What Makes Night Sights Great for a Glock 19?
If you use your Glock as a home defense pistol, a night sight is a must-have accessory. Here’s why you should upgrade your firearm with a night sight.
Accuracy
Because the Glock 19 is a popular pistol for home defense, it’s a firearm you are likely to use in a situation with little light available. A night sight with dots that glow in the dark will help you acquire your target regardless of how much light is available.
Muzzle Flash
When shooting in the dark or a low-light situation, the muzzle flash from your Glock can have a blinding effect.
While it would be challenging to use a traditional sight to place a second shot, a night sight will remain visible despite the muzzle flash thanks to its brightness and high contrast. It will help you get back on target quickly if you need to shoot again.

Lightweight
Night sight is a lightweight accessory. It won’t weigh down your pistol and won’t require you to adjust the way you hold your firearm.
Versatility
Even though night sights are best for shooting in low-light situations, the dots remain visible in the daytime. It’s a versatile accessory that you can use instead of your Glock’s factory sight in a wide range of settings.
Review of the Best Night Sights for Glock 19
The following accessories will improve your accuracy in low-light or no-light settings.
Best Overall:
Trijicon HD Night Sights Set
Pros
Cons
What Recent Buyers Report
This sight has received excellent reviews. People think this accessory helps with target acquisition and is easy to install. They like the durable design and think this low-profile sight is convenient.
Why it Stands Out to Us
You can’t go wrong with this sturdy and durable sight set. The rear sight features a classic U-shaped notch that guides your eye to the front sight naturally.
The rear sight uses a black outline and bright green or yellow tritium lamps. The front sight uses a green outline, and you can choose from orange or yellow tritium lamps.
The sight uses a sturdy aluminum casing to protect the tritium lamps. You can count on this sturdy exterior to protect the sight from shocks and recoil.
This set is an excellent option if you’re looking for brightness in a wide range of settings and want an accessory that is easy to install and intuitive to use.
Bottom Line
We like this sight set because of the quality of the construction and brightness of the tritium lamps. We also like the fact that you can choose between different colors if you don’t like the usual orange and green contrast.
Runner-up:
TruGlo Brite-Site TFX Pro Sight Set
Pros
Cons
What Recent Buyers Report
A majority of buyers are happy with their purchase. They like the look of the sight and say the orange outline is easy to see. The sight is bright and delivers good performance during the day and night, but some buyers say the sight could be brighter in low-light or shadows.
Why it Stands Out to Us
We recommend this sight set because of the high contrast of the green illumination and orange ring you will find on the front sight. The rear sight uses a U-notch design and features green tritium lamps.
There is a sealed capsule that protects the tritium lamps and extends their lifespan. The nitride finish is another feature that makes the sight set durable. The sealed capsule can withstand exposure to the elements and to cleaning solvents and other chemicals.
This sight set uses a more elongated design compared to other products. It helps create a more modern look for your Glock.
Bottom Line
This sight set stands out thanks to its sleek look, but it’s also an excellent option if you’re looking for a durable investment. We like the bright tritium lamps, the high contrast of the front sight, and the low-profile of the sights.
Best for the Money:
AmeriGlo Spartan Tactical Operator Sights for Glock
Pros
Cons
What Recent Buyers Report
People like this sight set because it’s easy to install and it’s compatible with most Glock models. Reviewers often mention the bright orange front sight that helps with fast target acquisition. A few buyers say brightness can be better in the daytime, but it’s not a significant issue.
Why it Stands Out to Us
This sight set from AmeriGlo is an ideal upgrade for your Glock if you want a sight with high visibility. The front sight uses green and orange tritium lamps for high contrast, and the rear sight uses a black outline to make the green tritium lamps more noticeable.
The rear sight uses a wide U-shaped notch. It’s perfect for guiding your eye to the front sight, and the wide design is convenient if you’re new to aiming with a sight.
Bottom Line
We recommend this sight set because of the brightness of the tritium lamps and the high contrast of the green and orange front sight. We also think the wide design of the rear sight could be a noteworthy feature for novice Glock owners.
Best Glock 19 Gen 4 Night Sights:
AmeriGlo Ghost Ring Night Sight Set
Pros
Cons
What Recent Buyers Report
People say this sight set is perfect for those with poor eyesight because of the aperture style rear sight. It’s easy to install and provides excellent visibility in a wide range of conditions. Buyers say they notice a difference when it comes to speed and accuracy after installing this accessory.
Why it Stands Out to Us
We like the ghost ring design of the rear sight because it guides your eye to the front sight more effectively than a U-shaped rear sight. This design is convenient if you have poor eyesight, lack experience, or use your Glock in low-light conditions.
The aperture style rear sight also helps with accuracy since you have to position your pistol to see your target through the ring.
The rear sight is highly visible thanks to the two green mini dots on the sides of the aperture. The front sight uses a classic green and orange contrast.
The main drawback of this sight set is that the aperture ring adds weight and bulk.
Bottom Line
We highly recommend this aperture style sight if you have bad eyesight or need a sight that helps with accuracy. We also like the brightness of the tritium lamps and the high contrast of the front sight.

