They are engineered to withstand almost all light settings. Brilliant Aiming & Accurate Solutions for shooting enthusiasts. Take use of this cutting-edge technology for dependable aiming solutions.

Key Feature

Great Sight Acquisition

Trijicon HD Night Sights are a collection of three luminous sights with a distinctive design. To aid sight acquisition, the front sight has a very apparent photoluminescent pattern.

The “U” notch rear sight is slanted and serrated to help with front-sight concentration and decrease brightness.

Larger Field of View

These Night Sights are built on the characteristics of the existing HD Night Sights by providing a thinner front-sight mount. This allows users to see a broader field of vision, improving their ability to recognize targets. It also ensures that they can hit targets at larger distances.

Unique Built-in Parts

For daylight vision, Bright & Tough Night Sights include a white ring around the lighting dots. In no light or low light situations, a tritium-filled glass bulb offers exceptional lighting.

Each Trijicon tritium light is topped with a sapphire gem. This helps to disperse light evenly. It also protects the bulb from chemicals and rupture.

Visibility Due to the Dots

Green, yellow, and orange targeting dots are featured on Trijicon Night Sights. The maximum level of visibility is provided by green dots. Rear sights with yellow and orange dots make it easier to distinguish between the front and rear sights.

Tritium Night Sights 

Tritium Night Sights

Tritium night sights are self-illuminating, using a small quantity of luminous tritium gas to create a bright dot visible in low light or darkness.

The tritium light source will endure for many years. It doesn’t need to be changed frequently.  Fiber optic sights, on the other hand, are designed to be used in daylight.

Standard tritium sights have a basic, long-lasting design that emphasizes the tritium lamp’s ability to shine in the dark as much as possible.

Keeping one end of the lamp face as near to the sight face as feasible results in greater light intensity. 

Photoluminescent Night Sights

Photoluminescent Night Sights

There is nearly always some light present in defensive shooting scenarios, and most do not take place in full darkness. They occur in the middle of the light spectrum, between bright and dark.

Photoluminescent night sights absorb all ambient light and provide a more apparent, lighted front sight. When used in conjunction with tritium, the lamp’s light will somewhat charge the dot.

The dot will be lit in some way even in complete darkness. This combination guarantees that the front sight always shines brighter than the back, preventing confusion when firing under pressure. 

Sig P320 Fiber Optic Sights

Fiber Optic Sights

One of the most helpful improvements you can make to your weapon is adding a sight. In a variety of ways, sights improve your accuracy and shooting range. Fiber-optic sights do this by utilizing a clear and flexible optical fiber.

The fiber is typically constructed of tiny plastic or glass threads about the size of a human hair strand.

Fiber-optic sights are a fantastic choice for a handgun or pistols since they can transfer light along their fibers. They are highly reflective and ideal for low-light conditions.

Ambient light is taken up along the threads, which makes it easy to see with fiber-optics.
