Tritium vs Trijicon: What is the Difference?

When it comes to firearms, one of the most important decisions a shooter can make is choosing the right sight. A good sight can make all the difference in accuracy, speed, and overall performance. Two popular options on the market are tritium sights and Trijicon sights. While both are designed to improve accuracy, they have distinct differences that shooters should consider. In this article, I will explain and contrast tritium vs Trijicon sights to help understand the differences. 

What are Tritium Sights?

Tritium sights, also known as night sights, are designed to be visible in low-light conditions. They use a small amount of radioactive tritium gas to create a glow that is visible in the dark.

The glow is produced by a process called phosphorescence, which is the emission of light by a substance after it has absorbed energy.

How Do Tritium Sights Work?

Tritium sights use a small glass vial that contains the tritium gas. The vial is coated with a phosphorescent material that emits light when the tritium gas interacts with it.

When the sight is exposed to light, the phosphorescent material absorbs energy, which is then released as a glow in low-light conditions.

Pros and Cons of Tritium Sights



Visible in low-light conditions

Less precise than fiber optic or iron sights

No batteries required

Not visible in bright light conditions

Long lifespan (up to 12 years)

What are Trijicon Sights?

Trijicon sights are a type of firearm sight that is designed to provide a clear sight picture in any lighting condition. They are often used by military and law enforcement personnel, as well as by civilian shooters who require a high level of accuracy and precision.

Trijicon sights use a combination of fiber optics and tritium to create a bright, glowing sight picture that is easy to see in low-light conditions.

How Do Trijicon Sights Work?

The fiber optic material collects and directs available light to the sight, while the tritium provides a self-luminous glow that remains visible even in complete darkness.

This combination of materials allows Trijicon sights to be highly visible and accurate in a wide range of lighting conditions.

Durable and reliable

Comparing Tritium vs Trijicon Sights


When it comes to accuracy, Trijicon sights are generally more precise than tritium sights. The fiber optics in Trijicon sights gather more light than the phosphorescent material in tritium sights, which means that the sight picture is clearer and more defined. This can make a big difference in accuracy, especially at shooting longer distances.


In low-light conditions, both tritium and Trijicon sights are designed to be visible. However, tritium sights are not visible in bright light conditions, while Trijicon sights are. This means that Trijicon sights can be used in a wider range of lighting conditions than tritium sights.


Both tritium and Trijicon sights are designed to be durable and reliable. However, Trijicon sights are generally considered to be more durable than tritium sights. This is because Trijicon sights are made from high-quality materials and are designed to withstand a lot of wear and tear.

Tritium sights are also durable, but they may require more frequent replacement due to the nature of the radioactive material used to produce the glow.

Battery Life

Tritium sights do not require batteries, which makes them low-maintenance and reliable. Trijicon sights, on the other hand, may require batteries for some models. This means that shooters need to keep spare batteries on hand and replace them regularly to ensure that the sight is always functioning properly.


When it comes to price, tritium sights are generally less expensive than Trijicon sights. However, the price difference can vary depending on the brand, model, and features of the sight.


Are tritium sights dangerous?

Tritium sights contain a small amount of radioactive material, but they are not dangerous to shooters or bystanders. The amount of radiation emitted by tritium sights is minimal and poses no significant risk to human health.

How long do Trijicon sights last?

Trijicon sights are designed to be durable and long-lasting. The tritium used in the sights has a half-life of around 12 years, which means that the glow will gradually diminish over time. However, the sight will still function properly even as the glow diminishes.

Are Trijicon sights worth the price?

Trijicon sights are more expensive than some other types of sights, but they are also considered to be some of the best on the market. If you prioritize accuracy, versatility, and reliability, the price may be worth it for you.

Choosing the Right Sight for You

When it comes to choosing between tritium and Trijicon sights, it ultimately comes down to personal preference and individual needs. If you frequently shoot in low-light conditions and prioritize affordability, tritium sights may be the right choice for you.

However, if you require a more precise and versatile sight that is reliable in any lighting condition, Trijicon sights may be the better option.
