. Even massive gun enthusiasts prefer a simple sight over a complicated one.

Thankfully, most gun sights are pretty easy to install and you can do it yourself. But there are some complex models out there that can be a hassle to install and adjust. And if you like swapping sights, it would be a nightmare working with a complicated night sight.

Construction and Durability

When it comes to factors you want to consider, durability is the most important one. After all, you do not want your gun sight to stop working after a couple of uses. A gun sight has to take a lot of abuse because of the recoil of the gun and the scratches when you pull it out of the holster.

So, you need to check and make sure that the material used in its construction is up to the mark. Typically, aluminum or metal gun sights are the best choices as they will be able to survive in any condition. Also, check the mounting mechanism of the holster to get an idea of its durability.


Are you a collector of guns? If so, then investing in a versatile gun sight is usually the better choice. That way, you will be able to swap out the sights between your gun effortlessly without having to buy a new one for each of them. A Glock 43 gunsight should at the very least be compatible with a Glock 42.

However, this can be a double-edged sword. Make sure you give priority to other important features like accuracy, or brightness before focusing on versatility. You need to make sure it works well for your Glock 43 before you check it out on other firearms.

Other Features

Apart from the key aspects, there are a couple of other features you might want to consider getting better value. For instance, the color of the lamps can play a role in your overall experience with the unit. Some prefer green lamps while others may get a better aim from yellow lamps.

You can also find a few dot laser night sights in the market that can give you excellent performance in low-light conditions. Although they are quite different, the effect they give is pretty much the same. So, if you want, you can even go with a laser sight for your Glock 43.


The price of a good night sight for Glock 43 can vary wildly. Brands such as Trijicon, or AmeriGlo are good examples of good quality and high price. But you might not need to get the most expensive sight in the market for a good performance and accuracy from your handgun.

In our list, you will find a few budget-friendly models that offer exceptional value for the price. If you are on a tight budget and do not want to spend any extra dime, those options might be better for you. Going over your budget typically is not a smart move when buying something.

What are the Benefits of Using a Glock 43 with Night Sights?

If you are still on the fence about investing in a night sight for your Glock pistol, then the following section is for you. Sure, installing a night sight can be expensive depending on which model you buy. But the vast advantages it brings to your shooting skill far outweigh the small setback.

Here we will give you a brief overview of all the benefits you can get by installing a night sight on your Glock 43.

1. Less Muzzle Flash Issues

A muzzle flash can cause dizziness due to the sudden flash of light when shooting in the dark. With night sight, the contrasting colors on the sight can offset this issue to some degrees.

2. Better Accuracy

The obvious advantage of installing a night sight is getting a better accuracy than factory sights. However, make sure you properly calibrate the sight so that the projectile from your gun will hit where the sight is pointing. Poor calibration on even a high-quality gun sight will mean a missed shot.

3. Low Light Shooting

Shooting in low light conditions is no longer a problem if you have a night sight equipped on your Glock 43. The tritium gas lamps that usually come on the night sights get illuminated in the darkness. With this, you will be able to aim precisely at the target in a matter of seconds.

4. Also Works as A Normal Gun Sight

Night sight is not exclusive to low-light shooting. During daytime, your night sight will work perfectly as a normal gun sight. The gas lamps are activated automatically based on ambient light. If you are aiming in a well-lit environment, the lamps will not be illuminated.

Frequently Asked Questions

1. How long does the tritium in gas lamps last?

Typically, tritium in the gas lamps stays illuminated for a long time. It has a half-life of 12 years which means after a decade, the lamp will only be half dimmer.

2. Which sights can I use on my Glock 43?

Before you buy any gun sight, you should consult the product specifications. Whether your Glock 43 is compatible with a specific sight should be listed there. As a rule of thumb, any sight that works with Glock 42 will also work in Glock 43.

3. Is it hard to install a night sight on a Glock 43?

Not really. As long as you have some basic gunsmithing knowledge you should be able to do it yourself. However, if you are not fully comfortable with it, you should take it to a professional for proper calibration. Without perfect calibration, your sight will not give you the perfect accuracy.

4. How do I aim using the night sight?

Aiming with a night sight is not very complicated regardless of the weapon of your choice. The typical design of these sights is 2:1. This means the front sight has a single dot while the rear sight has two dots on two sides. Before anything else, make sure your sights are properly calibrated.

When you raise your weapon, you should focus on the front sight. The front sight dot should be between the two rear sight dots. When all the sights are properly aligned and meet the target, this means you will be able to hit that target when pulling the trigger.

Final Thoughts

The simplest way to upgrade your Glock 43 is to install a high-quality night sight. Since the factory sight that comes with this weapon is not that great, you will notice the benefits of your new sight almost instantly. It would drastically improve your shooting accuracy.

We hope our article on the best night sights for Glock 43 could help you figure out which unit you want to buy for your handgun.
