Built for the modern legally armed citizen, FN developed this platform to meet today's challenges. It's a low profile easy to carry personal protection gun with the precision performance of a competition target pistol. The 509 Compact MRD features the FN Low Profile Optics Mounting System that is compatible with most of the popular micro red dot pistol optics on the market today. For a perfect co-witness with your optic the sights are built to the right height. The 509 Compact MRD has fully ambidextrous controls, a load chamber indicator, enhanced front/rear cocking serrations and no safety to get in the way. The ergonomic polymer frame is resilient enough to stand up to the worst conditions and interchangeable back straps ensure the perfect fit for a positive grip. The FN-509 Compact MRD represents the next generation of FNH handguns, for those that refuse to accept 'second best' when it comes to self defense.
