Kensight DAS Adjustable Rear 1911 Tritium Night Sight Review

The Honest Truth About the Kensight DAS Adjustable Rear 1911 Tritium Night Sight

For years, I’ve relied on reliable sights for my 1911 platforms, whether it’s on the range, during demanding training courses, or for general preparedness. My trusty Gordon MC 1911 SC has seen its share of upgrades, but the factory sights were beginning to feel like a weak link, especially in anything less than ideal lighting. I needed something that offered more than just a basic aiming point, something that could adapt and perform when conditions were challenging. This led me to the Kensight DAS Adjustable Rear 1911 Tritium Night Sight.

The initial impression upon unboxing this rear sight was one of solid craftsmanship. It’s forged from 4140 Chrome Moly Steel, which immediately feels more substantial and durable than many polymer or cast alternatives. The serrated blade and the way the tritium vials are nestled within the white dots suggest a thoughtful design focused on practical performance. While I considered some of the more widely advertised brands, I was drawn to the adjustability and the promise of a robust tritium solution for my specific firearm. My first reaction was a sense of quiet optimism; this looked like a piece of equipment built for purpose, not just aesthetics.

Real-World Testing: Putting Kensight DAS Adjustable Rear 1911 Tritium Night Sight to the Test

First Use Experience

My testing ground was primarily my local indoor and outdoor shooting ranges, environments that simulate low-light and standard daylight conditions effectively. I also carried the pistol with the installed sight for a few weeks to gauge its snag potential and everyday robustness. The installation process itself provided the first real insight: while advertised to fit Novak LoMount dovetails, it required some careful fouling for a truly precise fit in my specific pistol’s slide. This is not uncommon with aftermarket sights, especially on certain production 1911s, but it meant I couldn’t just slap it in and go.

Once fitted, the adjustability was immediately apparent. The windage and elevation clicks were positive and distinct, allowing for on-the-fly zeroing. However, a minor quirk emerged during this initial setup: the windage adjustment, while precise in its clicking, seemed to have a point where it wouldn’t quite move past a certain internal stop as intended without a bit more persuasion. This is something to be aware of, especially if you’re installing it yourself. The tritium lamps offered a distinct advantage in the dimly lit indoor range, providing a clear, three-dot picture that was much easier to acquire than my previous sights.

Extended Use & Reliability

Over the course of several months, this DAS rear sight has become a permanent fixture on my 1911. It has endured numerous range sessions, dusty outdoor excursions, and the general wear and tear of being carried. The 4140 Chrome Moly Steel construction has proven its worth; there are no visible cracks, significant scuffs, or corrosion, even after exposure to light moisture and temperature fluctuations. The serrated blade does an admirable job of reducing glare, particularly under harsh overhead lights or direct sunlight.

Maintenance is straightforward. A light wipe-down with a silicone cloth keeps it clean, and a drop of optic-specific lubricant on the adjustment screws has kept them moving smoothly. The tritium lamps, a key selling point, have maintained their glow. While I haven’t had it long enough to comment on their 10+ year lifespan, they remain bright and functional. Compared to other adjustable rear sights I’ve used, this Kensight unit feels robust. It’s not as sleek as some competition-grade sights, but its practical durability is impressive for its price point. The user feedback I’d seen mentioning fitment issues and potential adjustment quirks did prove partially true, highlighting the importance of patience and sometimes a bit of gunsmithing skill for a perfect installation.

Breaking Down the Features of Kensight DAS Adjustable Rear 1911 Tritium Night Sight

Specifications

The Kensight DAS Adjustable Rear 1911 Tritium Night Sight is designed for the ubiquitous 1911 Platform and is specifically crafted to fit the popular Novak LoMount rear sight dovetail cut. This makes it compatible with a vast number of factory and custom 1911 pistols. The sight blade is partially serrated and slanted, a design choice aimed at reducing glare which I found to be effective under various lighting conditions. Its construction is from 4140 Chrome Moly Steel, a material known for its strength and wear resistance, ensuring longevity.

This rear sight features two self-luminous Green Tritium Lamps, which are crucial for low-light visibility. These are paired with two High Visibility White Dots on the blade, forming a classic 3-dot sight picture. The sight is fully adjustable for both windage and elevation, with positive, precise click adjustments that allow for reliable POI (point of impact) changes. The manufacturer specifies a 0.118” wide blade and a contoured base designed for a clean installation on round-top slides, minimizing the need for extensive filing, though my experience indicated some fitting was still necessary. The overall color is a practical Black.

Performance & Functionality

The primary function of any sight is to help the shooter acquire a target quickly and accurately. In this regard, the Kensight DAS Adjustable Rear 1911 Tritium Night Sight performs admirably, especially considering its adjustability and tritium illumination. The combination of white dots in daylight and tritium in low light creates a very versatile aiming system. The white dots are bright enough for daytime use, and the tritium lamps provide a discernible glow in dim conditions, allowing for a consistent sight picture across different lighting scenarios.

