Shield Sights FN Five-seveN Polymer Slide Mount Review

First Impressions of Shield Sights FN Five-seveN Polymer Slide Mount

The Shield Sights FN Five-seveN Polymer Slide Mount promises a simple, effective way to add a red dot sight to one of the more unique handguns on the market. The FN Five-seveN, chambered in the high-velocity 5.7x28mm, is known for its accuracy and flat-shooting characteristics, but its polymer slide presents a challenge for traditional optic mounting. This mount aims to solve that problem, providing a stable platform without requiring extensive gunsmithing.

I was drawn to the Shield Sights FN Five-seveN Polymer Slide Mount because I wanted to explore the potential of the Five-seveN as a precision pistol. I had always struggled with the factory iron sights and desired a quicker, more intuitive aiming system. This mount promised a straightforward solution, unlike some other options that involved slide milling or more complex installation procedures.

Upon unboxing, my first impression was that the mount was surprisingly lightweight. The polymer construction seemed robust, although I initially had reservations about its long-term durability compared to metal alternatives. The black finish was clean and matched the aesthetics of the Five-seveN well.

Compared to universal optic mounts I’ve used on other handguns, this Shield Sights mount felt more purpose-built and less like a one-size-fits-all solution. The Trijicon RMR mount was another contender, but I chose this for its lower profile and reported ease of installation. I was cautiously optimistic about the product, hoping it would live up to its promises of simple installation and reliable performance.