XS Sight Systems F8 Night Sight
Pros
Cons
What Recent Buyers Report
People like the wide notch on the rear sight because it makes aiming easier. Reviewers also like the high contrast of the orange ring on the front sight. Most reviews mention how bright the sight is, and a lot of people like the small size of the dots since it helps with accuracy.
Why it Stands Out to Us
We recommend this night sight if you want an accessory that will help with accuracy. The rear sight features a wide notch that lets plenty of light in and helps with target acquisition.
There is a slight overhang on the rear sight to reduce glare in bright conditions and a ledge you can use to pull the slide back.
The front sight uses a bright tritium orange ring for optimal visibility. The front sight is taller than on other accessories. A tall front sight can be a drawback for conceal-carry, but it’s a feature that helps get an accurate shot.
The sight uses a two-dot design to help you tell the rear and front sight apart in low-light conditions. It’s also easy to install, and the machined steel construction makes this sight a durable investment.
Bottom Line
This durable night sight is an excellent addition to your Glock, thanks to its wide notch and high visibility. We recommend it because of the brightness of the tritium lamps and the convenient two-dot design.
How to Choose Night Sights for a Glock 19
Here are a few things to consider when choosing a night sight.
Low-Profile
The Glock 19 is a compact pistol. It features a comfortable and well-balanced design. It’s a common option for applications like home defense or conceal-carry because of this compact design.
Night sight is an accessory that can give you an edge when shooting at night, but you need to pick a low-profile accessory that won’t make carrying your Glock in a holster difficult. A tall sight can also be an issue if it catches on something when you draw your pistol.

Color
Look for a night sight with a color that is highly visible. Some sights use a combination of bright colors to create a contrast and help you spot the front sight dot faster.
Green dots are standard, but you can find sights with yellow or orange tritium lamps. If possible, choose a sight that uses a bright dot and contrasting outline for its front sight. A green and orange combination is ideal since these two colors form a strong contrast.
Front Sight
A good night sight should have a front sight that you can identify immediately. If the front sight uses dots that are too similar to the ones you can find on the rear sight, it could be challenging to tell the front and rear sight apart in the dark.
Choose a front sight with a bright outline in a different color, a larger dot, or another design element that makes it easy to identify.
What Are Night Sights?
Night sight sets come with a rear and front sight. Aligning the dots of the rear sight with the front sight will help you shoot with more accuracy.
What Are Tritium Night Sights?
Tritium night sights use tritium lamps to create bright dots. Tritium is a radioactive isotope of hydrogen that glows. It produces bright dots in the dark and doesn’t require any batteries. Tritium has a half-life of 12 years, which means your tritium night sight will gradually lose some of its brightness over the years.
What Are Night Sights Made of?
The bright dots are small lamps filled with tritium. The housing of a night sight typically uses stainless steel or aluminum to create a protective exterior.

How Do Night Sights Work?
Night sight sets include a rear sight that you install above the backplate. The rear sight typically has two bright dots and a notch in the middle.
When you aim, looking through this notch and aligning it with the bright dot of the front sight will improve your accuracy.
Using a night sight is simple. There is no need to turn the sight on or off since tritium is always bright, and the design of your night sight should help you align the dots quickly by making the front sight immediately noticeable.
What Do I Need to Know Before Buying Night Sights for a Glock 19?
Here are a few things you should know before purchasing a night sight for your Glock 19.
How To Install
You will have to install the new night sight yourself. It’s a simple process, but you will need to invest in a few tools. You will need a nut driver to remove the old front sight and a nylon punch to drop the rear sight in without damaging your Glock.
You might also have to make a few minor adjustments to get the sight to align. If you’ve never installed a sight before, it’s best to get some help from someone who has more experience.

