When Is It Time to Replace My Sights for Glock 17?

How do you know when the moment strikes to replace the sights for your Glock 17?

Here’s a quick way to tell:

Take your Glock to the gun range with a magazine of bullets and a clean target. Line up your sights with the bullseye and try to keep your form consistent. Shoot between five and ten shots every time. Once you’ve gone through the magazine, bring the target back and take a look.

If your sights are working accurately, your target should have multiple holes on or very close to the bullseye. If that’s now what you see on your target, chances are you should replace your sights.

Are Sights for Glock 17 Universal?

Yes, all Glock 17s will have universal sights that you can use or interchange on any Glock 17 model. You’ll just need to be sure that you’re purchasing a sight for a Glock 17 model specifically, as not all Glock sights are the same. 

As long as the Glock sight is for a model 19, 22, 23, 24, 26, 27, 33, 34, 35, 37, 38, or 39, and of course 17, they should fit.

What Should I Look for When Buying Sights for Glock 17?

Here’s what you should keep in mind:


You need to be able to see your sight, whether at night or during the day. Typically, you don’t need batteries for this, but tritium and fiber optic instead. Tritium is the better pick when given a choice as it lasts much longer – perhaps even a decade. 


As briefly mentioned before, it needs to be bright when it’s dark and light out. It all comes down to brightness. If not bright enough, you’ll still see the target at night, but the daylight will wash away the sight’s visibility.


Choose a model built from steel or aluminum metal, as these two materials will be able to withstand the recoil and abuse from consistent use. 

Alternatively, a polymer-made sight is lightweight but can’t offer you the same resistance and durability as the metal options.


Do you want to be able to draw it quickly for self-defense? Avoid anything that feels too clunky.

Will you be carrying the gun daily? Find a model that can withstand everyday use. 

Plan to spend the most time with it at the range? Pick one that lets you remain consistent even at long distances.

Review of the Best Sights for Glock 17

Now that you understand what to look for in sights for Glock 17 and how to know if it’s time to replace your sights let’s dive right into our reviews for the best sights for Glock 17 on the market today.

Top Pick

Trijicon HD XR Night Sight Set

Trijicon HD XR Night Sight Set, MOS Fit Rear, Glock 17, 17L, 19, 22, 23, 24, 25, 26, 27, 601092



What Recent Buyers Report

Most recent buyers report a significant upgrade in accuracy when switching to the Trijicon HD XR Night Sight Set. Trijicon sets the bar high, but recent buyers are delighted with the purchase as it lives up to the Trijicon standard, even with a price higher than others on the market.

Why It Stands Out to Us

This Trijicon HD XR Night Sight Set features an expanded field of view and enhanced front sight acquisition, making it easy to hit the target whether it’s day or night. It also features protective aluminum cylinders around the lamps and a silicone rubber cushion for durability and comfort. 

Its thinner sight post helps boost accuracy, even when shooting at further distances. Shot after shot, you’ll be impressed with the consistent precision. It’s why so many of the reviews for the product come from repeat buyers that have come back for more after years of reliable use.

Bottom Line

The Trijicon HD XR Night Sight Set is an essential sight for someone who tends to shoot at longer ranges and needs an expanded field of view while discharging, especially at night. Its slim profile and protective features keep it out of the way and safe from damage. However, if you tend to spend more time shooting at closer ranges during the day, it might not be the right fit.

Best Budget Option

Meprolight Glock Tru-Dot Night Sight

Glock Fixed Tru-Dot Night Sights for Models 17 19 22 23 24



What Recent Buyers Report

Recent buyers have nothing but positive things to say about the Meprolight Tru-Dot Night Sights. Most of them were repeat buyers returning to replace their sight after years of use – some even reported use for over a decade! 

Most reviewers rave about these sights’ brightness, especially during daytime conditions, where other sights often fail.

Why It Stands Out to Us

This sight with a self-illuminated light source (tritium) requires no batteries, making it always ready to go whenever you may need it. As one of the brightest sights available today, it operates well in all weather and lighting conditions and can transition from daytime to nighttime shooting seamlessly.

Once mounted, this sight is entirely maintenance-free and offers an increase of over 85% in hit accuracy. It’s no wonder there are over 4.5 Million systems in use around the world.

Bottom Line

This durable sight option is made up of durable materials built to last and a bright sight that you can’t miss even during the brightest (or darkest) conditions. Whether you enjoy shooting before the sun comes up or in the middle of the day, this sight would be an excellent purchase for anyone who wants to make a lasting investment.

Best Glock 17 Suppressor Sights

Trijicon Night Sight Sets for Glock Pistols

Trijicon GL601-C-600836 Night Sight,HD XR Orange Front Outline



What Recent Buyers Report

Recent buyers are praising the Trijicon HD Night Sights Set for its quick and bright action visible in low light or no light at all. They do note that to install the rear sights, you’ll need a special tool. 

