Tritium night sights

Tritium is the technology behind XS Night Sights, delivering a self-illuminating aiming reference that enhances visibility in any lighting condition. Learn how tritium works, why it's trusted by defensive shooters, and what makes it the preferred choice for long-lasting performance, durability, and low-light confidence.

Tritium is a beta-emitting radioactive isotope of hydrogen with a chemical symbol of H-3. The half-life of tritium is 12 years.

Most defensive shootings do not happen in complete darkness, nor do they take place in perfect lighting. They take place in between this broad-spectrum, making tritium the best self-illuminating light source for low-illuminating iron sights.

Our tritium sights glow in low-light situations, use high-contrast glow dots to provide high visibility in bright light, and are extremely durable. Our sights glow for over 10-years, have a 25K+ round service life, are drop safe, and can survive aggressive cleaning agents that contain Acetone. Built to meet strict tritium safety requirements, these sights deliver dependable performance for years of hard use.

XS Sights' patent-pending Glow Dot Technology absorbs ambient light and stores energy to create a bright, high-contrast front sight. Available in green, yellow, or orange, Glow Dots enhance visibility in bright light and continue to glow after light exposure, working alongside tritium for improved sight acquisition in changing light conditions.

Orange

Orange offers the best contrast in bright light conditions, such as daylight. It also boasts a very bright color in low/no light.

Orange

Yellow

Yellow

Green

As responsible gun owners, WE are accountable for every bullet that leaves the chamber of our gun. We want and need the bullet to go where intended. The ability to see your sights is key to shot accuracy. Unfortunately, this task becomes much more difficult when you're under stress. The adrenaline effects of fight or flight sets in, and tunnel vision focuses you on your aggressor. Keep in mind, it’s likely both parties are moving. You need to make some crucial decisions on what to do next and do it in under 3 seconds. (FBI Rules of 3). Keeping the effects of fight or flight in-mind, it is critical to have a good, visible set of iron sights installed on your defensive pistol. Self-illuminated tritium night sights provide glowing index points in low light to enable proper sight alignment. When it comes to tritium night sights, brightness counts, especially in the front sight. XS Sights R3D, DXT2, and F8 Tritium Night Sights all use brighter tritium lamps in the front than the rear.

Tritium sights have a half-life of around 12 years, which means that after this time, the brightness of the sight will have decreased by half.

Tritium sights have distinct advantages over Fiber Optic sights for a number of reasons. First and foremost, Tritium sights are designed to provide a clear and reliable sight picture in low-light conditions. Unlike Fiber Optic sights, which require ample light to function effectively, Tritium sights use a radioactive gas that emits a glow, allowing shooters to easily see and aim at their target in any lighting situation. Tritium sights are also highly durable and long-lasting. Unlike Fiber Optic sights, which can be fragile and susceptible to damage, Tritium sights are constructed with sturdy materials that can withstand the rigors of regular use and exposure to the elements. Another advantage of Tritium sights is their ease of use and reliability. It’s glow dot provides a clear aiming point which allows for quick and accurate target acquisition, even in high-stress situations. While both Tritium and Fiber Optic sights have their advantages, we at XS Sights believe that Tritium sights are the superior option for shooters looking for a self defense upgrade.

There are several advantages that Night Sights have over Red Dots: XS Night Sights utilize a combination of a photoluminescent dot and tritium to produce a glowing effect, enabling shooters to acquire targets quickly and accurately in any lighting situation. Red Dot Sights, on the other hand, require a power source or battery to function. Night Sights are also highly durable and long-lasting, being designed to withstand regular use and exposure to the elements, while Red Dot Sights are often more delicate and can be susceptible to damage from impact or weather conditions. Another advantage of Night Sights is their simplicity. Night Sights do not require complex adjustments or calibration, providing an intuitive aiming experience straight out of the box. This allows shooters to focus on their target without worrying about adjusting the sight. Night Sights are also a more affordable option compared to Red Dot Sights. All in all, Night Sights provide reliable performance and accuracy at an affordable price, making them an attractive choice for many shooters.

RMR stands for "Ruggedized Miniature Reflex" and refers to a type of red dot sight designed and manufactured by Trijicon®. The RMR sight is a compact and lightweight reflex sight that is intended for use on pistols, rifles, and shotguns.
