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.
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 17, 19, 22, 23, 24, 26, 27, 33, 34, 35, 37, 38, or 39, they should fit.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
These are the aspects you’ll need to consider before buying yourself a Glock 17 pistol sight:
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.
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.
Make sure you can adjust the sight heights to match your target area.
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.
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.
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.
Stock Glock sights are generally disliked because of their polymer construction instead of metal construction, which is more durable.
