In the world of firearm maintenance and customization, sometimes the simplest components make the most significant difference. The Glock 6.1MM Fixed Rear Steel Sight, Not G42/G43 is one such part; it’s an OEM replacement rear sight designed for a wide range of Glock pistols, specifically excluding the G42 and G43 models. Its unassuming nature belies its importance for maintaining a reliable sight picture. I came to need this specific sight after a training session where one of my older Glock sights took an unexpected tumble onto concrete.
While I had considered aftermarket fiber-optic sights for a speedier sight acquisition, the rugged environment of the range, coupled with the need for absolute reliability over flash, steered me back toward a more traditional, robust option. The allure of a factory Glock part, known for its no-nonsense durability, was strong. My first impression upon receiving this steel sight was its solid, no-frills construction.

Real-World Testing: Putting Glock 6.1MM Fixed Rear Steel Sight, Not G42/G43 to the Test
First Use Experience
My initial test for this Glock 6.1MM Fixed Rear Steel Sight, Not G42/G43 was at my local indoor shooting range, a familiar environment for me. I installed it on a Glock 19 that had been experiencing some minor accuracy issues after a previous sight became loose. The installation process itself was straightforward, requiring standard Glock sight tools.
The sight performed admirably under typical range conditions, including repeated firing over an hour-long session. It maintained its position and provided a consistent sight picture with every draw and fire. There were no surprises or quirks to report; it simply did its job as expected, proving to be an intuitive and immediate replacement.
Extended Use & Reliability
Over the subsequent months, this fixed rear sight has seen consistent use on my range pistol, experiencing everything from dusty outdoor shooting days to being stored in a climate-controlled gun safe. It has held up remarkably well, showing no signs of degradation or performance drop. Cleaning and maintenance are as simple as wiping it down with a solvent-dampened cloth, a task that takes mere seconds.
Compared to some budget aftermarket sights I’ve used in the past, which often loosen or develop play after heavy use, this Glock steel sight feels significantly more reliable. It’s a testament to the straightforward design and quality of materials used by Glock. The inherent simplicity of a fixed steel sight, devoid of complex adjustments or fragile components, means it’s built for the long haul.
Breaking Down the Features of Glock 6.1MM Fixed Rear Steel Sight, Not G42/G43
Specifications
The Glock 6.1MM Fixed Rear Steel Sight, Not G42/G43 is an OEM part, indicating it’s manufactured to the same standards as the sights originally installed on many Glock firearms. The key specification here is its 6.1mm width, a standard measurement for rear sights on many Glock models. This specific dimension is crucial for proper alignment with the front sight, ensuring an accurate sight radius.
It’s constructed from steel, which provides a significantly higher degree of durability compared to polymer sights. This steel construction means it’s far more resistant to impacts and environmental damage. The sight is finished in a standard black color, offering a non-glare surface essential for quick target acquisition.
It is important to note that this particular sight is not compatible with the Glock 42 or 43 models, which utilize different sight dimensions. This is a fixed rear sight, meaning it does not offer windage or elevation adjustments beyond what is inherent in the sight’s design and its pairing with a compatible front sight. Its intended purpose is straightforward: provide a robust and reliable rear sight channel.
Performance & Functionality
The primary job of any rear sight is to provide a clear and stable reference point for aiming. This Glock 6.1MM Fixed Rear Steel Sight, Not G42/G43 excels at this fundamental task. When paired with a correctly aligned front sight, it offers a crisp sight picture that is easy to acquire, even under stress or in suboptimal lighting conditions.
Its strength lies in its absolute reliability and durability. Unlike adjustable sights that can shift or polymer sights that can deform, this steel unit remains steadfast. The main weakness, if one can call it that, is its lack of adjustability; it’s a fixed sight that relies on the correct front sight height and proper installation for accurate point-of-aim/point-of-impact. It meets expectations for a factory replacement part, offering dependable performance without any frills.
Design & Ergonomics
The design of this rear sight is characteristically Glock: utilitarian, robust, and functional. The black, non-reflective finish minimizes glare, which is crucial for maintaining focus on the front sight and the target. Its steel construction provides a reassuring weight and a feel of solid engineering.
Ergonomically, it’s designed to integrate seamlessly with the slide of a Glock pistol. There are no sharp edges or protruding parts that would snag on a holster or clothing. The rear face of the sight is typically serrated to further reduce glare, and the notch is well-defined, providing a clear sight channel. Its simple, fixed design means there’s virtually no learning curve; it’s ready to go from the moment it’s properly installed.
Durability & Maintenance
Given its steel construction, the durability of this Glock rear sight is exceptional for its class. Under normal use – which for a firearm sight could mean thousands of rounds and regular handling – it’s highly unlikely to fail. It’s resistant to cracks, chips, and deformation that can plague less robust materials.
Maintenance is minimal to non-existent. A quick wipe-down during firearm cleaning is all that’s needed to keep it free of debris and oil. There are no moving parts to maintain or lubricate. The primary concern would be the integrity of the dovetail cut on the slide and the retaining screw or drift pin used for installation; the sight itself is built to endure.
Accessories and Customization Options
As an OEM replacement part, this Glock 6.1MM Fixed Rear Steel Sight, Not G42/G43 does not typically come with accessories. Its function is standalone, intended to be installed directly onto the slide. However, its compatibility with standard Glock sight tools is a given.
If customization is desired, the user would typically pair this rear sight with a compatible Glock front sight of the appropriate height to achieve the desired sight radius and point of impact. While this is a fixed rear sight, the choice of front sight height becomes the primary method for zeroing the firearm. It’s also worth noting that other manufacturers produce front sights designed to work with Glock’s rear sight dovetail, allowing for some degree of customization in front sight style and material.
