2 Glock 43 – Factory Night Sight Set – Best OEM Glock 43 Sight
Many Glock owners will be surprised that Glock actually makes some really good pistol sights. It is just that they put standard sights on their range of handguns! To up your target acquisition speeds and accuracy, here is an OEM model from Glock themselves.
Straightforward quality design!
The rugged build of this quality sight means it should see you through many years of use. Because the height and design of conventional Glock sights remains the same, it is ultra-easy to install on your Glock 43; in fact, it is probably the easiest to install Glock 43 sight that you can buy.
This is a straightforward screw-in type of front sight that sits very securely on your pistol. Once installed, you will find the front sight and the 6.5 mm high rear sights work in tandem. This will help you quickly acquire targets and shoot with accuracy.
3-Dot aiming system…
It achieves sight acquisition through the use of a 3-Dot aiming system; 2 rear and 1 front illumination points. You can then add to this a contrasting white ring. The end result is that during daylight hours, you benefit from the white glow; at night, the tritium green glow.
- Rugged build.
- Glock OEM quality.

3 XS SIGHTS DXT2 Big Dot Night Sight for Glock Pistols – Most Durable Glock 43 Sight
XS Sights have been in the night optic business for over 20 years. This DXT2 Big Dot night sight is the second generation of a design that has proved popular.
Front and Rear self-illumination
CNC machined from steel bar stock and then blued for rust resistance, this Texas-built scope is as robust as they come. The design allows it to fit in the majority of Glock 43 compatible holsters. There will be no concealed draw hindrance as this quality sight has no sharp edges on which to snag.
The sight comes with self-illuminating tritium vials in both the front and rear sight. It is also equipped with phot luminescent Glow Dot technology. In bright light, this offers a high-contrast sight picture, it absorbs ambient light and also glows in low light.
Because of the way these two glowing features are paired, it gives you a significant tactical advantage. During any low-light encounters, the front sight is more visible and glows brighter than the rear sight.
There is a reason these are termed ‘Big Dots.’ They measure in at 0.188-inches which makes them the biggest Glock 43 front sight currently available. Regardless of having to shoot in daylight or low light, it is the increased surface area that makes the dot brighter. This not only speeds up front sight acquisition, but it is also effective if your eyesight is not as good as it used to be.
While on the topic of eyesight, shooters can choose between yellow or orange color options. The yellow choice glows the strongest while orange contrasts when shooting in bright light. The in-line sight picture of either color allows natural sight alignment while also increasing your down-range field of view. On top of this, the reduced number of alignment points helps reduce eye stress.
Simple to install…
Installation is quick and easy thanks to the included front sight install tool. It fits the front sight screw perfectly, meaning there is no need for other tools. To install, simply unscrew the original Glock front sight, add a dab of the included red threadlocker, and tighten.
- Gen 2 version.
- Very solid build – Long guarantee.
- Big dot helps clarity of target view.
- Ease of install.
- Some negative comments re. accurate target alignment.

Best Glock 43 Sights Buyers Guide
Glock 43 owners already know how easy their weapon is to conceal carry and how effective this single-stack handgun can be. The one improvement that many comment on relates to the factory-installed sights and how these could be improved. The simple answer is to install one of the many aftermarket sight models available for this popular weapon.
So, here are five pointers that will help speed up your research and land you a Glock 43 sight to fit your shooting style.
You Need a Robust, Durable Build
It is a fact that many Glock 43 owners do not leave home without their trusted handgun. This is because they are very easily concealed and, with the right holster, comfortable to carry.
While this is an obvious plus, it does mean constant wear and tear on accessories such as an aftermarket sight. With that in mind, it is essential you choose a sight for your Glock 43 that is built to last. One that will perform to the highest level when required.
Quality CNC-machined steel sights are an excellent choice, and some designs are as tough as your handgun. It also pays to look at such sights that have been built to the same OEM specs as your Glock 43 handgun. This makes for easier installation, a firmer fit, and a clear, fast sight acquisition.
Dot – Day / Night Use
Manufacturers offer these sights with a variety of dot colors. But before deciding on illumination color, take these considerations into account:
When are you out and about on business and pleasure? Only during the day? Mostly at night? Or, as most will find, a mixture of both? By the very nature of your movements, it is likely there will be times you are out in daylight, low-light, and even complete darkness.
What is most important is to choose the sight that best suits your activity. In reality, for the vast majority of Glock 43 carriers, it makes absolute sense to have a sight that offers both a daytime and a nighttime operation mode. Because we all know that emergency situations do not just happen after nightfall, this will surely help reduce any anxiety.
You then Need to Decide on Which Sighting System Suits Your Shooting Style Best
The options are generally between a more traditional 3-dot sight or a quick focus 1-dot sight.
There is no right or wrong to the shooting style you adopt or the tritium illumination color chosen. In both instances, it should really be what you feel most comfortable with.
To give a few color examples, orange dot sights tend to be slightly brighter than other colors. This should mean they are easier to see during daylight. Green and orange are also popular for low-light and night use. In general, green illumination will last longer than other colors. Having said that, all quality Glock aftermarket sights will give you long years of use regardless of the color chosen.
Power is Not a Concern – But…
It is tritium that makes the dots of this type of sight glow. Many people are unnecessarily concerned about tritium because it is a radioactive form of hydrogen. However, because such small amounts of tritium are used for illumination, there really is no cause for concern. To prove this fact, many tests have been carried out, and no radioactivity has been found. Please rest assured that these sights are perfectly safe to use.
Tritium-style sights do not need batteries. You will never have to worry about them being dead when needed or worry about turning them on. Draw your weapon, and the tritium illumination springs into life.
Of course, over years of use, this illumination will fade, but that is certainly not a short term concern. Choosing a quality manufacturer means you can expect between 8 and 16 years of use. That is a long time when compared against the initial investment.
Correct install is Key!
The majority of the best high-quality Glock 43 sights available offer fairly easy self-install. However, if in doubt, do not try to fudge installation by saving a few dollars. Gunsmiths are there for a reason, and the once-off cost for sight install is certainly not excessive. Whatever install route you take, the key is to get the most out of your chosen sight.
A correctly installed best Glock aftermarket sight assists with aim. It also ensures a bright, crisp dot view is yours every time you draw and aim at a target. An incorrectly installed tritium sight may not give you maximum illumination. This tends not to be a problem with the actual sight build, rather a wrongly installed sight.
As with all firearms accessories, cost is an important factor. The thing to remember here is to balance the initial upfront cost against longevity of use. Purchasing one of the best quality Glock 43 sights should in no way be looked at as a short-term purchase. As already mentioned, quality manufacturers guarantee their sights for between 8 and 16 years.
Work the initial purchase cost out against projected years of use, and this type of sight becomes a bargain. To ensure peace of mind, it is also wise to check the warranty period of any sight you are considering. If a manufacturer stands behind their product, then a healthy warranty will be included in purchase.