The positive click adjustments for windage and elevation are a significant strength. They offer tactile feedback and allow for precise zeroing, which is essential for any shooter who values accuracy. However, the performance is slightly tempered by the fitment variability I encountered. While the adjustments themselves are well-defined, the initial fit in the dovetail required filing, and there was a minor stickiness in one direction of the windage adjustment that required careful manipulation. Despite these minor hurdles, once zeroed, the sight holds its adjustments reliably. It meets expectations for a tritium adjustable rear sight but requires careful installation.

Design & Ergonomics

The design of this Kensight sight is rooted in practicality. The use of 4140 Chrome Moly Steel gives it a substantial feel, suggesting it can withstand the rigors of hard use. The partially serrated blade is a thoughtful ergonomic touch, effectively breaking up reflections that could otherwise obscure the sight picture. The integration of the Green Tritium Lamps within the white dots is well-executed, offering a clear, distinct aiming point without being overly distracting.

Ergonomically, the sight is designed to blend with the lines of a 1911 slide. The contoured base is intended to provide a clean transition. While the sight itself is functional, its overall ergonomics are largely dictated by its intended use – aiming a pistol. The real ergonomic consideration comes during installation, where the fit and finish of the dovetail are paramount. Any sharp edges or improper fit can lead to discomfort or snagging, though this unit, once properly installed, sits flush and doesn’t present significant snagging issues. The clicks for adjustment are firm, providing good tactile feedback without being difficult to manipulate.

Durability & Maintenance

Durability is where the Kensight DAS Adjustable Rear 1911 Tritium Night Sight truly shines, primarily due to its 4140 Chrome Moly Steel construction. This material is inherently robust and resistant to wear, making it suitable for duty or hard use scenarios. The tritium lamps are sealed and designed to last for many years, typically advertised with a lifespan of over 10 years, providing a long-term, maintenance-free illumination source.

Maintenance is minimal. A simple wipe-down to remove debris and occasional lubrication of the adjustment screws is all that’s generally required. The absence of complex electronic components means there are fewer potential failure points. The main concern for longevity would be the integrity of the dovetail fit and the adjustment mechanisms. As long as the sight is installed correctly and the adjustment screws are not overtightened or forced, it should offer excellent durability. There are no readily apparent weak points that would suggest premature failure under normal use for a steel sight.

Accessories and Customization Options

The primary “accessory” included with the Kensight DAS Adjustable Rear 1911 Tritium Night Sight is, of course, the tritium illumination itself, enhancing its functionality in low light. The product description mentions it pairs with their ProGlo tritium night sight with a lumi orange outline for the front sight, suggesting a potential system approach. However, this review focuses solely on the rear sight. It’s designed to fit standard Novak LoMount dovetails and standard Novak-type front sight dovetail cuts (0.330″ x 65 x 0.075″).

This means it’s compatible with a wide range of 1911 Platform pistols that utilize this common sight cut. While Kensight offers various front sight options, this rear sight itself doesn’t have extensive user customization beyond its windage and elevation adjustments. The tritium lamps are not user-replaceable, nor are the white dots. The sight’s utility is enhanced by pairing it with an appropriate front sight that complements its aiming characteristics and illumination type.

Pros and Cons of Kensight DAS Adjustable Rear 1911 Tritium Night Sight

Who Should Buy Kensight DAS Adjustable Rear 1911 Tritium Night Sight?

This Kensight DAS adjustable rear sight is an excellent choice for 1911 owners who prioritize accurate and reliable aiming in all lighting conditions. It’s particularly well-suited for individuals who participate in concealed carry, duty applications, competition shooting, or simply enjoy target shooting and want a significant upgrade over basic factory sights. If you frequently find yourself shooting in dawn, dusk, or indoor ranges with dim lighting, the tritium illumination will be a game-changer.

However, those who expect a completely drop-in installation on every 1911 without any potential modification might want to proceed with caution or budget for professional gunsmithing. If you are uncomfortable with minor fitting or possess limited experience with firearm modifications, consulting a qualified gunsmith is recommended. For anyone looking for a robust, adjustable, and luminous aiming solution for their 1911, this sight is a strong contender. A quality front sight from Kensight or a similar manufacturer with a tritium insert would be a wise complementary purchase to complete the system.

Conclusion on Kensight DAS Adjustable Rear 1911 Tritium Night Sight

The Kensight DAS Adjustable Rear 1911 Tritium Night Sight is a robust and highly functional upgrade for any 1911 owner seeking improved aiming capabilities. Its 4140 Chrome Moly Steel construction speaks to its durability, while the integrated Green Tritium Lamps and white dots ensure effective performance from bright daylight to near darkness.

At a price point of $203.63, it offers a compelling value proposition for an adjustable tritium rear sight from a reputable manufacturer.
