First Impressions of Shield Sights FN 509 Optics Ready Low Pofile Slide Mount
The Shield Sights FN 509 Optics Ready Low Profile Slide Mount promises a streamlined and secure platform for mounting red dot optics on the ever-popular FN 509 pistol. As someone who has spent countless hours tweaking and modifying firearms for optimal performance, I was eager to see if this mount lived up to the hype, especially given the competitive price point of $55.99.
I was in search of a lower profile mounting solution for my FN 509 Tactical. The factory setup felt a little too high, making it challenging to co-witness with the suppressor-height sights.
Upon unboxing, I was immediately struck by the mount’s minimalist design. It is crafted from polymer and boasts a sleek, black finish. The build quality initially felt robust for a polymer piece, though long-term durability was a question mark, especially compared to aluminum alternatives that tend to be more rugged. Compared to some other mounts on the market, particularly those made of steel, the Shield Sights mount stood out due to its potential for reduced weight and impact on the pistol’s balance. Ultimately, I chose this option, hoping its low profile would improve my sight picture and overall shooting experience. My first impression was cautiously optimistic – the design seemed promising, but the polymer construction gave me some reservations.
Real-World Testing: Putting Shield Sights FN 509 Optics Ready Low Pofile Slide Mount to the Test
First Use Experience
I first tested the Shield Sights FN 509 Optics Ready Low Profile Slide Mount at my local shooting range. I primarily focused on drills that required rapid target acquisition and transitions.
The initial performance was promising, especially considering the low profile design that facilitated quicker target acquisition. One minor issue arose; the polymer mount felt less secure than a metal one. It felt like the screws needed tightening more often than a metal counterpart.
Extended Use & Reliability
After several range sessions and approximately 500 rounds fired with the Shield Sights mount, I began to form a more comprehensive opinion. There was noticeable wear on the polymer material, especially around the screw holes.
The mount maintained its zero adequately, though I found myself checking the screw torque more frequently than I would with a metal mount. Cleaning was simple enough, but I took extra care not to use harsh solvents that could potentially degrade the polymer. Compared to a previous steel mount I used on another pistol, this one felt significantly less durable. It reinforced the understanding that polymer mounts prioritize weight savings over maximum longevity.
Breaking Down the Features of Shield Sights FN 509 Optics Ready Low Pofile Slide Mount
Specifications
The Shield Sights FN 509 Optics Ready Low Profile Slide Mount is specifically designed for the FN 509 Optics Ready pistol and intended for use with red dot sights utilizing the RMS/SMS footprint. It is constructed from black polymer.
The mount features an optic cut compatible with the Holosun 509T, and is made by Shield Sights. This specific design makes the Shield Sights mount an ideal option for someone seeking a lightweight, low-profile optic solution that will not add excessive weight to their pistol, at a budget-friendly price.
Performance & Functionality
The mount’s primary function is to provide a stable and low-profile platform for mounting a red dot optic. In this capacity, it performs reasonably well.
The low profile enhances sight picture, especially when co-witnessing with iron sights. However, the polymer construction is a definite weakness that could potentially lead to issues over time. It met initial expectations, but I question its long-term durability.
Design & Ergonomics
The black polymer provides a clean aesthetic and helps minimize added weight. The mount is fairly easy to install, even for someone with minimal gunsmithing experience.
The low-profile design is a major selling point. It contributes to improved ergonomics and a more natural shooting stance.
Durability & Maintenance
Given its polymer construction, the mount’s long-term durability is questionable. Regular cleaning is required to prevent any potential corrosion around the mounting screws.
The ease of maintenance is offset by the concern about potential wear and tear. The mount needs to be routinely inspected for signs of cracking or deformation.
Accessories and Customization Options
The Shield Sights FN 509 Optics Ready Low Profile Slide Mount doesn’t come with any additional accessories beyond the mounting screws. Its primary purpose is to facilitate the attachment of a red dot sight.
Compatibility is limited to red dots with the RMS/SMS footprint and the Holosun 509T. This limits customization options to optics within that specific standard, though there are several red dot sights on the market that fit those parameters.
