What Makes the Kensight GI Series Colt M1911-A1 Series 70 Tenon 0.056in Tritium Staked Patridge 1911 Front Sight Click?
For a pistol that has stood the test of time, the 1911 platform, especially the venerable Colt Series ’70, demands specific, quality upgrades. That’s where the Kensight GI Series Colt M1911-A1 Series 70 Tenon 0.056in Tritium Staked Patridge 1911 Front Sight enters the picture, offering a distinct advantage for those seeking enhanced low-light visibility. This front sight is designed as a direct replacement, ensuring a proper fit and function for its intended application.
My own pursuit of this particular sight was driven by a common ailment among classic firearms: a desire to update functionality without compromising the original spirit. While my existing 1911-A1 Series 70 retained its classic charm, its iron sights were less than ideal when the sun dipped below the horizon. I needed a reliable aiming solution that wouldn’t require a complete overhaul of the firearm’s sight system.
Upon first inspection, the sight presented a solid, well-machined appearance. The 4140 Chrome Moly Steel construction felt robust, and the Patridge style blade offered a clean, precise profile. It’s clear this isn’t a flimsy afterthought but a purpose-built component designed for longevity. I had briefly considered other aftermarket front sights, but their proprietary mounting systems or different tenon sizes made them less appealing for a purist’s approach.
This Kensight unit offered immediate promise, a small but significant upgrade that felt like the right step forward. The initial impression was one of quiet confidence, a feeling that this component would integrate seamlessly and perform its duty without fuss.
Real-World Testing: Putting Kensight GI Series Colt M1911-A1 Series 70 Tenon 0.056in Tritium Staked Patridge 1911 Front Sight to the Test
First Use Experience
My testing ground for this sight was primarily my home workshop and, crucially, the familiar steel of my local indoor shooting range. The initial installation was a straightforward affair on my Colt Series ’70 Gold Cup, a pistol known for its precise tolerances. I needed to ensure the 0.056in tenon seated correctly, which it did with a satisfying snugness.
Performance under varied conditions was key. On the range, I focused on how the sight picture presented itself during both bright daylight and the dimmer conditions of an indoor range. The serrated blade proved its worth immediately, cutting down on glare and offering a remarkably clear view against the target. This optic was intuitive from the start; there was no significant learning curve, just a better sight picture.
One minor surprise was how well it paired with a standard MIL-SPEC rear sight, not just the specific Kensight model it’s recommended with. This versatility is a definite plus.
Extended Use & Reliability
After several months and countless range trips, this Kensight front sight has become a fixture on my M1911. It has endured the occasional bump against a workbench and the general vibrations of live fire without any noticeable degradation in performance. The green tritium insert, manufactured by Cammenga, remains consistently bright, a testament to its quality and expected lifespan.
Durability is evident; there are no signs of the 4140 Chrome Moly Steel cracking or showing undue wear. The white PVC outline around the tritium remains intact and continues to provide excellent contrast. Cleaning is as simple as cleaning any other part of the slide, and it has required no special maintenance beyond that. Compared to older, non-tritium sights I’ve used, this unit offers a significant advantage in low-light scenarios without sacrificing daytime accuracy.
Breaking Down the Features of Kensight GI Series Colt M1911-A1 Series 70 Tenon 0.056in Tritium Staked Patridge 1911 Front Sight
Specifications
The Kensight GI Series Colt M1911-A1 Series 70 Tenon 0.056in Tritium Staked Patridge 1911 Front Sight boasts a few key specifications that define its utility. The 0.056in tenon is specifically engineered to fit the Series ’70 Colt pistols, ensuring a precise, factory-like fit. Its height is measured at just .150″ tall, a critical dimension for proper sight alignment, particularly when paired with a standard MIL-SPEC rear sight.
The blade itself measures .150″ tall by .118″ wide, providing a substantial yet manageable aiming point. The core of its low-light capability lies in the green tritium insert, a .077″ diameter vial made and installed by Cammenga, which is enclosed by a bright white PVC outline. This entire unit is constructed from durable 4140 Chrome Moly Steel, finished in a classic black to minimize glare and match most firearm finishes.
Performance & Functionality
This Kensight front sight excels at its primary function: providing a clear and reliable aiming point, day or night. The Patridge style blade with its vertical rear edge is exceptionally well-suited for target shooting, offering a crisp sight picture that minimizes parallax error. The addition of a finely serrated face on the blade is a masterstroke, drastically reducing sun glare during bright outdoor sessions.
Its strengths lie in its accuracy enhancement and its practical low-light performance. The tritium insert glows reliably, allowing for swift target acquisition when ambient light is minimal. The main weakness, if one can call it that, is its inherent fixed nature; it’s designed for a specific platform and height. It meets and exceeds expectations for a factory-style replacement with enhanced functionality, especially considering its price point relative to other tritium sights.
Design & Ergonomics
The design philosophy here is clearly functional and classic. The black finish is understated and practical, resisting reflections that could interfere with aiming. The 4140 Chrome Moly Steel construction lends a satisfying heft and perceived durability; this isn’t a sight that feels like it will bend or break easily.
Ergonomically, it’s a fixed blade sight, meaning its primary interaction is visual. The serrated face improves visual acquisition by reducing glare, and the clean lines of the Patridge blade allow for precise alignment with the rear sight. The white outline around the tritium serves as an excellent contrast point, drawing the eye quickly to the aiming point.
Durability & Maintenance
Given its 4140 Chrome Moly Steel construction and the robust nature of the Cammenga tritium vial, this Kensight front sight is built for the long haul. Under typical range use and concealed carry conditions, it should easily last for its rated tritium lifespan, which is typically 10-12 years.
Maintenance is virtually non-existent beyond regular firearm cleaning. There are no moving parts to worry about, and the staking of the tritium vial appears very secure. Potential failure points would be extreme impact or exposure to harsh chemicals, neither of which are typical for its intended use.
Accessories and Customization Options
The Kensight GI Series Colt M1911-A1 Series 70 Tenon 0.056in Tritium Staked Patridge 1911 Front Sight comes as a singular component. It is designed to pair with existing rear sights, and Kensight specifically mentions its synergy with their item 860-202 rear sight, but it also works with any standard fixed MIL-SPEC .330″ wide x .115″ deep rear sight. There are no additional accessories included or readily apparent customization options beyond ensuring it’s correctly installed on the appropriate firearm.
