Before we forget, the capsules contain Swiss tritium gas at the front and the fiber optic element at the rear. The two of them make sighting and light gathering

- Additional protection from shock and cleaning solvents
- Front sight is not snug

Though its front sight is not of green color, you can expect this Glock sight to function well in all lighting conditions.
XS Big Dot is highly recommended for self-defense or combat situations wherein you shoot your target at close ranges.
It is not expected and not designed for range shooting.
Being a self-defense night sight, the front dot must be big. Its function as a sight optimizes your speed and visibility. The white dot is easy to differentiate and has good contrast between the target and the background in any lighting condition.
The brightness of the single dot on the front sight is determined by the glow-in-the-dark paint and the tritium light. The paint is suitable for daytime use to enhance its visibility. Then, the rear sight of XS Big Dot features a shallow V-platform.
The way you look at the Glock sight fully installed, the front sight is a little detached from the rear forming an “i.”

Dotting the “i” is the proper sight alignment. This is especially true at close ranges (0 to 15 yards). However, at ranges over 25 yards, you should use the top of the big dot as your aiming point because it’s the point of impact.
Keep in mind that this Glock sight is not designed for long-distance shooting. It’s designed specifically for self-defense/tactical purposes. The wide gap between the front sight and rear sight makes the target acquisition fast and easy.

Glock Sights Buying Guide
Glock pistols are acknowledged to be proficient in conceal carry. From the frame of the Glock to its magazine body, they are all made of high-strength nylon polymer which increases durability.
It is also observed to be more resilient than other metal-framed guns. The polymer used is also resistant to shock and extreme temperature.
Because the Glock is mostly hard plastic, its accessories must also use the same material, or at least the weight of the accessory won’t wear the weight of the gun down.
The night sights for Glock have excellent compatibility and are quite a good deal to have. Night sights for Glock pistols are also good for daytime usage, but not as bright as you use them at night.
In any model, they should be able to focus properly as well as aligning the aim accurately. Choosing them requires you, as a buyer, to consider some factors. These factors are listed as follows:
Common night sights don’t need batteries as a power source. What makes them visible at night or in daylight is the composition inside the tubing.
For a first-timer buyer such as you, some night sights use tritium, a chemical identified as a radioactive isotope of hydrogen.
Its radioluminescence creates a fluorescent light with no need for electrical energy. Moreover, though it’s radioactive, it doesn’t pose any threat because the tritium gas is usually encapsulated in a non-hydrogen-permeable container.
A newer innovation has entered its way to the market. The use of fiber optic tubes insights was very beneficial to the users because the material glows brightly even in normal light.
Also, it has many colors to choose from. The glow coming from the fiber optic is concentrated and doesn’t magnify. This aids you to see your target clearly because it’s not too bright and doesn’t obscure the target in any way.
However, the use of fiber optics in night sights means that it won’t last very long due to its chemical composition. This is unlike the tritium sights in which they last at least a decade before fading.
The Glock sights are recommended to be made of metal such as steel or aluminum. They don’t add much weight to the pistol and can take quite a beating from the repetitive recoils.
The plastic housing is not recommended because it has chances of breaking at some point.
The best Glock sight is something that can be used even if it’s daytime or nighttime. Not all attacks must happen at night so better be prepared for worst-case scenarios. The night sight you should get must have fast target acquisition.
4. Front Sight
The front sight of a Glock sight is preferred to have a large dot so that your focus is towards the front and not at the rear. The profile of the front sight is typically in a semi-ramp style.
Here, the face of the sight is facing away from the shooter and the best choice is to reduce the snag profile.
Night sights come in varying widths for the front area. Depending on the width, it would affect the speed and accuracy of your Glock.
Of course, there are disadvantages if the front sight is too wide. It would pose problems when you acquire the target at longer distances.
5. Rear Sight
Commonly, the rear sight of most night sights for Glock features two dots located side by side. They can either be painted or tritium.
The rear sight helps you get the best possible shot because it gives off a softer glow to emphasize the front sight dot.
The profile design of most night sights are classified as follows:
three-dot sight – Most handgun sights have three dots on them, two at the rear and one at the front. These night sights can either have fiber optic or tritium inserts or a mixture of both.
Two-dot sight – This kind of setup features a smaller dot at the rear and a large dot at the front area. Of course, the front sight is brighter while the rear sight focuses more on giving a soft glow to emphasize the main dot.
I-dot sight –This type has a large dot on the front sight, and the rear sight has a line painted under the notch. When aiming, you have to dot the “I” which means that the center of your aim is the center of the dot.
U-shaped rear sight – This type is commonly used by shooters into target competitions. The setup makes it easy to aim at long distances.
