The TRUGLO TFO is a tritium and fiber optic combination handgun sight for Glock pistols. These claim to have unmatched visibility in all shooting conditions, and since it combines both sight styles, works both in daylight, low light, and no light situations. The TRUGLO features a green tritium dot and green optic fiber in the front sight and offers a choice of green or yellow for the rear sight for increased contrast and fast target acquisition.

Other features of this sight are a tough Fortress Finish coating for increased protection, concealed grooves that hide the fiber optic so it won’t be seen by your target, and a snag-resistant design that will fit standard holsters. It claims to be machined and assembled in the USA and carries a 12-year limited warranty.

Customers love this sight and are big fans of the beautiful design and ease of installation. Most agree that the color combination and arrangement of the tritium and fiber optics together guide your view directly to the front of the sight where it should be.

Consistent complaints about this product are that the front sights wear out fairly quickly; within about one year or 100 rounds. Others reported that the front sight only lasted about three months.

They have that wonderful green and white color scheme with the super bright shining tritium green dots and a bright white ring around the outside on each sight post for easy daytime alignment.

Customers of these sights praise a quick, easy install and love how well they are made. Many people are reporting these to be of the same quality as pricier Trijicons.

  • Metal OEM Green Dot Night Sight Set
  • 6.1mm slim rear
  • Front sight with screw
  • Green tritium ampules set in a white contrasting background

The Glock 43 42 Factory OEM Night Sight is a simple but powerful set. It may not be as fancy as some of the combination sights, but it’s equipped with a bright quick contrast green tritium night dot that turns bright white in the light for quick focus even in the daytime. These are a true Glock product with their logo stamped into the metal and finished with the same gas coating as the Glock slide. It is the perfect complimentary attachment for your Glock.

Customers of these sights are fans of the nice low profile and the night sight color contrast that is bright enough, but not so much that they would stand out to an intruder that may be ten or more feet from you.

On the flip side, those same bright but not glaring glow are too dull for some people who do want a more radiant light. Also, the white area around the green dots is hard for some people to see at all in a dusk time of day.

    • Tritium green night dots turn to white during daylight hours for easy daytime focus
    • the sight has the same finished treatment as the rest of your gun and is tough

As with all other tritium made products, no batteries or re-charging necessary.

These are manufactured of tough CNC machined steel, that is both machined and assembled in the USA. Then, it is finished with a Fortress Finish coating for maximum protection. Ultimately, one of my favorite features is the snag resistant design with its rounded outside edges. As with other TRUGLO products, these come with a 12-year limited warranty.

Customers of these night sights report that they are super bright, even brighter than their more expensive competitors. Others love how easy they are to install and that they are not too fancy. The white dots they turn into during daylight hours are more than sufficient for a good line up.

Again, the main customer complaint of this product is that the front sight tends to wear out very soon, within the first 100 rounds or so.

  • What Are Night Sights?

    Night sights are a luminescent replacement for factory irons or white dot sights. They are very useful for aiming in low light conditions as they emit a soft glow to line up on target.

    There are mainly two different types of night sight to choose from. The first is a Tritium sight. Tritium is a radioactive isotope that creates its own light. This type works on independently and will glow in complete darkness. During the day it sort of just looks like a washed out white dot.

    The second type is a fiber optic sight. Fiber optics are thin glass fibers that gather existing ambient light and reflect it outward. They are very visible and brightly colored during the daylight or low light conditions, but don’t work in complete darkness. They are usually more linear than just dots like the tritium sights.

    These are the main two types, however, there is also a combination type sight that combines the tritium and the fiber optics for use together. Just as a side note, you can also get sights that are neither of these, but simply a type of phosphorescent glow in the dark paint that must recharge from direct light every eight hours or so.

    Night sights can be chosen in a variety of colors, red, orange, yellow, green or a combination of two. Dual colors can really make your sights stand out more. For the most part, you would want a nice color contrast with your brightest color forward, at the end of the barrel. It is generally concluded that the green is the brightest of these, so that would be what you’d want up front.

