The Kensight Springfield Serrated Blade U Tritium Sight: A Review After Real Use
For years, my Springfield Armory 1911 has been a faithful companion, performing admirably in a variety of demanding environments. However, as my training evolved and my appreciation for low-light shooting capabilities grew, I found myself increasingly frustrated with its stock iron sights. The need for a reliable, self-illuminating rear sight became paramount, and after considerable research, I landed on the Kensight Springfield Serrated Blade U Tritium Sight. This particular model from Kensight promised a significant upgrade in sight picture clarity and durability, directly addressing my primary concerns.
My journey to this specific sight began with a few late-night dry-fire drills that highlighted the limitations of my existing setup. In dimly lit conditions, acquiring a consistent sight picture was a slow, often inaccurate process. I considered a few other tritium sights, but the Kensight’s unique tritium lamp installation method and the specific “U” shaped notch design caught my attention. The promise of a sight that could withstand the rigors of active use while offering improved low-light visibility was too enticing to ignore.
Upon receiving the Kensight Springfield Serrated Blade U Tritium Sight, my initial impression was one of robust craftsmanship. The sight felt solid and substantial, milled from what felt like high-quality steel. The serrations on the blade were crisp, and the overall finish exuded a professional, no-nonsense demeanor. It immediately suggested a product built for function over flash, which is precisely what I look for in my gear.
Real-World Testing: Putting Kensight Springfield Serrated Blade U Tritium Sight to the Test
First Use Experience
My initial testing grounds were the familiar confines of my home range, specifically a dedicated low-light training area. This setup allows for realistic simulations of dusk and night shooting without the complexities of full darkness. I also conducted some basic field drills on a crisp autumn evening, where natural light faded rapidly.
The performance in these varying conditions was immediately apparent and impressive. The tritium lamp, even in ambient twilight, provided a distinct, easily visible dot against the dark background. This significantly sped up my target acquisition compared to my previous sights. The serrated blade also helped reduce glare from any ambient light sources, a subtle but welcome feature that improved sight picture consistency.
Ease of use was surprisingly high, given the precision nature of sight installation. While professional installation is always recommended for optimal alignment and safety, the design itself felt intuitive. The click adjustments for windage and elevation offered satisfying tactile feedback, assuring me that each adjustment was positive and precise.
My only minor surprise was how the sight sat slightly higher than my factory rear sight. This wasn’t a negative, but it did require a brief period of adjustment for my natural point of aim. It took a few magazines of controlled drills to fully acclimate to this new profile, ensuring I wasn’t over or under-compensating.
Extended Use & Reliability
After several months of consistent use, this rear sight has proven its mettle. It has accompanied me on multiple range days, countless dry-fire sessions, and even a weekend training course that pushed its limits. The daily task of keeping my primary firearm ready has been made considerably more efficient and effective by this upgrade.
Durability has been exceptional so far. Despite being exposed to the usual workshop dust, occasional cleaning solvent splashes, and the general bumps and knocks associated with a well-used firearm, there are no signs of premature wear. The tritium lamps remain bright and evenly illuminated, showing no dimming or fading, even after being stored in a dark safe for extended periods.
Maintenance has been straightforward, aligning with standard firearm care practices. A light application of oil and a careful wipe-down after each range session are all that’s needed to keep it in pristine condition. The design is such that cleaning around the tritium lamps is not cumbersome, preventing any buildup that might obscure their glow.
Compared to budget aftermarket sights I’ve used in the past, this Kensight unit is in a different league. Those often suffer from imprecise adjustments or tritium lamps that dim over time. This model, on the other hand, feels like a premium component, offering both enhanced functionality and the longevity expected from a serious upgrade.
Breaking Down the Features of Kensight Springfield Serrated Blade U Tritium Sight
Specifications
The Kensight Springfield Serrated Blade U Tritium Sight boasts several key specifications that contribute to its performance. It features a serrated blade designed to minimize glare, enhancing target focus. Crucially, it incorporates Trijicon tritium bars, available in green or yellow, which provide 0.076-inch illumination for low-light conditions.
The sight’s fully adjustable nature is underscored by positive click adjustments for elevation and windage, allowing for precise zeroing. A significant design element is KFS Industries’ patent for installing tritium lamps from the sides, ensuring they are encased on both ends. This 4140 Chrome Moly Steel construction provides robust durability, while its specific profile is noted to sit slightly higher, offering an advantageous sight picture for target shooting.
