The Final Word on the Kensight DAS Flat Profile Adjustable Rear 1911 Night Sight
For years, I’ve relied on my gear to perform without question across a spectrum of demanding environments. When it came to upgrading the sights on my trusty 1911, precision and low-light capability were paramount. The Kensight DAS Flat Profile Adjustable Rear 1911 Night Sight presented itself as a robust solution for enhanced target acquisition, promising adjustability and visibility when it matters most. My previous sights, while functional, lacked the adaptability needed for varied shooting scenarios, and their performance in dim light was frankly disappointing. I considered some fixed tritium sights, but the desire for on-the-fly adjustments steered me toward this Kensight model. A quick initial inspection revealed a solid construction, hinting at a reliable upgrade for my platform.
Real-World Testing: Putting Kensight DAS Flat Profile Adjustable Rear 1911 Night Sight to the Test
First Use Experience
My initial testing took place on a familiar indoor range, under controlled lighting conditions, and then expanded to an outdoor range during the twilight hours. This rear sight was installed on my personal 1911, a platform I’m intimately familiar with. I specifically chose these scenarios to evaluate the sight’s adjustability and its low-light performance, which are its key selling points. The windage and elevation adjustments were surprisingly tactile and offered positive clicks, making the process of zeroing straightforward. I experienced no initial issues or unexpected quirks during the first few range sessions.
Extended Use & Reliability
Over several months of intermittent use, the Kensight DAS Flat Profile Adjustable Rear 1911 Night Sight has proven its mettle. It’s accompanied me on numerous range days and has spent time in my workshop, waiting for other projects. The durability is evident; despite a few accidental bumps against a workbench and exposure to the occasional bit of workshop dust, there’s no discernible wear on the 4140 Chrome Moly Steel construction. Maintenance has been minimal, usually just a quick wipe-down with a cleaning cloth and a drop of lubricant on the adjustment screws, which has kept its operation smooth. Compared to the fixed sights I’ve used before, this Kensight optic offers a clear advantage in versatility and low-light effectiveness.
Breaking Down the Features of Kensight DAS Flat Profile Adjustable Rear 1911 Night Sight
Specifications
The Kensight DAS Flat Profile Adjustable Rear 1911 Night Sight is engineered with versatility and durability in mind. It features a fully adjustable mechanism for both windage and elevation, crucial for precise POI (Point of Impact) adjustments. This adjustability is facilitated by positive, tactile click adjustments that ensure reliable and consistent changes. The sight blade itself is partially serrated to minimize glare, a feature that significantly improves target acquisition in bright daylight.
For low-light conditions, the sight incorporates two self-luminous Green Tritium Lamps nestled within two High Visibility White Dots. This combination creates a clear 3-dot sight picture that is quick to acquire in dim environments. The rear sight is designed to pair with a standard tritium flat base front sight, and the set comes with a 0.200” tall blade. However, Kensight offers blade heights from 0.150” to 0.220”, allowing for customization based on individual firearm and load combinations.
Crucially, this rear sight is compatible with the Novak type front sight dovetail cuts, specifically measuring 0.330″ x 65 x 0.075″. This common dovetail size is frequently found on both customized and factory 1911 pistols, ensuring broad compatibility. The Kensight DAS specifically fits the popular Novak LoMount rear sight dovetail, a standard on many production and custom 1911 models. The material is robust 4140 Chrome Moly Steel, finished in black, promising longevity and resistance to the elements and wear.
Performance & Functionality
The primary function of a rear sight is to provide an aiming point, and this Kensight model excels at that, especially when light conditions are less than ideal. The Tritium lamps offer a consistent, faint glow that is perfectly visible in complete darkness, while the white dots provide a distinct outline during daylight hours. The adjustable windage and elevation are genuinely useful; I was able to fine-tune my shot placement quickly during testing without needing to remove the slide or use specialized tools, beyond a small screwdriver. This on-the-fly adjustability is a significant performance benefit for those who engage in different shooting disciplines or switch ammunition types.
The partially serrated blade is another functional strength. It effectively diffuses light, reducing distracting reflections that can obscure the target. This feature alone makes a noticeable difference during bright outdoor shooting sessions. The positive detents on the adjustment screws provide confidence that your settings will hold firm. I haven’t encountered any instances where the adjustments shifted unexpectedly.
Design & Ergonomics
From a design perspective, the Kensight DAS Flat Profile Adjustable Rear 1911 Night Sight is built with a practical, no-nonsense aesthetic. The 4140 Chrome Moly Steel provides a substantial feel, indicating good build quality and inherent durability. The black finish is understated and blends well with most 1911 frames. The profile of the sight is flat, which generally minimizes snagging during a draw from concealment, a consideration for duty or carry applications.
Ergonomically, the serrations on the blade and the overall shape of the sight are well-executed. They don’t interfere with the shooting hand or draw stroke. The adjustment mechanisms, while small, are accessible enough to be manipulated with a tool, but not so exposed that they are easily bumped out of place. The combination of the tritium and white dots is a classic and effective design for all-around visibility.
Durability & Maintenance
The 4140 Chrome Moly Steel construction is a strong indicator of the Kensight DAS Flat Profile Adjustable Rear 1911 Night Sight‘s durability. This material is known for its strength and resistance to wear and corrosion. After my testing period, which included handling, cleaning, and repeated adjustment of the sight, there have been no signs of stripping on the adjustment screws or any structural compromise. The tritium lamps are sealed and designed for longevity, typically lasting 10-12 years before their luminescence begins to fade significantly.
Maintenance is straightforward. A simple cleaning of the exterior surfaces keeps it looking good. Periodically, a light application of gun oil on the adjustment mechanisms can ensure smooth operation. There are no complex parts that require specialized tools for routine care. The design inherently protects the internal adjustment mechanisms from excessive debris ingress, which is a major plus in less-than-pristine environments.
Accessories and Customization Options
The Kensight DAS Flat Profile Adjustable Rear 1911 Night Sight is typically sold as a rear sight unit, intended to be paired with a compatible front sight. The product description notes it comes paired with our standard tritium flat base front sight with a serrated blade, and the set is sold with a 0.200” tall blade. This integrated approach simplifies the upgrade process for users.
The primary customization option lies in the adjustable nature of the sight itself and the availability of different blade heights upon request. This allows shooters to tailor the sight’s height to their specific firearm and ammunition preferences, which is a significant advantage over fixed sights. Compatibility with the Novak LoMount dovetail means it integrates seamlessly with a vast number of existing 1911 pistols without requiring custom machining. While no additional tools are included, a standard gunsmith screwdriver is all that’s needed for adjustments.

Who Should Buy Kensight DAS Flat Profile Adjustable Rear 1911 Night Sight?
This rear sight is an excellent choice for 1911 owners who frequently shoot in varying light conditions and desire the ability to fine-tune their point of impact. It’s ideal for range shooters, competitive handgun enthusiasts, and law enforcement or self-defense practitioners who want enhanced accuracy and visibility. If your 1911 is already equipped with or designed for Novak-style sights, this offers a significant upgrade.
Individuals who are looking for a simple, fixed sight solution or whose firearms do not use the Novak cut might want to look elsewhere.

For maximum effectiveness, pairing this rear sight with a matching Kensight tritium front sight is highly recommended, and having a reliable set of gunsmith screwdrivers is essential for making adjustments.