However, they appreciate that these sights are much more robust than factory sight profiles.

Why It Stands Out to Us

This set of Glock 17 suppressor sights include three-dot iron sights that can improve your night-time shooting accuracy five times over when compared to conventional sights. 

This improvement comes from the unique design of these parts, which quicken front acquisition, even when lighting is transitional. 

They include a photoluminescent (glow in the dark) powder around the front ring to improve visibility and, when combined with the XL front dot, they make it easy to hit the target every time. 

These sights’ metal bodies are custom-made to fit this specific handgun for a premium fit and maximum durability.

Bottom Line

If you need more power and accuracy than what conventional sights can offer, it might be worth your while to give these suppressor sights a go. Thanks to photoluminescent paint, a wider U-shaped notch to guide your front sight focus, and the Trijicon unique design, this sights set may be able to give your shooting the boost it needs.

Best Glock 17 Night Sights

TRUGLO TFX Pro Tritium and Fiber Optic Xtreme Handgun Sights for Glock Pistols

TRUGLO TFX Pro Tritium and Fiber Optic Xtreme Handgun Sights for Glock Pistols, Glock 17/17L, 19, 22, 23, 24 and More



What Recent Buyers Report

One feature that recent buyers have loved is the combination of both fiber optic and tritium used for maximum visibility with this sight. They found the installation to feel intuitive and easy and have all seen an improvement in their focus, target acquisition, and accuracy.

Why It Stands Out to Us

If you want a gun sight for your Glock 17 that is virtually indestructible, this is it. The TFO (Tritium and fiber optics) protection fully encapsulates the light source, making it nearly impossible to damage.

On that note, it’s also impervious to chemicals, oils, cleaning solvents, and ultrasonic cleaners. 

This gun provides impressive visibility at night and moderate visibility during the day and uses a front-sight Focus-Lock for fast, precise shooting. It even has an angled rear-sight edge ideal for emergency operation with one hand.

This sight features a green rear light and a green with orange ring front light for maximum visibility.

Bottom Line

This sight offers impressive visibility at an approachable price and features the best of both worlds with tritium and fiber optics combined. Its construction is also resistant to almost all of the elements, making this a long-term investment in your protection.

TRUGLO TFX Tritium and Fiber-Optic Xtreme Handgun Sights for Glock Pistols

TRUGLO TFX Tritium and Fiber-Optic Xtreme Handgun Sights for Glock Pistols, Standard Height, Glock 17/17L, 19, 22, 23, 24 and more



What Recent Buyers Report

Recent buyers recognize that the X in “TFX” means that this model is built to handle and ward off just about any threat or condition. 

However, some are saying that the sights aren’t quite bright enough for daytime use. Interestingly enough, other buyers are saying that this sight is best used in the daytime as it doesn’t perform very well at night. This conflicting information makes it hard to know how it truly functions.

Why It Stands Out to Us

With fully encapsulated TFO technology, this sight is the first of its kind. To this day, it’s still the only one on the market with this kind of durability. The tritium is the powerhouse player at night, while the fiber optics work when a sight is needed in the daytime.

The concealed fiber sight also can’t be seen by the target, making it a stealthy tool to use when you don’t want to be noticed.

Bottom Line

If your top priority is a Glock 17 sight that will withstand all elements and last you for upwards of a decade, this could be it. While its performance in the day and night is questionable, the durability outweighs this concern for some.

Aspects to Consider Before Buying

These are the aspects you’ll need to consider before buying yourself a Glock 17 pistol sight:

Profile and Width of Front Side

Most come as a standard semi-ramp style with the blade facing away from the shooter for reduced snag. As far as width goes, a wider sight means less accuracy, especially in long-distance shots. Most shooters like a width of about .125 inches.

Type of Rear Sight

The factory default is two-dot sights, which help you focus on the front sight with accuracy. If you want a single-dog or triple-dot version, look for specifications of this in the product details.

Height of Sight Calculations

Make sure you can adjust the sight heights to match your target area.

Fiber Optics vs. Tritium

Tritium works best at night, while fiber optics perform better during the day time. Consider when you’ll be using the sight most before you settle on a material.


If it’s time to replace the sight for your Glock 17, take care during the buying process to ensure you end up with the right fit. Consider things like daytime vs. nighttime shooting, materials used in construction, and the type of illumination from the sight before choosing. Then, take a look at the options reviewed here, as these are some of the best on the market.

People Also Ask

Still, have questions regarding the best sights for Glock 17? You’re not alone. Here are answers to some of the most frequently asked questions regarding these sights.

Can you adjust the sights on a Glock 17?

Yes, they are all adjustable. You may need a tool to do it, but you can make small changes to the sights with enough effort.

Are stock Glock sights good?

Stock Glock sights are generally disliked because of their polymer construction instead of metal construction, which is more durable.
