The Glock 9mm (specifically the 19) is the most owned Glock model in the United States. The Glock 9mm pistol sees service with home defenders, concealed carriers, and even police and military units worldwide. It’s a well-made, and the compact/subcompact models are both easy to carry and use.
Is the Glock the Perfect Handgun? Glock would say so, but most shooters agree there are a few changes that need to be made. Primarily the sights on most stock Glocks leave room for improvement. They are made of weak polymer, and use an odd U shaped design. Just like when picking out an optic for your AR-15, when it comes to picking the best Glock sights, it’s hard to differentiate the good from the bad.
Outside of the sights on a Glock, any other customizations (and there are many, including custom backstraps) are just personal preference. You have a wide variety of different options for sights. This is due to the Glock’s popularity. The aftermarket is massive, and the you have dozens of different options. The three following sights are what we consider to be the best Glock sights for 9mm handguns on the market today.
Trijicon HD Night Sights
XS Big Dot
TRUGLOW Night Sights
Now that you’ve seen a break down of our 3 favorites in the comparison chart above, let’s dive just a little bit deeper into each sight so you can decide which one should accompany your Glock.
9mm Glock Sight Buyer’s Guide:
Let’s be honest, the stock sights included on Glock pistols from the factory aren’t perfect. They are can be unusable in all but the closest of “bad breath” encounters. For starters, they are plastic with painted on epoxy. This isn’t the epitome of durability were talking about.
Secondly, the geometry of the sights make it counterintuitive for the human eye to line up accurately. What I mean by this is the U shape rear combined with the solid I shaped front sight can lead to optical confusion were trying to shoot quickly.
Tame and experience has proven that 3 dot sights are superior in almost every way to U notch sights in everything but bull’s-eye shooting. However, Glocks are not normally used for bull’s-eye shooting and if you’re thinking of upgrading your sights for self-defense are concealed carry you’re going to want to avoid U notch sights.
Glock pistols enjoy some of the most ubiquitous and prolific accessories on the firearms market. There is literally a gun shop, and a gunsmith, in every town of America that can recommend and install high-quality sights on your Glock pistol. All you have to do is pick them out.
1. Night vs. Day
Night sights are normally defined as any pistol sight that is able to be used in the dark. This is always a good thing, but you need to make sure you get the right kind because not all-night sights are created equal. As a general rule, throw away the night sights that Glock includes from the factory. They are not self-illuminating, and that is extremely important.
Any gun used for self-defense, and especially conceal carry, needs to have night sights. However, those night sights need to be a self-illuminating technology like tritium. Tritium sights are easy to find and are made by almost all major manufacturers. There even companies making combination fiber-optic tritium sights is that you can see fiber optics in complete darkness.
Just don’t cheap out on these, the vials that hold in the tritium gas need to be rugged enough so that they don’t break if you drop your gun or slam it against a door frame or furniture while carrying.
The reason behind having self-illuminating sights is simple, you may find yourself in a situation with regular glow-in-the-dark sights where it’s too dark to see your sights, but not dark enough to make them glow.
Worse, you could be under a streetlight and your target could be in the shadows and your sights will not be illuminated. You be able to see them because you’ve got light, but you won’t be able to make out your sight picture against a dark backdrop. Tritium night sights fix this by always blowing no matter what lighting condition they’re in.
2. How to Choose the Right Sight
Choosing the right sight is both a combination of researching reviews of Glock sights online, as well as personal preference. The number one thing on your mind when purchasing a sight should be durability and usability.
A note on durability. Simply put, they have to be reliable. They need to be made of steel, not plastic, and they need to have a durable aiming reference. Solid inserts are always preferable to paint or epoxy and they need to be available from a major manufacturer that offers a warranty. Don’t trust your life to the “Gun Show Special” you found on sale.
Expect to spend over $150 in most cases. The only two piece of the gun you actually interact with are the sights and the trigger. No other part of the gun requires your input to get a round on target. Take your sights seriously and you’ll be alright.
There’s no reason to have standard fiber-optic sights anymore. Unless your pistol is purely a bull’s-eye shooting pistol, fiber-optic sights are not anywhere near rugged enough. Most of the models are prone to the fibers breaking and the sights will be virtually useless in short order.
If you just, have to have a fiber-optic sight, look for products and companies like Hi-Viz which use a fiber-optic plastic that is much more durable than others. Make absolutely sure you check your front sight often for signs of wear and tear.
Some sights are designed for close in shooting very quickly, XS big dots are a perfect example. A shallow “V” shape in the rear, and a large white dot in the front. With practice, you can shoot these sights at man’s size targets out to hundred yards on a standard pistol like a Glock 19. However, they are very much a love it or hate it a fair.
Other, legendary sights like Meprolight or Trijicon HD’s are what most people would recommend for a first-time shooter. Their squared off front and rear sight match up well and their overall style lends itself well to fast, but precise shooting. Three dot varieties are almost always best for concealed carry guns.
Make sure if you plan on using a suppressor or a micro-red dot you buy suppressor height sights. They’re taller so you can still use them when your red dot right or suppressor is installed. Also, make sure your holster will work with your new sights. Standard sights you’ll rarely have a problem, suppressor sights you certainly will.
3. Installing Your Sight
Generally speaking, you’re going to want to have a competent gunsmith or armor and stall your sights. Not only is this process easy to mess up but pistol sights especially Glock sights are notoriously difficult to sight in. It would be all too easy for you to go out and buy expensive set of tritium night sights, only to break them trying to cite the minute the range.
Here is a general overview of what goes into changing a pair of Glock sights and what you should expect a competent gunsmith to do. This is a method that works without a sight pusher tool, which you most likely won’t have unless you’re a gun smith, it’s expensive and highly specialized tool.
Important note: Don’t apply thread locker or proofing marks before you take the gun to the range and make sure it’s sighted in. You can stake the rear sight after zero is confirmed but it’s not required.
- First safety check, field strip and disassemble the slide.
- Secure the disassembled slide in a vise right side up.
- Mark the placement of the rear sight within its sight channel.
- Using an appropriately sized nylon punch, drift out the rear sight left to right with light taps.
- You shouldn’t be straining to get it out, light taps with a gun-smith’s hammer should remove the rear sight.
- Clean the rear sight channel with a degreaser and wait for it to dry.
- Take your new rear sight and then drift it into the marks you left before you removed the old sight.
- Flip your slide over and secure it in a vise.
- Using a 3/16” fixed socket front, unscrew the bolt that holds the front sight to the slide.
- Save the bolt, your new sight may or may not come with a new one.
- Clean and degrease the hole and nut.
- Apply a VERY small dot of thread locker to the nut and screw the new front sight on.
- Use a torque wrench to the manufacturer’s specifications.
- Alternatively, screw it in until snug and then screw in another ¼ turn. *Don’t over tighten!
- Wipe away excess.
- Flip your slide secure in the vise.
- Look through the rear sight and ensure the front sight is centered in the notch of the rear sight.
- Make sure to do this before you allow the thread locker to cure.
- Allow at least 24 hours for the thread locker to cure before taking your assembled pistol to the range.

