Glock suppressor sights are a necessity for everyone who likes to shoot their handgun with a suppressor on. They guarantee that the sight picture isn’t blocked and that you can see your target clearly.

These sights are usually raised to compensate for the diameter of the suppressor. This means that they can also be used with an optical sight, such as a red dot, to co-witness or to act as a failsafe.

Choosing the correct Glock suppressor sight is important as you need a sight that will both clear your suppressor and give you an enjoyable and reliable shooting experience. The wrong suppressor sight will not clear your suppressor and offer other unaccounted for drawbacks, such as not fitting in your holster or not being able to co-witness with your other optical sights.

You also need a Glock suppressor sight that is compatible with your Glock model[1]

In this article I am going to review at some of the most popular Glock suppressor sights, so you can find the right suppressor sight for your use case.

Let’s get started, then.

The Best Glock Suppressor Sights Product Review

Our Pick
Trijicon Glock Suppressor Night Sight Set

Trijicon Glock Suppressor Night Sight Set

Easy to see in low-light situations. Sturdy build. Compatible with a high number of Glock models

View on OpticsPlanet View on Amazon

The Trijicon Glock Supressor Night Sight Set is a three-dotted height iron sight set adequate for no-light and low-light situations thanks to its tritium phosphor lamps.

Like most height sights, this Trijicon set is meant to be used with a suppressed pistol. However, it can also be used as a back-up sight for red dot users.

Build-quality wise, these sights have a metal body and a silicon rubber cushion. It seems resistant (it definitely feels sturdy) and is very lightweight.

There are three tritium phosphor lamps in the iron sights, two at the rear and one at the front. These lamps are what make this set ideal for night-time use — users can quickly acquire their target without having to use any batteries. The rear lamps are orange, and the front lamp is green, which supposedly (at least according to Trijicon) increases night-time accuracy by as much as five times over standard sights.

Five times might be a bit too much, but there is little doubt that these sights are easy to see in dim-light situations. Even when it is completely dark, the tritium phosphor lights emit a faint glow which your eyes quickly pick up on.

The lamps are encased in protective aluminum cylinders, cushioned by rubber padding. However, for Trijicon that’s not enough — the lamps are capped by sapphire windows, which protect them from punctures and distribute the light for an even luminescence in the entire visible part of the lamp.

These sights will fit most Glock models. They are compatible with Glocks 17 to 39, with the exception of Glock 28.

Does this suppressor sight fit the Glock40 MOS 10mm?

Yes, it does.

Is this suppressor sight an authentic Trijicon sight?

Yes. The Trijicon Glock Suppressor Night Sight Set is an authentic sight set from Trijicon.

Can these sights be used with a Vortex Venom?

Yes. These sights co-witness perfectly with the Vortex Venom.

Do these sights come with a screw for the front sight?

Yes. The screws are included in the package.

AmeriGlo GL-329 3Dot Tritium — Glock 19 suppressor sights

AmeriGlo GL-329 3Dot Tritium — Glock 19 suppressor sights

Great quality for the price. Excellent in low-light situations. Very versatile.

View on OpticsPlanet View on Amazon

The AmeriGlo GL-329 are one of the most versatile Glock suppressor sights — they fit every Glock model, except Glock 42 and Glock 43. Although iron sights aren’t something you change all the time, it is nice to know that they can fit in several of your Glock handguns.

AmeriGlo knows what works and sticks with it. The GL-329 has no fancy lights — the tritium phosphor lamps have a classic green color, which makes them very easy to see in low-light conditions.

One thing that should be noted though, is that you definitely need to use Loctite threadlocker glue, or else the sight will become loose when shooting. It is recommended you use threadlocker in most aftermarket iron sights, but you really need to use it with the AmeriGlo GL-329. Thankfully, it shouldn’t be too much of a hassle if you install your own sights.

Although the build is not as sturdy as the Trijicon, the AmeriGlo GL-329 is also not as expensive. The lamps are great for night-time use and with enough threadlocker you will barely notice any flimsiness.

The rear sight is .310”-high and the front sight is .314”. While these are great and very affordable sights, make sure they will have enough clearance for your Glock suppressor.

Can these sights co-witness with a Vortex Venom red dot sight?

Unfortunately, no. These sights sit at the same height as the Vortex Venom, therefor they do not co-witness.

Will these sights clear a Silencerco Ospyrey silencer?

Yes. They should clear a standard-size silencer without any problem.

How wide are these sights?

The front sight is .140” wide. The AmeriGlo GL-329 has a .150” notch.

XS SIGHT SYSTEMS GL-0004S-5 DXT Big Dot — Glock 17 suppressor sights

XS SIGHT SYSTEMS GL-0004S-5 DXT Big Dot — Glock 17 suppressor sights

V-shaped notch provides large field of view. Snag-free design increases drawing and holstering speed.

