XS DXT II Big Dot Night for Glock 42, 43, 43X, 48 Green/Yellow Outline Tritium Handgun Sight Review

First Thoughts on the XS DXT II Big Dot Night for Glock 42, 43, 43X, 48 Green/Yellow Outline Tritium Handgun Sight

The XS DXT II Big Dot Night Sight is a sight system designed to enhance quick target acquisition, especially in low-light conditions, for popular compact Glocks. Specifically, it caters to the Glock 42, 43, 43X, and 48 models. The XS Sights company promises a significant upgrade over factory sights, emphasizing speed and visibility in defensive scenarios.

I’ve always been a proponent of carrying compact Glocks for concealed carry. However, the factory sights, while functional, often leave something to be desired when speed and low-light performance are paramount. The search for a sighting solution that prioritizes rapid target acquisition and reliable performance under stress led me to consider the XS DXT II Big Dot Night Sight.

Unboxing the XS DXT II, the first thing that struck me was the sheer size of the front sight. The Big Dot is, as the name suggests, substantial, and the contrasting green/yellow outline around the tritium vial immediately drew my eye. The rear sight, with its shallow V-notch and vertical tritium stripe, appeared equally well-made and designed to complement the front. The CNC machined steel construction gave a sense of durability.

I considered several other night sight options, including those from Trijicon and Ameriglo. However, the XS DXT II‘s emphasis on simple, intuitive target acquisition with its large, high-visibility front sight and minimalist rear won me over. I was also looking for a system that minimized the potential for overthinking in a high-stress situation. My initial excitement stemmed from the promise of faster target acquisition and improved accuracy under less-than-ideal lighting.

Real-World Testing: Putting XS DXT II Big Dot Night for Glock 42, 43, 43X, 48 Green/Yellow Outline Tritium Handgun Sight to the Test

First Use Experience

My first experience with the XS DXT II was at an indoor shooting range. I was focusing on close-quarters defensive drills. The range offered varied lighting conditions, simulating both daylight and low-light scenarios.

The Big Dot front sight was incredibly easy to pick up, even in the dimmest lighting. The intuitive “dot-the-i” sight picture significantly reduced the time it took to acquire a proper sight alignment and get on target. In a high-stress simulated scenario, the sights instilled confidence in my ability to react swiftly and accurately. There were no immediate issues to report, and I felt far more confident with target aquisition.

Extended Use & Reliability

After several months of carrying and using the Glock 43X equipped with the XS DXT II, the sights have held up remarkably well. There’s no noticeable wear and tear on either the front or rear sight, despite consistent daily carry.

Maintenance is simple. Regular cleaning with a soft cloth is all that’s been required to keep the sights functioning perfectly. Compared to previous experiences with more complex sight systems, the XS DXT II offers a simpler and more reliable aiming solution.

Specifications

The XS DXT II Big Dot Night Sight is a front and rear sight set, CNC machined from steel for durability and finished in black. It’s specifically designed for the Glock 42, 43, 43X, and 48 models. The system utilizes a large, high-visibility front sight with a tritium insert surrounded by a green or yellow Glow Dot. The rear sight features a shallow V-notch with a vertical tritium stripe.

The use of CNC machined steel ensures the sights are robust and resistant to wear and tear. The tritium inserts provide constant illumination in low-light conditions. The Big Dot design facilitates rapid target acquisition.

Performance & Functionality

The XS DXT II excels at its primary task: rapid target acquisition in all lighting conditions. The large front sight is exceptionally easy to see and quickly align with the target. Accuracy at typical self-defense distances (3-15 yards) is excellent.

The simplicity of the sight picture minimizes the potential for confusion or hesitation in a stressful situation. The dot-the-i configuration is intuitive and easy to learn. The only potential drawback is that the Big Dot may obscure smaller targets at longer distances, but this is a trade-off for its speed and visibility at close range.

Design & Ergonomics

The build quality of the XS DXT II is top-notch. The CNC machined steel construction feels solid and durable. The design is minimalistic and functional, prioritizing speed and visibility over aesthetics.

The sights are relatively low-profile, minimizing any increase in overall handgun size. Installation is straightforward for anyone familiar with Glock sight replacement. The Big Dot may take some getting used to for those accustomed to traditional three-dot sights, but the learning curve is minimal.

Durability & Maintenance

The XS DXT II is built to last. The steel construction and durable finish provide excellent resistance to wear and corrosion. Maintenance is minimal, requiring only occasional cleaning to remove dirt and debris. The tritium inserts are rated for several years of continuous illumination, ensuring long-term reliability.

Accessories and Customization Options

The XS DXT II is primarily a standalone sighting system and doesn’t require any additional accessories for its core functionality. While the front sight is available in either green or yellow, the system is designed as a complete unit.

There are no readily available options for swapping out the front or rear sights with aftermarket components. The sight fits tightly and securely once installed.