- Quick and accurate u-notch design
- Angled rear sight edge for emergency one-hand...
- Provides ultimate reliability, accuracy, and...
Designed to fit a wide variety of different Glock models the TruGlo Bright sights are awesome daylight and low light sights. The TruGlo sights use fiber optic material that is very easy to see throughout the day.
The green fiber optic material catches the eye and allows you to rapidly get on target. In the middle of a gunfight getting your front sight on target is critical, and the faster you do the faster you can shoot. The faster you shoot, the faster you can put a target down and retreat to safety. TruGlo bright sights are designed for rapid and accurate shooting. Outside of a combat situation these sights are perfect for competitions like ISPC, 3 Gun, and USPSA.
With time and accuracy being the goal in these competitions these sights are perfect for cutting split times. The sights themselves are very easy to install and anyone with any moderate technical skill can do it at home. The TruGlo Bright Sights use a very bright green fiber optic material in both the front and rear sights. This material naturally shows up well in low and daylight conditions. These sights alternate tasks and work as both day and night sights.
In low to no light situations the sight glows green. This makes them easy to pick up regardless of where, or when you are. The wielder of the weapon only sees the glowing nature of the sights. Anyone on the business end or to the left or right of the weapon cannot see the glowing sights. For the concealed carrier they make an all-around great set of sights. Their versatility is their key to success. They are also rounded and all corners have been trimmed to reduce snag.
This makes drawing from concealment simple and easy to do. It reduces the risk of the gun being snagged on clothing, which could prevent or delay a draw stroke. Although the sights have a rounded profile they can still be used against a belt to cock a weapon one handed.
The TruGlo sights are made entirely from steel, minus the fiber optics. This makes them stronger and more dependable than stock Glock sights.
2. Ameriglo ProGlo:

- Designed for simple front sight acquisition while...
- Front Outline Color: Orange
The Ameriglo ProGlo utilizes a simple, affordable, and effective sight system. The Ameriglo ProGlo sights are night and day sights that combine tritium and fiber optics for a bright sight picture for any shooting encounter.
To reduce the overall cost of the sights the front sight is the only one that is illuminated. The rear sight is almost entirely blacked out except for a small line of green material in the middle of the rear sight. This is directly below the cut in the rear sight.
In the daylight the shooter aligns the rear green line with the green fiber optic front sight for quick shooting. For longer range, more precise shooting, the shooter will align the front sight between the rear sights in a traditional manner.
Night shooting is a little different with these sights due to the single front night sight.
The idea is that as a shooter you focus so much on the front sight the rear sight doesn’t need to glow. Because the rear sight is blacked out in the middle of the night if you can’t see your front sight your sights aren’t aligned anyway.
If you can see your front sight at night on your target you are likely aligned or close enough to hit your target. The entire focus is on the shooting theory of front sight press. Get the weapon up, front sight on the target and pull the trigger.
Any shooting done at night is bound to be done at close range with a pistol, so precision comes second after speed in a defensive situation. When shooting for center mass hitting to the left and right of the front sight isn’t a major concern because you are still hitting center mass.
The Ameriglo ProGlo sights for the Glock 19 are quite versatile for both day and night shooting. In low light situations you’ll use the center green tritium lamp to shoot. During the day a bright green fiber optic material surrounds the center of the target.
Construction of the sights is impressive. They are made from bar stock steel and use Swiss made tritium lamps. This makes them quite tough and very rugged, way better built than stock Glock sights.

The front sight dots the vertical rear tritium lamp.If the i is dotted the rear sights are then aligned. The XS Big dots are extremely easy to use, and placing the front sight on target is quick and easy to do. This sight is designed to reduce the time used to find the front sight and put it on target.
