Kensight DAS Serrated Blade Adjustable Rear 1911 Night Sight Review

Here’s What You’ll Love (or Not) About the Kensight DAS Serrated Blade Adjustable Rear 1911 Night Sight

For years, my 1911s have been reliable companions, but upgrading their sights has always been a pursuit of better low-light performance and more precise zeroing. That’s what led me to the Kensight DAS Serrated Blade Adjustable Rear 1911 Night Sight. The promise of a fully adjustable tritium sight that could handle both daylight and darkness, coupled with a serrated blade for glare reduction, sounded like the perfect solution for my needs. My previous setup, while functional, lacked the finer adjustments and low-light capability I was increasingly seeking for defensive training scenarios.

Upon unboxing this rear sight, my initial impression was one of robust craftsmanship. The 4140 Chrome Moly Steel felt substantial, exuding a sense of durability that is crucial for firearm components. The serrated blade itself has a finely machined finish, and the adjustment knobs provide satisfyingly positive clicks. It immediately felt like a significant step up from some of the more utilitarian sights I’ve encountered. I had briefly considered a competitor offering a similar adjustable tritium rear, but their less aggressive serrations and slightly higher price point made this Kensight model the more compelling choice. My first reaction was a genuine sense of anticipation, a feeling that a common issue had finally found a well-engineered solution.

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

First Use Experience

My initial testing of this rear sight took place on the range, specifically during twilight and under controlled low-light conditions in my workshop. The goal was to assess its daylight visibility, its tritium glow in darkness, and the precision of its adjustments. Installation required careful fitting into the Novak LoMount dovetail on my 1911, but once seated, it felt secure.

The positive click adjustments for both elevation and windage were immediately apparent and incredibly satisfying. Each click made a discernible difference at 25 yards, allowing for very fine-tuning of my point of impact. Even with some ambient dust on the range, the sight remained visible, and the serrated blade did an admirable job of cutting down on glare from overhead lights.

Extended Use & Reliability

After several weeks of consistent range trips and dry-fire practice, this Kensight optic has proven its mettle. It’s become a permanent fixture on my primary defensive 1911, where it has endured repeated cycling, the occasional minor bump, and exposure to workshop environments without any degradation in performance.

The Trijicon tritium vials are still glowing brightly, providing a reliable aiming point when ambient light is scarce. There are no signs of wear on the steel construction, and the adjustment mechanisms remain crisp and precise, with no looseness developing. Compared to some other adjustable sights I’ve used that eventually developed slop, this model feels exceptionally solid. Maintenance has been minimal; a quick wipe-down with a soft cloth is all that’s needed to keep it clean and functional.

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

Specifications

The Kensight DAS Serrated Blade Adjustable Rear 1911 Night Sight is constructed from 4140 Chrome Moly Steel, a material known for its strength and durability, essential for enduring the recoil of a 1911 pistol. It features a serrated blade profile designed to minimize glare during bright shooting conditions. The unit is a fully adjustable tritium day/night sight, meaning it incorporates a self-illuminating tritium vial for low-light aiming.

This rear sight is specifically designed to fit the popular Novak LoMount rear sight dovetail cut, a common standard on many 1911 platforms. The product description notes it requires a minimum 0.230″ front sight height, and typically comes bundled with a front sight of that height, ensuring proper sight radius alignment. The tritium dots are available in Green or Yellow with a 0.076″ Trijicon tritium dot size, featuring a white outline for enhanced daylight contrast.

Performance & Functionality

The primary job of this rear sight is to provide accurate aiming capabilities in a wide range of lighting conditions, and it excels at this. The adjustable elevation and windage are exceptionally precise, allowing for minute adjustments to achieve a perfect zero. I found it very easy to dial in my loads and hold, which directly translated to tighter groups on the target.

Its greatest strength is undoubtedly its dual-nature performance; it’s as effective on a bright sunny day as it is in near-total darkness. The serrated blade significantly reduces the distracting glint that can occur with highly polished sights, allowing for quicker target acquisition. The main weakness, if one can call it that, is its dependency on tritium for night vision, which has a finite lifespan, though this is a characteristic of all tritium sights.

