FN 509 Tactical Review: The Best Optics Ready Pistol?

Published on February 14, 2019
Duration: 22:18

This guide details the process of mounting optics onto the FN 509 Tactical pistol, emphasizing its proprietary optics mounting system. The system utilizes interchangeable inserts that mount directly to the frame, acting as a recoil lug. The review highlights that while the Leupold DeltaPoint Pro mounts directly, other optics like the RMR require an adapter plate. The importance of using Loctite and the functionality of the rear cover plate for one-handed manipulations are also covered.

Quick Summary

The FN 509 Tactical boasts a superior factory optics mounting system where inserts mount directly to the frame, acting as a recoil lug. This robust design enhances reliability during one-handed manipulations and minimizes potential loosening compared to plate-based systems. It also includes two recoil springs for suppressed use and excellent tritium night sights for co-witnessing.

Frequently Asked Questions

What makes the FN 509 Tactical's optics mounting system stand out?

The FN 509 Tactical features a proprietary optics mounting system where inserts mount directly to the frame, acting as a recoil lug. This design is praised for its robustness, reducing the likelihood of components shearing off during one-handed manipulations and minimizing parts that can loosen compared to plate-based systems.

Does the FN 509 Tactical come with different recoil springs?

Yes, the FN 509 Tactical includes two recoil springs: a 17-pound spring and a 22-pound spring. The heavier 22-pound spring is generally recommended for suppressed use to enhance reliability, although it may occasionally prevent the slide from locking back on the last round.

What are the key features of the FN 509 Tactical's factory sights?

The FN 509 Tactical is equipped with tritium night sights. The rear sight is subdued with serrations, while the front sight features a bright white ring. This design facilitates easy distinction between sights in various lighting conditions and allows for co-witnessing with mounted optics.

Are there any common issues with the FN 509 Tactical's controls?

The ambidextrous magazine release has been noted as a potential point of concern. It can be inadvertently activated, particularly when using larger capacity magazines, which may lead to the magazine dropping during firing. The slide lock, however, is well-protected and less prone to accidental actuation.
