What Purpose Do aftermarket Sights for Glock 19 Serve?

A sight for a Glock 19 serves quite a few purposes to help you when using your gun.


When using a firearm, one of the most important factors is accuracy. If you’re going to shoot, you want to make sure you hit your mark. To do otherwise could be dangerous or even fatal.

Many users find the sights that come with the Glock 19 to be insufficient, making the gun less effective. An aftermarket sight can improve your accuracy and help you use your gun safely.

Accounting for Changes

Once you pull the trigger, several factors affect the direction of the bullet. Gravity, angle, type of load, and more all play a role in where the bullet will go. While you can’t control many of these factors, you can use a sight to ensure the bullet goes exactly where you want it to.

Nighttime Visibility 

Shooting a gun at night can be challenging. The dark makes it difficult to see, and the last thing you want is to pull the trigger with no clue where you’re aiming. A night sight can help you to be precise, even in the pitch black.

Is it hard to learn how to install/use aftermarket sights?

Fortunately, it’s easy to install and use aftermarket sights on your Glock 19. Once you install the sight properly, your Glock is easier to aim and you can shoot with more precision. Your sights should come with instructions for installation, and some sights even come with some of the tools you’ll need.

There are different ways to use your sights, but most people prefer the “point of aim, point of impact method.” For this method, you line up your target with the upper part of the front sight.

How to Choose New Sights for Glock 19

Choosing a sight for your Glock 19 can be confusing, as there are so many products on the market. Follow these guidelines to pick the best sight for your needs.


Some sights have a lower profile. A lower profile lets you holster your gun with ease and helps with concealment. If you need to use your gun for concealed carry, consider a low-profile sight.


You may prefer a black or dark-colored sight to fit in with the aesthetic of your gun or if you have trouble seeing green sights. But, if you’ll be using your gun in low light or the dark, you may want to choose a colored sight. A brighter color makes it easier to use your sight at nighttime.

Profile and Width of Front Sight

You’ll usually choose a semi-ramp profile, and you may opt for a serrated profile to help reduce glare. Front sight width plays a significant role in accuracy. Narrow front sights are more accurate, but are also more challenging for an inexperienced shooter.

Use of Tritium

Tritium is a convenient substance, as it’s radioactive and glows on its own. It’s becoming popular for use in sights because you don’t need to charge your sight or rely on batteries.

Fiber Optics

If you plan on shooting during the day, fiber-optic inserts are easy to see even in bright sunlight.

Review of the Best Sights for Glock 19

Below are five of our top picks for best sights for Glock 19. We’ve chosen our favorites for different situations to help you find the one that fits your needs.

Top Pick

Lasermax Guide Rod Laser Sight for Glock Pistols



What Recent Buyers Report

Recent buyers like that this sight is already aligned and that they can activate it with either the right or left hand. They also appreciate how accurate the laser is, even at a distance.

Why It Stands Out to Us

There are a few things that make this sight stand out. First, it’s incredibly easy to install, so even if you’re new to using a firearm, you shouldn’t have trouble getting it on. Second, it’s completely internal, so you don’t add any bulk to your gun. If you use your gun for concealed carry, this laser is ideal.

Bottom Line

Omit, the Lasermax Guide Rod has everything you need in a sight for everyday use. It doesn’t alter the profile of your gun and it makes it much more accurate.

Best Night Sights for Glock 19

TruGlo Brite-Site TFX Pro Sight Set for Glock



What Recent Buyers Report

Recent buyers like that the TruGlo is so bright for better night visibility. They also appreciate that it’s easy to install.

Why It Stands Out to Us

This sight works well both in brighter light and low light situations. The color contrasts make it easy to focus accurately and quickly, which is precisely what you want when using a gun for self-defense.

Bottom Line

If you use your gun for self-defense, you need to be able to aim quickly and accurately in any type of condition, as you never know when you may need to use it. When your safety is at risk, you must move quickly, and the TruGlo Brite-Site uses both fiber optics and tritium to ensure that you can see both day and night – which is why we picked this as the best night sight for Glock 19.

Best Laser Sights for Glock 19

LaserMax Gen. 4 Guide Rod Red Laser Sight for Glocks



What Recent Buyers Report

Recent buyers like that this sight is easy to install and doesn’t force them to buy a larger holster. Most found the laser to be bright enough, but some wished that they could adjust it. The concept of putting a laser in the guide rod impressed many users. They found it to be an effective option.

Why It Stands Out to Us

We like that this laser sight is so well-made and that it comes with impressive durability qualifications. It’s easy to install and won’t alter the profile of your gun, making it a versatile option.

Bottom Line

If you’re looking for a laser sight, you can’t go wrong with the Lasermax Guide Rod Red Laser. It’s durable and easy to use. It is also a nice step above the standard Glock 19 sight and will give you improved accuracy and speed.

Best Budget Option

TruGlo Fiber Optic Sights




What Recent Buyers Report

Customers rave that this sight has larger diameter tubes, making it easier to use and brighter. Many users also love that this sight is an excellent option for this price point. Other than a few isolated cases, the majority of users have nothing but good things to say about it.

Why It Stands Out to Us

We love that this is such an incredible sight for such a low price. It’s great for those who are new to shooting and has some premium features, like larger tubes and bright fiber optics. If you’re in the market for a sight that you’ll mostly use in the daytime, this one is an ideal option.

Bottom Line

If you’re on a budget, you can’t go wrong with the TruGlo Fiber Optic Sight. You can use this sight in low-light conditions without giving away your location. It’s easy to install and use, and since it doesn’t need batteries, it’s ready to go whenever you need it.

Crimson Trace Laserguard for Glock



What Recent Buyers Report

Users like that this laser comes ready to use and that the red light is less conspicuous than the green light. Some users love the activation on the front, while others find it difficult to turn it on and off.

Why It Stands Out to Us

This sight is Crimson Trace’s first sight that users can install, yet it still has the quality of a professional sight. You don’t have to do any modifications to your gun to install it, and the red light helps you find your target without giving away your location. This laser sight is ideal for use at nighttime.

Bottom Line

If you’re a more experienced marksman and you want a sight that allows you more flexibility, you’ll like the Crimson Trace Laserguard. You can adjust the laser as you see fit. There is a bit of a learning curve for installation and use, but once you get the hang of it, you’ll love the accuracy and control you have when shooting.

Advantages of Investing in a Quality Sight for Glock 19

There are several advantages to investing in a quality sight for your Glock 19.

Aftermarket Sights Are Better

While many people love the Glock 19, one of the biggest complaints is that the sight that comes standard with the gun isn’t the best. Fortunately, the Glock 19 has been out for a while, and many companies have released some great aftermarket products.


No matter how good of a marksman you are, you can always be better with a great sight. By getting a quality sight for your Glock 19 and aligning it properly, you can improve your precision.


When it comes to owning a gun, nothing is more important than safety. Since the Glock 19’s standard sight isn’t the best, it’s well worth investing in a better sight to make your gun safer.

Better Visibility

Whether you’re shooting during the day or in low light, the right sight can give you better visibility. During the day, a sight can cut down on glare and can stand out even in bright sunlight. At nighttime, a sight with some color can show up in the dark.


Once you choose the right sight for your Glock 19 and install it, you’ll love how much more accurate you can be. With increased visibility and better accuracy, you can use your gun safely and with precision.