View on OpticsPlanet View on Amazon

The XS Sight Systems GL-0004S-6 DXT Big Dot have a low profile and a big V-notch that allows for a large field of view.

Their low profile might make them seem like the sights won’t clear most suppressors, but they work great with most standard suppressors and can even co-witness with most of the popular red dot optics.

The great thing about the low profile of these sights is that it allows for a snag-free design. If you are at all interested in drawing and holstering speed, then these Glock suppressor sights are a great choice for you. This snag-free design works with most of the holsters on the market.

The GL-0004S-6 DXT has a simple, but reliable design. The steel body has two tritium lamps (one at the front and one at the rear) that emit a tritium-green light. Unlike other sights, the GL-0004S-6 only has one lamp at the rear — it is positioned in the middle of the sight and it pairs nicely with the large white dotted lamp on the front sight.

You should have no problems acquiring targets during the night with these sights, even though its design is not the most appealing — I prefer the classic 2-1 lamp approach, but it’s completely relative. Despite what you might prefer, there’s no denying that this is a fast iron sight, great for night-time shooting.

What comes included in the box?

This XS Sight System Glock suppressor sight[2] comes with a red lock tight, a 0.5 Allen key, a nylon drift punch, and a front sight tool.

Do these sights co-witness with a Vortex Venom?

Yes. These work perfectly with a Vortex Venom or a Leupold Delta Point.

Truglo Glock Suppressor High Set

Truglo Glock Suppressor High Set

One of the brightest sets available. Snag-free design. Sturdy construction.

View on OpticsPlanet View on Amazon

First of all, one thing you should immediately know about the sights of this Glock Suppressor set: they sit very high. The good part is that they will easily clear most suppressors, the bad part is that the sights will stick out like a sore thumb.

Although these sights are high, they should still clear most holsters just fine — but you should note that it won’t clear every holster. Some holsters will just be too small for these sights.

And the sticking out part isn’t just about the height of the sights: the tritium lamps have an almost-nuclear shine to them. During day light the tritium lamps are immensely bright and will catch everyone’s attention. But this brightness comes in handy during the night — this is one of the brightest Glock Suppressor sights available.

Visibility is great in both daylight and low-light situations. Target acquisition remains fast, regardless of how much light there is. The TFX sealed-capsule design guarantees that the tritium will remain bright and spotless for a long time.

These sights also have a snag-free design, which is great for both holstering and drawing speed — assuming you can get it to fit in your holster.

Will this sight clear a concealment holster?

Yes. Although this set has a high front sight, it still clears most holsters without any problems.

What are these sights made of?

These sights have a metal body.

Will these sights co-witness with a Vortex Viper?

Unfortunately, due to their low-profile, these sights will not co-witness with a Vortex Viper.

Ameriglo Tritium Front Rear Tall Suppressor Set — Glock MOS suppressor sights

Ameriglo Tritium Front Rear Tall Suppressor Set — Glock MOS suppressor sights

Very tall. Relatively cheap.

View on OpticsPlanet View on Amazon

The AmeriGlo Tritium Front Rear Tall Suppressor Set is a simple tall sight set, with one single tritium lamp. This is a cheap way of adding extra height to your Glock pistol — but there are probably better options out there.

These sights are very tall and will easily clear any suppressor. The large white dot and the single tritium lamp on the front sight allow for some quick target acquisition and offer good visibility — however, this could be faster and smoother if there were three (or even two) tritium lamps.

In the dark, you want to be able to immediately see your sights, so you can focus on your target. While you can perfectly see the frontal tritium lamp, you might need a few extra seconds to align it with the rear sights. This would not happen if the rear sights also had some type of illumination.

Still, if you’re just interested in clearing your suppressor and don’t really care about night visibility, then this is a strong option. These sights are taller than most sights on this list and should have no problem with most standard (and even larger) suppressors.

The problem is that due to their height, these sights will not co-witness with some of the most popular red dot sights. If you are interested in co-witnessing sights, then these sights are probably not for you.

For the money, there are better options out there. You should only get these sights if height is really the only thing that matters to you.

Will the Front Rear Tall Set co-witness with a Vortex Viper?

Sadly, these sights are too tall to be able to co-witness with the Viper red dot.

How tall are these sights?

The front sight is .315-inches tall. The rear sights are .394 inches.

Do these sights work with a Burris FastFire?

Although they do not co-witness with Vortex Viper red dots, I have found that they co-witness perfectly with the Burris FastFire 3.

Buyer’s Guide

What are suppressor sights?

Suppressor sights, often also called “suppressor height sights”, are sights specifically engineered to be used with suppressors.

