The Best Aftermarket Glock Sights: Elevate Your Accuracy

There is no arguing that Glock makes some fantastic firearms. If you’re reading this article, I’m willing to bet you even have one yourself. However, one thing that I and many others have complained about is the stock sights that come on your standard Glock. 

As much as I fall into the “if it ain’t broke, don’t fix it” crowd, that doesn’t mean certain things can’t see drastic improvements. The OEM Glock sights are definitely one of those things. 

Whether your goal is to improve your target acquisition speed, accuracy, or low-light capabilities, replacing your Glock’s sights can help you achieve it.

What To Look For

When choosing your next set of sights, there are plenty of considerations to take into account. 

Height

If you don’t plan to shoot with an optic or suppressor, you can go ahead and skip to the next section. However, if you do, you will need to make sure to order your sights accordingly. 

Suppressor height sights are going to be the tallest and allow you to…you guessed it, use your sights over top of your suppressor. 

Even if you don’t currently have an optic or suppressor but think you may get one, it doesn’t hurt to order taller sights just in case. Keep in mind that when you order a holster, though, you’ll have to check that it is compatible with taller sights. 

Shape

Your OEM Glock sights feature a square-notch rear sight, but that doesn’t mean you have to stick with that style. You can also find rear sights that feature a v-notch or u-notch. I suggest heading to your local range and seeing if they have any for rent with these styles of sights to see which works best for you. 

Tritrium or Fiber Optics 

One of my favorite reasons to upgrade sights is to enhance your abilities in low-light scenarios. Tritium and fiber optics have been used in sights for many years and have come a long way.

Between the two, I will almost always recommend tritium, which remains bright in low and no-light scenarios. It’s not as bright in daylight as fiber optic tubes, but if you’re aiming to improve your low-light readiness, stick with tritium.  

Price

Last but not least, you should consider the price. While iron sights are small and don’t look to be that expensive, some can run a couple hundred dollars for the set. It’s better to choose carefully and buy once than to rush and have to replace them multiple times. 

How I Chose The Best Sights

I’ve been shooting Glocks and other pistols for the better part of two decades, with very few of them remaining “stock” for very long. I’ve replaced dozens upon dozens of my own sights over the years and have shot countless others. 

These recommendations come first and foremost from my personal experience. I’m also lucky enough to do this for a living, so I’ve spoken with many industry peers regarding their favorite sights. 

At the end of the day, it does come down to personal preference, but the following recommendations are a great place to start your search!

The Top Choices

Best Overall Sights – Trijicon HD 

Trijicon makes some of the most trusted and popular duty-grade sights on the market. 

The HD night sights have everything you need plus more. Structurally, they are some of the toughest out there and feature a U-notch rear sight that is serrated to reduce glare. The rear sight is also steeply hooked in the front to allow the shooter to perform one-handed slide operation. 

You’ll find three bright green tritium lamps inserted in the sights, with varying photoluminescent paint colors around each one, depending on which you order. You never have to worry about the tritium dying on you either, as each lamp is warranted for 12 years. 

I’ve found these sights to improve not only low-light sight picture but also overall target acquisition speed. 

They are on the pricey side, but you definitely get what you pay for.

Best Suppressor Height Sights – Night Fision 

Night Fision may not have as long of a proven track record as Trijicon, but the one it does is sure impressive. 

It took the market by storm in 2017 and never looked back. Night Fision offers some of the brightest tritium I’ve ever seen in a set of pistol sights, and the fit and finish are truly top-notch. 

If you happen to shoot suppressed, these are the sights for you! They are CNC machined out of high-quality steel and finished with a black nitride coating for superior corrosion resistance. 

You’ll be able to choose from several ring color options, or if you prefer a blacked-out rear sight, you can go that route as well. 

These sights don’t break the bank and are ready to help take your suppressed shooting to the next level.

Best Budget Sights – TRUGLO Tritium X

You wouldn’t be able to tell from simply looking at the TRUGLO Tritium X sights but these can often be found just under $50. 

Despite the low price, these are constructed from solid steel and treated with a nitride finish for enhanced durability. They utilize Swiss tritium, which is known for its bright glow and is often found in more expensive sights. 

The snag-free design works well with most standard holsters and is well-appreciated by those who enjoy dry firing often.

Best Optic – Holosun SCS-MOS

If you’re more concerned with adding an optic to your Glock than replacing the sights, the Holosun SCS-MOS is my top recommendation. 

Holosun continues to lead the pack from an innovation standpoint, and this optic encompasses much of what it offers. The solar charging system can essentially operate the optic indefinitely, there are multiple reticle options, and the sight automatically adjusts its brightness. 

It’s a direct mounting optic made specifically for the Glock platform, which means no ugly adaptor plates and no need to upgrade to taller sights. 

While there are many great optics on the market, this has been and will continue to be my go-to for my Glock 19 for the foreseeable future.

Final Thoughts 

Remember, what sights may work best for the guy in the shooting lane next to you may not be best suited for you. So, consider what your end goal is in replacing your sights and begin your search accordingly. 

Thankfully, sights are not difficult to switch should you buy some and wind up not liking them. If you aren’t confident in swapping out your sights yourself, you can always take them to a gunsmith who should be able to do it quickly and inexpensively. 

As always, stay safe, train hard, and have fun.