These specifications translate directly into tangible benefits for the end-user. The Trijicon tritium bars are the star for low-light scenarios, offering a reliable, self-powered glow that doesn’t require batteries. The positive click adjustments mean you can make minute changes to your zero with confidence, knowing each click represents a consistent shift. The side-mounted tritium lamps are a critical feature for longevity, preventing the common issue of lamps loosening and falling out over time, a testament to thoughtful engineering.
Performance & Functionality
In terms of its core function, the Kensight Springfield Serrated Blade U Tritium Sight performs exceptionally well. The primary job of a rear sight is to provide a clear aiming point that aligns with the front sight, and this Kensight unit excels at that. The “U” shaped notch, combined with the serrated blade, creates a distinct sight picture that is easy to focus on, even under pressure.
Its greatest strength lies undoubtedly in its low-light performance. The Trijicon tritium illumination is consistent and visible, transforming a pistol from a “daytime only” tool to one capable of reliable use around the clock. The positive click adjustments are another major strength, offering a tactile confirmation of every windage and elevation change, making zeroing and field adjustments efficient and repeatable.
Where improvement could be considered, it’s minor. While the “U” notch is excellent for rapid acquisition, some purists might prefer a more traditional square notch for the absolute finest precision at extreme distances. However, for its intended purpose – self-defense and general marksmanship – the “U” notch is arguably superior for speed and clarity. The sight’s profile, while beneficial for some shooting styles, might require a slight adjustment period for those accustomed to lower-profile sights.
Design & Ergonomics
The design of this rear sight speaks to a user-focused approach combined with rugged functionality. Crafted from 4140 Chrome Moly Steel, it feels exceptionally robust and well-made. The matte black finish not only looks professional but also aids in reducing glare.
Ergonomically, the sight is designed for efficient use. The serrated blade offers a much-needed anti-glare surface, which is particularly helpful when shooting in bright or variable lighting conditions. The positive click adjustments are easily manipulated, even with gloved hands, providing firm control over windage and elevation.
The U-shaped rear notch is a standout design choice. It provides a generous window around the front sight post, facilitating faster sight alignment during dynamic shooting or in low-light environments. The overall profile, while sitting a bit higher, creates a pleasing visual line that aids in consistent stock weld and sight picture acquisition once you adapt to it.
Durability & Maintenance
Based on its construction and initial performance, the durability of the Kensight Springfield Serrated Blade U Tritium Sight appears to be excellent for its intended lifespan. The 4140 Chrome Moly Steel is a tried-and-true material for firearm components, known for its strength and resistance to wear. The innovative side-mounted tritium lamp installation is a key design feature that directly addresses potential durability issues.
Maintenance is refreshingly simple. Standard firearm cleaning solvents and cloths are sufficient for keeping the exterior clean and functional. The tritium lamps are sealed units, meaning they require no special care beyond keeping the lens surfaces clean. There are no obvious points of failure in the design that would suggest premature wear under typical use.
Potential concerns, though minor, might involve the longevity of the tritium itself, which has a finite lifespan (typically 10-12 years of illumination before diminishing). However, this is an inherent characteristic of tritium technology, not a flaw in Kensight’s manufacturing. Replacement would then be an option to extend the sight’s life further.
Accessories and Customization Options
The Kensight Springfield Serrated Blade U Tritium Sight is primarily a direct replacement part, meaning it doesn’t typically come with a broad array of accessories in the traditional sense. However, the product description does mention that it comes “paired with our Springfield tritium contoured front sight with a serrated blade.” This suggests that purchasing as a set is an option, which is highly recommended for optimal performance and alignment.
Customization options are more focused on the application of the sight. It is explicitly stated that this rear sight is compatible with Novak type front sight dovetail cuts (0.340″ x 60 x 0.075″), making it a versatile upgrade for many customized and factory 1911 pistols. Available tritium colors (green or yellow) also offer a degree of user preference. While not a customization feature of the sight itself, users can choose the front sight blade heights from 0.150” to 0.220” upon request, which is crucial for achieving a proper zero with their chosen ammunition and firearm.