How Long the Sight's Tritium Will Last
Tritium is a radioactive material, which means it decays over time. Tritium has a half-life of 12 years. Half the tritium atoms will decay over this time frame.
You will see your tritium night sight become less bright over the years. It will be half as bright after 12 years, but you should consider replacing it after seven or eight years to get a newer and brighter model.
You'll Have To Practice
Shooting with a night sight is something you need to work on, ideally in low-light conditions. You will need to practice aligning the dots until it becomes second nature.
Practicing is essential if you use your Glock as a home defense weapon. You need to be familiar with your pistol and night sight, so that target acquisition is a reflex.
Types of Night Sights for a Glock 19
There are different types of night sights to consider.
Three-Dot Night Sight
With a three-dot night sight, the rear sight has a bright dot on each side of the U-shaped notch. You can aim by aligning the front sight dot in the middle of the two rear sight dots.
It’s a simple system but using three dots means there is more information to process. It’s also essential to choose a sight where you can tell the front and rear sight dots apart easily.

Two-Dot Night Sight
With a two-dot model, the rear sight has only one dot underneath the U-shaped notch. Aligning two dots is faster, and there is less information to process.
A three-dot sight is best for novice Glock owners, but you should think about upgrading to a two-dot model once you gain some experience with using a night sight.
U-Shaped Notch
Most night sights have a rear sight with a U-shaped notch. The sides act as a frame with dots on it, and the depression in the middle helps you aim.
A night sight with a U-shaped notch is easy to use, and the low-profile is convenient if you carry your Glock in a holster.
Aperture-Style Rear Sight
You can find night sights that use a rear sight with a ring-shaped aperture. It’s not ideal if you carry your Glock in a holster, but finding your front sight through a ring can be easier if you have poor eyesight.
Glock 19 Night Sights – Comparison Overview
Let’s compare some of the popular manufacturers and options.
Glock Night Sights vs AmeriGlo
AmeriGlo is a popular brand of night sights. You can purchase sets or mix and match front and rear sights for a customized result.
AmeriGlo stands out from other manufacturers thanks to its color selection. You can find front sights with orange, yellow, or white outlines. You can also find rear sights with or without outlines.
This manufacturer has a diverse product line with some aperture-style rear sights, rear sights without dots, and sets with additional height to accommodate for a suppressor. You can expect quality products from this manufacturer, and night sights come with a 12-year warranty.

Glock Night Sights vs Trijicon
Trijicon is another option to consider for Glock night sights. This company acquired AmeriGlo a few years ago, but the two brands offer different product lines.
Trijicon night sights are less varied compared to AmeriGlo. You will mostly find rear sights with a classic U-shaped notch and a smaller selection of colors.
Trijicon offers some exciting features, like a hooked design that allows you to use your night sight to pull the slide of your Glock back with one hand. This manufacturer also uses a sealed design that protects the tritium lamps from cleaning solvents, and the sight features a rubber cushion to absorb shocks and recoil.
Night Sights vs Regular Sights for Glock 19
A regular sight is a good option if you don’t expect to shoot in low-light situations. We recommend upgrading the factory sight on your Glock because it uses polymer. The polymer construction is less durable than steel, and you can scratch your factory sight easily.
You can find red dot sights that improve visibility but keep in mind that a night sight is your best bet for shooting at night.
Night Sights vs Fiber Optic for Glock 19
A fiber optic sight is an alternative to consider if you want a bright sight for your Glock. Optical fiber can transmit light through a thin thread, which results in a precise sight.
You can find a wide selection of colors and diameters when shopping for fiber optic sights, and these accessories tend to be more affordable.
However, tritium night sights are more durable. While fiber optic sights provide more brightness in the daytime, a tritium sight is best for shooting at night.

Glock Night Sights Install
Here is what you will need to install a night sight on your Glock:
- Nylon punch

- Place the slide on its side into the vise, using a vise block if you don’t have a vise with soft jaws.
- Use the nylon punch and hammer to drive the old rear sight down.
- Drop the new rear sight in as far as you can, and use the nylon punch and hammer to drive it in.
- You might need to use sandpaper to file the rear sight if the fit is too tight.
- Try the new sight and make some small adjustments with the nylon punch and hammer if needed.
