Kensight Colt Style Formerly Accro Hinge Pin Review

The Real Deal Behind the Kensight Colt Style Formerly Accro Hinge Pin

As someone who’s spent over a decade tinkering, building, and relying on gear across workshops, labs, and the great outdoors, I’ve learned to appreciate the subtle intricacies of even the smallest components. My quest for reliable firearm components led me to the Kensight Colt Style Formerly Accro Hinge Pin. I needed a replacement for the hinge pin on a well-loved Colt-style 1911 sight that had seen better days, and frankly, generic parts just weren’t cutting it anymore. The original pin had developed a bit of play, impacting sight adjustment precision, a no-go for any serious shooter.

Upon receiving the Kensight set, my initial impression was one of professional quality. The 4140 Chrome Moly Steel construction felt robust, a significant step up from the often-softer metals found in cheaper alternatives. I’d considered a few other brands, but Kensight’s reputation for precision machining on their sights tipped the scales. It was a small purchase, but the immediate sense of relief that I’d found a potentially superior replacement was palpable.


Real-World Testing: Putting Kensight Colt Style Formerly Accro Hinge Pin to the Test

First Use Experience

My testing ground for this small but critical part was my home workshop and the local shooting range. I needed to see how these pins would hold up during the initial installation and, more importantly, under the stress of live fire. The installation itself was straightforward; the pins fit snugly into the sight’s dovetail and frame, indicating good manufacturing tolerances.

During the first range session, I fired approximately 50 rounds. The Kensight hinge pins performed flawlessly. The windage and elevation adjustments on the sight remained crisp and distinct, with no hint of looseness developing. The ambient temperature was moderate, and there were no extreme conditions to test beyond standard shooting vibrations.

Extended Use & Reliability

Weeks turned into a couple of months, and this Kensight hinge pin set became a permanent fixture on my Colt-style 1911. I estimate I’ve put another 200 rounds downrange with these pins installed, alongside regular handling and cleaning. The sight adjustments continue to feel as precise as the day I installed them.

Durability is where these parts truly shine. There are absolutely no signs of wear, no slop developing in the hinge mechanism, and the steel shows no cosmetic damage despite being handled and adjusted frequently. Maintenance is as simple as it gets: a light wipe-down with a cleaning cloth and a drop of lubricant during routine firearm cleaning is all that’s required. Compared to previous generic replacements that started to show wear within a few dozen rounds, these Kensight pins are a clear winner.

Breaking Down the Features of Kensight Colt Style Formerly Accro Hinge Pin

Specifications

The Kensight Colt Style Formerly Accro Hinge Pin set comes as a convenient pack of two: one Spirol roll pin and one solid pin. This dual-option packaging is a thoughtful inclusion, offering flexibility for different sight installation preferences or potential future needs. The pins themselves are precisely machined to a length of .563″ and a diameter of .060″.

These dimensions are critical for ensuring a secure and play-free fit within the sight mechanism, which directly impacts the accuracy and repeatability of sight adjustments. The material, 4140 Chrome Moly Steel, is a workhorse alloy known for its strength, hardness, and resistance to wear, making it ideal for components subjected to repeated stress. This is a significant upgrade from lesser steels or alloys, promising longevity and consistent performance.

Performance & Functionality

In its core function, the Kensight Colt Style Formerly Accro Hinge Pin performs admirably. Its primary job is to provide a stable pivot point for the adjustable sight mechanism, and it does this with exceptional precision. The tight tolerances mean that there’s virtually no wobble or play in the hinge, allowing for consistent and accurate adjustments to windage and elevation.

The crisp, audible clicks that accompany each adjustment on Kensight sights are a direct result of the tight manufacturing standards, and these hinge pins are integral to maintaining that responsiveness. While the pins themselves don’t make the adjustments, their quality ensures that the sight mechanism they support can perform at its peak. The only potential “weakness” could be the need for careful installation to avoid damaging the pins or the sight itself, but this is true for any precision component.

Design & Ergonomics

The design of these hinge pins is inherently functional and utilitarian, as expected for such a part. The choice of 4140 Chrome Moly Steel provides a robust and durable feel, reassuring you of its ability to withstand the rigors of firearm use. The finish is typically a matte black, blending seamlessly with most firearm aesthetics without drawing undue attention.

Ergonomically, the pins are designed to be installed and forgotten, their job being to provide a stable foundation for the sight’s adjustments rather than being directly manipulated by the user. However, the precision machining means they seat correctly without requiring excessive force, preventing damage to the delicate dovetail cuts on the sight and firearm. The inclusion of both a roll pin and a solid pin offers a design choice that caters to different installation preferences and potential future repair scenarios.

Durability & Maintenance

Based on my experience and the material used, the Kensight Colt Style Formerly Accro Hinge Pin is built for long-term durability. The 4140 Chrome Moly Steel is inherently resistant to corrosion and wear, meaning these pins should outlast many firearms with proper care. Under normal shooting conditions and routine cleaning, I anticipate these pins will remain functional for the lifespan of the sight itself.

Maintenance is exceptionally low. A light application of gun oil during regular firearm cleaning is sufficient to keep the steel protected and the mechanism operating smoothly. There are no complex parts to clean or special procedures required. Potential failure points would likely stem from improper installation – forcing the pins or damaging the threads if applicable – rather than material failure.

Accessories and Customization Options

The primary “accessory” included with the Kensight Colt Style Formerly Accro Hinge Pin is the inclusion of two different pin types: a Spirol roll pin and a solid pin. This dual offering is a smart move, providing options for users who might have a preference or specific requirement for one type over the other.

Beyond this, there are no other accessories. These hinge pins are designed to integrate directly into existing Kensight or compatible Colt Style/Elliason rear sights. Their purpose is to be a direct replacement part, and they fulfill that role without needing additional components.