    Lifespan Of Night Sights

    Nothing lasts forever and the same is true for your night sights. Tritium based sights have a half-life of twelve years, so every twelve years their brightness is cut by half. It’s a gradual dimming, but you would probably want to replace them once they reach that point as they are not rechargeable.

    Fiber optics’ glow source will last indefinitely, as it is just a glass or plastic rod that takes in existing ambient light and reflects it back out. The lifespan on this sight then is determined by the actual fiber itself wearing out. These do need to be replaced between every thousand rounds or so. They get broken, loose, cracked or scratched fairly easily.

    Benefits Of Installing Night Sights

    Most feel that the benefits of night sights vastly out-weight the drawbacks. The biggest benefit is the obvious one, it assists your aim in low light or no light conditions. Having that little bit of glow is great for focusing and lining up your target in the dark. Believe it or not, they also really assist in target re-acquisition after being blinded by muzzle flash.

    Most people agree that night sights are much better made than the factory white dot sights that come pre-installed on your firearm. At least they are metal with the glowing goodies. The factory sights are plastic and usually have an inferior dot system painted on them.

    Another benefit is that you can pick your own colors. On standard factory set sights, the only choice you get is what comes on the gun, the white dot sights or solid black irons. Bright colors can help you to focus your aim better. And, all dots don’t have to be the same color. It’s very common to choose the brightest green for the front sight and bright contrasting color like orange for the rear sights. This way, especially in darker conditions, all lights don’t fade together and you can get a proper alignment.

    It’s easier to find your firearm in the dark with the night sights since they emit that constant glow. It really sucks to be fumbling around for your firearm in the dark when you wake up suddenly to the sound of the back door getting kicked in.

    Low Light Conditions

    This is the main reason for equipping night sights and makes for a huge difference if you’re in a situation to defend your home. Being able to see the exact direction you’re shooting quickly is very important.

    While it’s not going to light up the target you’re aiming for you have to experience using Glock night sights to really grasp how effective they can be.

    Works During Daylight Hours

    With the misconception, night sights are less effective during the day or that they don’t work at all we had to put this one here.

    During daylight hours your night sights will function as enhanced normal sights. I say enhanced because even during the day they’re an improvement over the standard sights that come with your Glock.

    Quality Sights

    With night sights being extremely popular they’re being made in high-quality materials that are often better than the default. As long as your sights are coming from a reputable manufacturer it’s very likely to be a complete upgrade across the board.


    Not everyone does well or likes the standard night sight color. The good news is these night sights can be found in a wide range of colors from yellow, white, orange, etc..

    Drawbacks to Using These Sights

    Drawbacks to night sights are few and far between. Fiber optics are rather fragile and the filament needs to be replaced about every thousand rounds or so, but the rods are inexpensive.

    Also, you can see the glow of the tritium sights through clothing, depending on the clothing, and that may not be desirable. Finally, night sights are overall less budget-friendly than regular irons, but most people will attest that they are well worth it.


    While there aren’t really any negatives for night sights the one thing that does stand out is the price of them. These sights can be expensive and not all sights are going to fit into everyone’s budget.

Commonly Asked Questions

What is Tritium? – Tritium is a radioactive isotope of hydrogen. When used in night sights, it is contained in a little glass lamp that usually has some sort of a phosphorescent coating. Tritium emits it’s own light and will glow in low light or no light conditions without the use of batteries or any type of charging involved.

How long will Tritium last? – Tritium has a half-life of twelve years, so every twelve years it is only half as dim as before.

How do fiber optics work? – Fiber optics are thin glass or plastic fibers that catch existing ambient light and reflect it back outward. These also have no need for batteries or recharging, however, they cannot work in complete darkness conditions.

Are fiber optics night sights? – Yes, to some extent. Fiber optics require an existing light source in order to work because they capture that light and reflect it back out. They are no good in blackout conditions but work wonderfully when paired with tritium dots as total darkness back up. They help to give contrast and focus during daylight or low light scenarios.
