SIG SAUER X-Ray3 Pistol Sight Set, No. 6 Green Front, No. 8 Rear, round Review

The SIG SAUER X-Ray3 Pistol Sight Set, No. 6 Green Front, No. 8 Rear, round: Not Just Another Review

After years of relying on standard iron sights, the need for enhanced low-light visibility and faster target acquisition became a persistent itch. For my SIG Sauer P320, which has become my go-to for training and occasional carry, the factory white dots, while functional in broad daylight, left much to be desired when the sun dipped or the indoor range lights flickered. This led me to explore aftermarket options, and the SIG SAUER X-Ray3 Pistol Sight Set, No. 6 Green Front, No. 8 Rear, round quickly rose to the top of my consideration list, promising a significant upgrade. The allure of a robust tritium system combined with a high-contrast front sight seemed like the perfect solution to bridge the gap between day and night performance. My initial impression upon unboxing was one of solid craftsmanship; the metal construction felt substantial, and the tritium vials were clearly protected. While I briefly considered other brands, the SIG SAUER pedigree and the specific “round” notch design of the rear sight, which users mentioned aided focus, made this set the clear frontrunner. It felt like a genuine step up in firearm enhancement, a subtle but crucial improvement.


Real-World Testing: Putting SIG SAUER X-Ray3 Pistol Sight Set, No. 6 Green Front, No. 8 Rear, round to the Test

First Use Experience

My testing began at my local indoor range, where lighting conditions can be notoriously inconsistent, often mimicking dusk or overcast skies even during the day. Installation was straightforward, though I opted to use a dedicated sight-pusher tool to ensure proper alignment and avoid damaging the slide dovetails. The immediate difference was striking; the green front sight practically leaped out, even in the dimmer corners of the range. The round rear sight notch, a feature I was particularly keen to try, did indeed make it easier to center the front sight dot quickly, a welcome change from the more traditional square notch.

Extended Use & Reliability

Over several months, these X-Ray3 sights have become a permanent fixture on my P320. I’ve subjected them to numerous range sessions, carried the pistol concealed through a variety of weather, and even performed some impromptu slide-racking drills against convenient edges when needed. The steel surrounds protecting the tritium vials have proven their worth, offering confidence that these sights can handle the rigors of daily life. I’ve noticed no degradation in the tritium’s glow, nor any loosening or shifting of the sights themselves. Cleaning the pistol is also no more complicated than before; the sight surfaces wipe clean easily, and I haven’t encountered any issues with solvents affecting the tritium or polymer components. Compared to the basic white dots I replaced, the reliability and performance of these SIG SAUER sights are in a different league, particularly in variable lighting.

Breaking Down the Features of SIG SAUER X-Ray3 Pistol Sight Set, No. 6 Green Front, No. 8 Rear, round

Specifications

The SIG SAUER X-Ray3 Pistol Sight Set, No. 6 Green Front, No. 8 Rear, round is engineered for rapid target acquisition in all lighting conditions. It features a 3-Dot tritium system, with the front sight dot glowing a vibrant green and the rear dots also presenting a visible green hue. The front sight is characterized by an oversized, chemical-resistant fluorescent polymer dot outlined in high-contrast green, designed to be exceptionally visible. The rear sight boasts a blacked-out, subtle outline around its green tritium dots, with a defining round U-shaped notch.

These sights are constructed from durable metal, specifically steel, providing robust protection for the tritium inserts against recoil and environmental factors. The steel housing is designed for longevity and has been torture tested to 20,000 rounds, underscoring their resilience. The tritium illumination boasts a half-life of over 10 years, ensuring consistent visibility for well over a decade. These sights are designed for dovetail mounts, a standard for many handguns, and are compatible with a range of SIG Sauer models including the P227, P938, P225, P220, P226, P238, P229, and P320. The front sight color is distinctly green, while the rear sight color is also specified as green for the tritium dots.

Performance & Functionality

The core function of the SIG SAUER X-Ray3 Pistol Sight Set, No. 6 Green Front, No. 8 Rear, round is to improve target acquisition, and it excels in this regard. The green front sight is incredibly easy to pick up, even in full daylight where the high-contrast outline prevents it from washing out. In low light and complete darkness, the tritium glow is bright, steady, and perfectly aligned with the rear dots, creating a clear, intuitive sight picture. The “round” U-shaped rear notch, as many users have noted, is a subtle but significant improvement for those of us with maturing eyesight; it allows the eye to naturally center the front sight dot with greater ease and less conscious effort.

The “blacked-out” rear sight, as described, is a key design element. In daylight, the rear sight tends to recede visually, making the bright green front dot even more prominent. This configuration significantly reduces the cognitive load when acquiring a target, especially under stress. The durability implied by the 20,000-round test seems well-founded given the solid construction. I have experienced no flickering or fading of the tritium, which is a testament to the quality of the vials and their protective casing.

Design & Ergonomics

The design of these sights is a clear step up from basic factory offerings. The steel construction feels substantial and robust, offering a premium feel that inspires confidence. The machining is precise, with clean edges and a well-finished matte black surface that complements most firearms. The round rear sight notch is a departure from the more common square notch, and in practice, it proves to be more forgiving and intuitive for rapid sight alignment. It gently guides the eye to center the front dot, minimizing the common tendency to have the front sight floating in the notch rather than precisely centered.

The fluorescent polymer front dot is not just for show; its texture and slightly raised profile add to its pick-up-ability. It’s also noted as being chemical resistant, which is a practical consideration for any firearm owner who performs regular cleaning and maintenance. While not overtly ergonomic in the sense of a grip, the design of the rear sight also lends itself well to one-handed slide manipulation, a capability many users look for in duty or carry pistols.

Durability & Maintenance

Based on the manufacturer’s specifications and my own experience, the SIG SAUER X-Ray3 Pistol Sight Set, No. 6 Green Front, No. 8 Rear, round is built for the long haul. The steel housing is a significant factor in its perceived durability, offering a strong barrier against impacts and the stresses of recoil. The 10-year tritium warranty is a powerful statement of confidence from SIG SAUER, indicating they expect these sights to perform reliably for well over a decade. Maintenance is refreshingly simple: clean the firearm as usual, ensuring the sight surfaces are free of debris. The materials used resist common cleaning solvents, so there’s no need for special care. The only potential point of concern, as noted by some users on smaller platforms like the P938 or P238, is the careful installation process, where spring tension can be a factor if not handled correctly.

Accessories and Customization Options

The SIG SAUER X-Ray3 Pistol Sight Set, No. 6 Green Front, No. 8 Rear, round is essentially a direct replacement part, meaning its primary “accessory” is its compatibility with a range of SIG Sauer pistols. It does not come with additional accessories in the traditional sense, such as cleaning kits or specialized tools. However, the customization aspect lies in its ability to transform the sighting system of compatible firearms. For those with firearms that accept dovetail sights, these represent a significant upgrade. The set is designed to integrate seamlessly with the firearm’s existing dovetail cuts, requiring no permanent modification to the pistol itself. This makes it a highly practical and reversible upgrade for users looking to enhance their firearm’s performance without altering its fundamental design.