Since most suppressors have a large diameter, they often block the sight picture of your pistol. This means that looking through the standard pistol iron sights will result in not being able to see your target — your line of sight is blocked by the suppressor.

Suppressor sights have extra height to compensate for the large suppressor diameter — this is why they are also called “height sights”. With a suppressor sight, the sight picture is no longer blocked by the suppressor and you can clearly see your target.

Most suppressor height sights can also be used with other pistol optics. In cases where optical sights are used (assuming they are correctly zeroed), suppressor iron sights are used as a backup sight.

Suppressor sights commonly use tritium lamps that are visible in low-light situations. Besides being excellent backup sights, these types of sights are also great to use in low-visibility environments.

How to install Glock suppressor sights?

Most gun stores will install your suppressor sights for a fee. However, if you are so inclined, you can also install the sights on your own.

There are two main methods of installing suppressor sights: the professional method and the cheap method.

The Professional Method

The professional method requires having a front sight tool, a rear sight tool and a type of glue, usually Loctite threadlocker.

The first step in this method is to disassemble the pistol. Obviously, you should only do so after performing a safety check. In case you don’t know how to perform a safety check and how to disassemble your pistol, you should probably just pay the fee. Alternatively, YouTube is a great resource to learn how to disassemble most pistols.

After disassembling the pistol, you need to choose whether you want to install the front or the rear sights first.

To install the front sights, you will need a front sight tool to remove the hex nut from the slide. If the nut seems stuck, you can use a pair of pliers to help — be careful not to damage the nut or the slide.

After the nut is removed, you simply remove the sight and install the new one, tightening the nut again. You should be careful when tightening the nut, as too much pressure can damage the sight. Threadlocker glue will guarantee that the sight stays in place even when firing.

Installing the rear sight is also easy. Slide the sight tool to the rear sight and use it to push the sight out of the groove. Do not worry if it seems like the sight is stuck — it can take quite a bit of force before the sight slides out of the groove.

Once you remove the old sight, simply put the new sight into place. Push it in as far as you can with your hands and make sure to keep it level.

After both sights are installed you can reassemble the pistol. Take it to the firing range and test your new sights to be sure that the sights are correctly adjusted.

The Cheap Method

If you do not want to buy sight tools, there is an affordable way to install your Glock suppressor sights. You will need a nut driver, a nylon punch, a vice with soft jaws, and a hammer.

The first step is the same as in the professional method. To install new sights, you will first need to remove the old ones — and to do that you first must disassemble your pistol.

Installing the front sights with the cheap method is similar to installing them with the professional method. The main difference is that you will be using the nut driver instead of the sight tool.

Just be careful not to tight the sight too much with the nut driver — you might break it.

The rear sight is where things get tricky. You will need to lock your pistol into place with the vice (the soft jaws guarantee you don’t damage the pistol) so there is no unwarranted movement to complicate the process.

Place the nylon drift as close as possible to the base of the rear sight and use the hammer to give it a solid blow. A light hammer will prevent any damage to the gun. If you are unsure on how much strength to use, start soft and gradually increase the strength of your blow — you don’t want to damage the pistol.

Once you manage to remove the rear sights, slot the new ones into place. Gently tap it with the hammer to make sure the sights are in place and perfectly vertical.

After installing both sights, reassemble the pistol and go try out your new sights in the firing range.

How tall are Glock suppressor sights?

Glock suppressor sights height

There are quite a few different heights available, to accommodate every type of pistol suppressor.

The most common Glock suppressor sights are .315”-high at the front and .394”-high at the rear[3] These heights are enough to compensate for the diameter of a standard suppressor.

If you use larger-than-average suppressors, then these sights might not be high enough. There are sets that are .350”-high at the front and .429”-high at the rear. If that’s not high enough, Glock suppressor sights can reach a height of 0.365” at the front and .451” at the rear.

If you don’t know which height is the proper one for you, check your suppressor manual for the recommended sight height.


The right Glock suppressor sight for you will depend on a variety of factors. It must be both compatible with your Glock model, as well as high enough to clear your suppressor. Things get extra complicated if you also wish to use it as a co-witness for an optical sight.

This means that there is no “best” Glock suppressor, as it is a very personal choice. However, there are a few suppressors which I feel are good enough to recommend them to most users.

The AmeriGlo GL-329 is an easy recommendation. It fits almost every Glock out there and it offers an excellent quality for its price.

Of course, you should make sure that it clears your suppressor and that it is compatible with your specific handgun.

If you want something a little more durable, then you should consider the Trijicon Night Set. It has a very sturdy build, and it is an all-around excellent choice.

Let me know which is your favorite Glock suppressor sight and why.
