Tritium sights basically provide green or yellow sight lights on your shotgun that glow in the dark. They have been nicknamed “night sights” for this reason and get installed on the rear or front of your shotgun. Tritium is described as a radioactive isotope of hydrogen. The sights use tiny vials of tritium that are responsible for emitting its soft green glow. If you are in an area with low lighting or darkness then the tritium sights will allow you to see where you’re aiming.

Tritium Sights on Shotguns

That way you don’t have to guess where you’re pointing your weapon. Many people make this mistake when they are hunting at dusk or at nighttime with their shotgun. After the sun starts to go down, they end up shooting their hunting partner because they can’t see the direction where they are pointing the weapon. These sights also come in handy when using shotgun for home defense. You can aim your shotgun before switching on flashlight.

Tritium shotgun sights are machine made with a steel exterior, which gives it the ability to withstand tough weather and other conditions. There is also a white ring on the front that allows using sights in daylight.

As for the diameter of the Tritium element, there are different sizes available to accommodate your shotgun and your specific needs for aiming. Some people like big green Tritium dot while others prefer the smaller dots.

Tritium sights that are waterproof and give you the ability to aim with both eyes open. They don’t even need batteries to work and they will glow for 12 years. Best of all, these sights cost on average of $30 to $40. This makes them truly affordable for any shotgun user.

One thing you don’t have to worry about is having your target see the light because the green lighting will only be facing you as you take aim. This is not a light that shines outward for your target to see like laser sights. Tritium sights allow you to aim discretely as a result. Just make sure you know where your target is because the sights won’t let you see your target in the dark. It will just let you see your weapon and the direction you are aiming it.

    I have installed this site on my home defense model. Nice sight, but not as bright as I thought. I ‘ll probably add the mount from Elzetta. Otherwisw product is as claimed. The triium is nice on the ol’ workhorse house gun.

  2. Excellent read Vitaly. I have spoken to the rep at XS Sights to help me figure out how exactly to do this upgrade to my model 870 Express Tactical Magpul shotgun. As soon as I have some time I will do this. Your articles are always well written and are enjoyable to read. Thank you for your experience.

  3. What is available for a barrel which has been cut back with no front sight whatsoever? Thin width base as it has been ported.

    Excellent idea was looking to get a different barrel with better sights since mine is just a bead this might help my tired old eyes . Thanks vitally for this info

    How does one remove it (in 12 years or so) when it’s time?

    1. You will need to find the way to remove epoxy. Haven’t done that before, so cannot give you advice.
