What you get: Certified Used and included accessories
This FN 509 arrives as a Certified Used firearm, which matters. The Certified Used stamp indicates the pistol was inspected and is in very good to excellent condition and is held to a high quality standard. Each Certified Used firearm from the seller includes a straightforward ‘no questions asked’ return policy, giving buyers added peace of mind when purchasing a used pistol.
Included items: one 17-round magazine, extra backstraps to tailor the grip to your hand, and a soft case for transport and storage. That combination makes it an immediately practical package for range sessions, training, and home defense preparation. The asking price of $569.99 represents a strong value considering the sights, ambidextrous controls, and certification standard.
Sights and low-light readiness
One of the first things you’ll notice about this FN 509 is the sighting package: a Tritium rear night sight paired with a Hi-Viz Tritium front sight. Tritium inserts provide passive illumination without batteries, delivering quick target acquisition when ambient light drops. The Hi-Viz front gives a bright focal point while the Tritium rear aids alignment in darker conditions.
For defensive scenarios or low-light training, factory-installed tritium sights are a meaningful upgrade over standard white-dot sights. They reduce the need for aftermarket modifications and keep the pistol ready from the moment you pick it up.
Controls and ergonomics for real-world use
Ambidextrous controls are no longer a luxury—they’re practical. This FN 509 features both an ambidextrous magazine release and an ambidextrous slide release. Those elements make reloads and manipulations more intuitive for left- and right-handed shooters, and they provide redundancy for shooters who like multiple control options during drills.
Ergonomically, the included extra backstraps allow you to tune hand fit and recoil bite. Combine that with a 17-round magazine and you’ve got a platform that balances capacity with manageable handling for follow-up shots and high-round training sessions.
Why ambidextrous controls matter
Ambidextrous mag and slide releases reduce friction when learning transitions, working from weak-hand positions, or when clearing malfunctions under stress. These controls shorten training curves and make the pistol more accessible to a broader range of shooters.
Performance, reliability, and maintenance
While this listing doesn’t specify caliber on the product sheet, the FN 509 line is known for robust reliability across its offered chamberings. Certified Used inspection ensures that the pistol’s cycling, lockup, and safety systems meet a high standard before it reaches your hands. Routine maintenance—field-strip cleaning, lubrication of the slide rails, and periodic inspection of springs and sights—will keep this pistol functioning for years of training.
For buyers concerned with longevity and function, the Certified Used designation coupled with the included return policy reduces risk and supports an informed purchase. View product details and pricing on the shop page to confirm inventory and current condition.

Training and carry considerations
Whether you plan to keep this FN 509 as a range pistol or a backup carry option, training is key. Start with fundamentals: draw and presentation, sight alignment with the tritium set, and reloads using the included 17-round magazine. Practice low-light exercises to learn how the Tritium front and rear work in different lighting conditions.
Storage and safety are central—use a quality lockable storage solution and keep ammunition stored separately if minors or guests are in the home. Regular range time paired with dry-fire practice will familiarize you with the ambidextrous controls and the ergonomics tailored by the extra backstraps.
Why this FN 509 stands out
This Certified Used FN 509 offers a compelling mix of practical features: night-capable Tritium sights, ambidextrous controls, a 17-round magazine, and customizable grip via extra backstraps—all for $569.99. The Certified Used designation and return policy remove much of the uncertainty buyers often face with pre-owned firearms. For shooters who want a proven semi-auto platform with duty-style controls and immediate low-light capability, this offering is a smart, budget-conscious choice.