Design & Ergonomics

The design of this rear sight is a harmonious blend of robust utility and refined function. The 4140 Chrome Moly Steel construction gives it a substantial feel, reassuring you of its toughness. The serrated blade isn’t just functional; it adds a subtle visual appeal that complements the classic lines of a 1911.

Ergonomically, the sight is well-designed for its purpose. The positive click adjustments are easy to manipulate with a fingertip or a small tool, even with gloves on, and the audible and tactile feedback is excellent. The height of the sight, described as sitting up a bit higher, provides a very good sight picture, particularly for competition or target shooting where a clear, unobstructed view is paramount.

Durability & Maintenance

Based on its construction and the materials used, the Kensight DAS Serrated Blade Adjustable Rear 1911 Night Sight is built for long-term durability. The 4140 Chrome Moly Steel is highly resistant to wear and corrosion, making it suitable for various environments. Under typical use for a firearm component, I expect this sight to last for many years, potentially outlasting the tritium illumination itself.

Maintenance is straightforward. A simple cleaning with a non-abrasive cloth and perhaps a touch of gun oil on the adjustment threads every so often is sufficient. There are no complex parts to worry about, and its robust build suggests it can handle the occasional drop or rough handling that can happen in the field or on the bench. Potential failure points would likely be related to extreme abuse, but for its intended application, it appears exceptionally sound.

Accessories and Customization Options

The primary “accessory” that often comes with this rear sight is the matching front sight, typically a 0.230″ tall tritium front sight, which is crucial for ensuring a proper sight radius and alignment. This creates a complete day/night aiming solution.

While the sight itself isn’t a platform for extensive physical customization, its adjustability is its key feature. The ability to precisely adjust elevation and windage means users can customize their point of impact to perfectly match their ammunition, shooting style, or specific firearm. Compatibility is also a significant factor; its design to fit the Novak LoMount rear sight dovetail cut ensures it integrates seamlessly with a vast number of popular 1911 models from manufacturers like Colt, Springfield Armory, Wilson Combat, and STI.

Pros and Cons of Kensight DAS Serrated Blade Adjustable Rear 1911 Night Sight

Who Should Buy Kensight DAS Serrated Blade Adjustable Rear 1911 Night Sight?

This adjustable rear sight is an excellent choice for experienced 1911 owners who demand precision and versatility from their firearm’s aiming system. It’s particularly well-suited for competition shooters who need to fine-tune their zero for different distances or loads, and for individuals focused on defensive training, especially those practicing under varying light conditions. Those who frequently shoot at dawn, dusk, or in dimly lit indoor ranges will greatly benefit from the tritium feature.

Those who should probably skip this product are individuals seeking a simple, inexpensive, fixed-sight upgrade, or those whose firearms do not feature the Novak LoMount rear sight dovetail cut. If your primary use case is exclusively in brightly lit environments and you don’t require night-time aiming capability, a less expensive fixed tritium or even a fiber-optic sight might suffice. For optimal use, ensuring you have a compatible front sight of at least 0.230″ height is a must.

Conclusion on Kensight DAS Serrated Blade Adjustable Rear 1911 Night Sight

The Kensight DAS Serrated Blade Adjustable Rear 1911 Night Sight represents a significant upgrade for any 1911 platform looking for enhanced accuracy and low-light capability. Its robust construction from 4140 Chrome Moly Steel ensures longevity, while the precise adjustable features and serrated blade provide excellent performance across varied lighting. The inclusion of Trijicon tritium makes it a standout choice for defensive applications and serious target practice.

Considering its advanced features, durable build, and the quality of its components, the price of $188.74 feels justified. It offers a level of precision and adaptability that is hard to find in more basic sight options. I would confidently recommend this rear sight to any serious 1911 shooter who values accurate adjustment and reliable low-light aiming. It’s a buy that delivers on its promises and enhances the overall usability and effectiveness of the firearm.
