Best Night Sights for Glock

There are all kinds of sights available for handguns like the Glock 17, 19, 22, 26, 32, 37. However, out of all them, the tritium night sights are the most preferred amongst Glock owners. Why are they preferred? For one thing, the tritium can be seen in dimly lit environments and totally dark environments. You also don’t need a battery to power the lighting source because the tritium lighting doesn’t come from electricity, lasers, or bulbs. It is a radioactive isotope that comes from hydrogen which emits a soft bright glowing light. Since the tritium has radioactive decay that emits electrons, this causes the phosphor of the tritium to glow. It does not need any kind of outside power source whatsoever. The radioactive decay can last for several years which means it will glow for up to 10-12 years.

If you try using a tritium night sight during the day, you won’t be able to see the light emitted from it. Tritium can only be noticed in darker environments, which is why it’s marketed specifically as a night sight. Of course, if it is totally dark in your environment then you might have trouble seeing what you’re shooting at. So, the tritium night sight is best used in low lit environments where you can still somewhat see what is in front of you or combined with handgun flashlight. If there is a lot of moonlight outside, then you may have a better idea of what you’re shooting at.

Glock 17, 19, 22, 26, 32, 37 are mainly used for self-defense purposes, whether it is by an ordinary citizen or a police officer. In fact, more than 60% of American police officers carry a Glock. They can hold 15 and more rounds per magazine and can shoot as a semi-automatic weapon with very little recoil. Since police officers are usually engaging suspects in dark rooms of buildings or houses, it helps that they have tritium night sights attached to their Glocks. Most of them will shine a flashlight next to their Glock so they can positively identify the person in front of them. Then, if they pose a threat then the officer can aim accurately with the tritium night sight and take the suspect down.


The Trijicon HD XR Night Sights are available for multiple versions of the Glock. This particular advancement in night sight technology is made specifically for helping the shooter identify their target at long distances. Law enforcement officers are the ones who will truly benefit from this the most. They are used to dealing with suspects in dark environments or outside at nighttime. Now they’ll have an expanded field of view, so they can identify suspects first before shooting at them. This reduces the chances of them shooting the wrong person.

Trijicon- HD XR Night Sights for Glock

Trijicon’s HD Night Sights are hugely popular amongst Glock users. It only makes sense that Trijicon would expand on this line of night sights by putting new features into it. The result is the Trijicon HD XR which is more advanced at engaging targets that are farther away. The front sight of the HD XR is thinner as well. This allows users to have a bigger field of view.
Of course, the highlight of the Trijicon HD XR is its tritium-phosphor lamp. This is basically a glass lamp that is filled with tritium. This provides users with a bright illuminating light which you can see clearly in dimly lit and dark environments. Because it is tritium based, you won’t need to purchase any batteries or provide any additional power source to it. The tritium provides the illumination on its own.
The Trijicon HD XR is actually a set of night sights. There is the enhanced tritium sight on the front and there is the rear sight with a U-notch in it. This rear sight is what helps the user align their target with the front sight properly. Other features of the HD XR include a sapphire window, protective cylinders made of aluminum, steel shell with a matte finish, and a silicone rubber cushion. These materials give the night sight set added durability to withstand harsh weather conditions.
The color of the tritium lamps is green. The manufacturer has given them a 12-year warranty from the date they were first manufactured. This means they should be able to stay illuminated consistently for up to 12 years. Of course, you won’t be able to see this illumination if you’re outside during the day or in a bright interior environment.
The price of the Trijicon HD XR is around $149.00 on most websites. The width of the blade is 0.122” and the height of the blade is 0.23”. It was manufactured in the United States like all high-quality firearm accessories.
