First Thoughts on the C&H Precision Weapons V4 MIL/LEO Adapter Holosun 509T for Glock MOS
Optics on pistols, especially red dots, have become increasingly common, almost essential in certain circles. But mounting them on Glock MOS pistols hasn’t always been the cleanest affair. Enter the C&H Precision Weapons V4 MIL/LEO Adapter Holosun 509T for Glock MOS, a plate designed to provide a secure and low-profile mounting solution for the popular Holosun 509T red dot sight.
I’ve been running red dots on my pistols for years, mostly for faster target acquisition and improved accuracy, especially in dynamic shooting scenarios. The factory Glock MOS system is…okay, but it can feel a bit clunky, and I’ve always been on the lookout for a more refined solution.
Upon unboxing, the adapter plate feels solid and well-made. The black MIL-SPEC Type III Hard Anodized finish gives it a professional and durable appearance. It’s lightweight, but reassuringly robust, hinting at a quality build.
Compared to some other adapter plates I’ve used, the C&H Precision Weapons offering looks significantly thinner. This suggests a lower profile setup, which is always desirable for a pistol optic. It also appeared to be much more streamlined that other plates such as the Strike Industries or Forward Controls Designs offerings. My initial excitement stemmed from the promise of a cleaner, more reliable, and less bulky way to mount my 509T.
Real-World Testing: Putting C&H Precision Weapons V4 MIL/LEO Adapter Holosun 509T for Glock MOS to the Test
First Use Experience
I tested the C&H Precision Weapons V4 MIL/LEO Adapter Holosun 509T for Glock MOS primarily at my local shooting range. I ran it on my Glock 19 MOS, cycling through a variety of drills involving rapid target acquisition, transitions, and distance shooting. The weather was typical for my area – a mix of sun and intermittent light rain.
Installation was straightforward, with the provided screws fitting perfectly and the plate sitting flush on the slide. The Holosun 509T mounted securely, with no noticeable wobble or play. During live fire, the plate held up extremely well, maintaining zero throughout several hundred rounds.
Extended Use & Reliability
After several months of consistent use, the C&H Precision Weapons V4 MIL/LEO Adapter Holosun 509T for Glock MOS has proven to be exceptionally reliable. There are no signs of loosening or shifting, even after extended training sessions and hundreds upon hundreds of rounds. The C&H Precision Weapons plate has been rock solid.
The hard anodized finish has held up admirably to holster wear and general handling. Cleaning is a breeze, requiring only a quick wipe-down with a solvent-dampened cloth. It far outperforms the factory MOS plates.
Breaking Down the Features of C&H Precision Weapons V4 MIL/LEO Adapter Holosun 509T for Glock MOS
Specifications
- Material: 6061 Aluminum, offering a good balance of strength and weight. This ensures the plate can withstand the stresses of repeated firing without adding unnecessary bulk to the pistol.
- Mounting Hardware: Stainless Steel, chosen for its corrosion resistance and durability. This is crucial for maintaining a secure and reliable optic mounting, even in harsh environments.
- Thickness: 0.095″ to 0.099″, an incredibly thin profile. This is a huge advantage, as it minimizes the height-over-bore of the optic, making for a more natural and intuitive shooting experience.
- Finish: Black MIL-SPEC Type III Hard Anodized, providing excellent wear and corrosion resistance. The black finish also blends seamlessly with most Glock slides.
- Compatibility: Designed specifically for Glock MOS models (G17, G19, G22, G23, G34, G35, G40, G41, G45, G47) and the Holosun 509T red dot sight. It’s crucial to note that it WILL NOT work with the Holosun HE509-RD ACSS Vulcan.
Performance & Functionality
The C&H Precision Weapons V4 MIL/LEO Adapter Holosun 509T for Glock MOS excels at its primary function: providing a secure and stable mounting platform for the Holosun 509T. The low profile design is a significant advantage, allowing for a more natural sight picture and faster target acquisition. It greatly improves the user experience.
The precise machining and tight tolerances ensure a snug fit, eliminating any unwanted movement or vibration. The included stainless steel screws provide ample clamping force, keeping the optic firmly in place even under heavy recoil. No issues or failures were noted at all.
Design & Ergonomics
The adapter plate boasts a simple, yet effective design. The low profile is a standout feature, as it keeps the red dot close to the bore axis, minimizing parallax and improving shooting comfort. The black anodized finish blends seamlessly with the Glock slide, giving it a factory-like appearance.
Installation is relatively straightforward, requiring only basic tools and a few minutes of time. The included screws are of high quality and properly sized, ensuring a secure and hassle-free mounting process. No specialized tools are needed to do so.
Durability & Maintenance
The C&H Precision Weapons V4 MIL/LEO Adapter Holosun 509T for Glock MOS is built to last. The 6061 aluminum construction and hard anodized finish provide excellent resistance to wear, corrosion, and impact. The plate has held up exceptionally well to daily use and exposure to various environmental conditions.
Maintenance is minimal, requiring only occasional cleaning with a mild solvent and a soft cloth. The stainless steel screws are also corrosion-resistant, ensuring long-lasting performance even in humid environments. It’s as simple as it gets!
Accessories and Customization Options
The adapter plate comes with everything needed for a basic installation: the plate itself and two M3 mounting screws. There aren’t any other included accessories. However, the primary customization option lies in the choice of optic, specifically the Holosun 509T, which offers a variety of reticle options and brightness settings.
While the C&H Precision Weapons adapter is designed specifically for the 509T, the Glock MOS system itself allows for a wide range of aftermarket slide modifications and accessory attachments. You could change the trigger or guide rod if desired.
