TruGlo TFO Square Low Set for Glock 42, 43 Tritium/Fiber Optic Handgun Sight Review

The TruGlo TFO Square Low Set for Glock 42, 43 Tritium/Fiber Optic Handgun Sight Made a Bold First Impression

After countless hours on the range and in the field, I’ve learned one thing: your sights are your lifeline. You need to be able to acquire your target quickly and accurately, regardless of the lighting conditions. That’s why I was intrigued by the TruGlo TFO Square Low Set for Glock 42, 43 Tritium/Fiber Optic Handgun Sight, a product promising exceptional visibility in any situation.

My aging eyes were having a harder time picking up the factory Glock sights, particularly in low-light scenarios. I needed an upgrade that provided a clear, crisp sight picture without sacrificing durability or a low profile. I considered other fiber optic options, as well as some night sights, but the TruGlo TFO seemed to offer the best of both worlds. The combination of tritium and fiber optics promised unparalleled visibility, and the TruGlo name is generally associated with quality.

Upon unboxing, the TruGlo TFO sights presented a robust, yet refined appearance. The square notch design was a welcome change from the standard U-notch, which I found less precise. The initial impression was one of quality and thoughtful design, with the tritium vials glowing faintly even in daylight, hinting at their nighttime brilliance.

Compared to standard Glock sights or even some aftermarket all-black sights, the TruGlo TFO immediately stood out. I had considered some Ameriglo options, but the TruGlo design, with the square notch and combined tritium/fiber optic, seemed more appealing for my needs. I passed on some cheaper, no-name fiber optic sights. The risk of them breaking or having dim fibers just wasn’t worth the minimal cost savings. My initial excitement was high; these sights looked like they could solve my visibility issues and improve my shooting.

Real-World Testing: Putting TruGlo TFO Square Low Set for Glock 42, 43 Tritium/Fiber Optic Handgun Sight to the Test

First Use Experience

I first tested the TruGlo TFO Square Low Set at an indoor range, simulating low-light conditions. The difference compared to the factory Glock sights was immediately noticeable. The bright fiber optic front sight practically jumped out, making target acquisition significantly faster. The square notch also provided a more precise sight picture, leading to tighter groupings at 7 yards.

I also used the sights during an outdoor range session on a cloudy day. The fiber optics, even without direct sunlight, gathered enough ambient light to provide excellent visibility. The sights performed flawlessly, even when the target was partially obscured by shadows. There were no issues during the first use. The sights were bright, easy to use, and significantly improved my shooting accuracy.

Extended Use & Reliability

After several months of use, the TruGlo TFO sights have held up remarkably well. They’ve endured hundreds of rounds downrange, and there are no signs of wear or fading. The Fortress finish has proven to be very durable, resisting scratches and dings.

Cleaning the sights is simple. A quick wipe with a cloth is all that’s needed to remove any powder residue. They’ve proven to be more reliable and easier to maintain than some cheaper sights I’ve used in the past. They outperform standard Glock sights, as well as any sights without tritium or fiber optic elements. The TruGlo TFO Square Low Set has become a trusted and indispensable part of my Glock 43.

Breaking Down the Features of TruGlo TFO Square Low Set for Glock 42, 43 Tritium/Fiber Optic Handgun Sight

Specifications

The TruGlo TFO Square Low Set for Glock 42, 43 Tritium/Fiber Optic Handgun Sight is designed specifically for the slim-frame Glock 42 and 43 pistols. The sights feature a square notch rear sight, a fiber optic front sight, and tritium inserts for enhanced visibility in all lighting conditions. They are constructed from steel with a Fortress finish for maximum durability. The low-profile design ensures they don’t snag on clothing or holsters.

These specifications are critical for several reasons. The steel construction and Fortress finish guarantee durability and resistance to corrosion, essential for a firearm component that will be exposed to the elements and constant use. The tritium and fiber optic combination provide exceptional visibility in both bright and low-light conditions. This ensures accurate target acquisition regardless of the environment. The low-profile design is important for concealed carry, preventing the sights from snagging on clothing during draw.

Performance & Functionality

The TruGlo TFO Square Low Set performs exceptionally well in its intended role. The combination of tritium and fiber optics provides a bright and clear sight picture in virtually any lighting condition. Accuracy is noticeably improved due to the enhanced visibility and the precise square notch design. Reliability has been flawless, with no issues encountered during extended use.

One weakness is that in extremely bright conditions, the fiber optic can sometimes wash out slightly, although the tritium still provides a visible aiming point. The overall performance far exceeds expectations, delivering a significant improvement over stock Glock sights.

Design & Ergonomics

The build quality of the TruGlo TFO Square Low Set is excellent. The sights are made from durable steel with a Fortress finish that is resistant to scratches and corrosion. The weight is minimal, adding little to the overall weight of the pistol. The sights are comfortable to use, with no sharp edges that could cause discomfort.

There is a minimal learning curve. Installing the sights requires a sight pusher tool or a gunsmith. Once installed, the sights are intuitive and easy to use, even for novice shooters.

Durability & Maintenance

The TruGlo TFO Square Low Set is built to last. The steel construction and Fortress finish provide excellent resistance to wear and tear. With proper care, these sights should last for many years.

Maintenance is simple. A quick wipe with a cloth is all that’s needed to remove powder residue or dirt. The tritium vials have a lifespan of approximately 12 years, after which they will gradually dim.

Accessories and Customization Options

The TruGlo TFO Square Low Set does not require any additional accessories for basic functionality. Some users might choose to add a weapon-mounted light to further enhance visibility in low-light conditions. There are no specific customization options for the sights themselves, but they are compatible with standard Glock holsters designed for use with aftermarket sights. Be sure to choose a holster that accommodates the sight height to ensure a proper fit.
