FN 509

Overview: why this FN 509 package stands out

The FN platform has long been respected for duty-grade reliability and conservative ergonomics, and this FN 509 configuration leans into that heritage while adding modern performance features. This Certified Used offering is equipped with a Leupold DeltaPoint Pro 2.5 MOA optic installed, giving fast target acquisition and precise point-of-aim for both close-quarters work and more deliberate shots.

What’s included — the gear that matters

Specific contents are where this listing provides real value. Included with the FN 509 are:

• One extended 24-round magazine — ideal for range sessions or defensive scenarios where extra capacity reduces reload frequency.
• One 15-round magazine plus three 12-round magazines — flexibility for local capacity laws or carry preferences.
• Original box and soft case — secure storage and transport without immediately needing additional gear.
• Owner’s manual — important for safe operation, maintenance guidance, and understanding the platform.
• Two extra MRD plates and an extra recoil spring — practical spares that keep your red dot mounting options open and help manage recoil tuning over time.

These inclusions make this certified used purchase more turnkey than many other secondhand listings.

Optic: Leupold DeltaPoint Pro 2.5 MOA

The installed Leupold DeltaPoint Pro 2.5 MOA optic is a high-quality miniature red dot that many professionals and competition shooters trust. A 2.5 MOA dot balances fine precision with quick sighting — ideal for defensive engagements where a tight center hold matters but speed cannot be sacrificed. Leupold’s reputation for durable optics means the DeltaPoint Pro complements the FN 509’s service-oriented design.

Why the optic matters with this package

Having an MRD-ready slide and the included plates means you can maintain co-witness setups, try different mounting heights, and fine-tune your cheek weld and sight picture without additional purchases. The included extra MRD plates let you experiment with plate compatibility or swap to other optics if your mission or preference changes.

Ergonomics, capacity, and handling

The FN 509 platform blends a grip angle and ergonomics familiar to many shooters, with textured surfaces and an interface that supports rapid, repeatable presentations. The magazine mix in this package gives you options for training and practical carry: the 24-round extended magazine is excellent for extended drills at the range, while the 15- and 12-round magazines are useful for range rotation or complying with jurisdictional limits.

Practical use cases

This FN 509 package is well-suited for:

• Range-focused shooters who want a high-capacity semi-auto paired with a quality reflex optic.
• Civilians seeking a reliable home-defense pistol with optics and extra magazines for immediate use and training.
• Collectors and pragmatic buyers who prefer Certified Used firearms that include spare parts and factory-level accessories.

Range performance and maintenance notes

Expect the FN 509 to run reliably with standard defensive and range ammunition when properly maintained. The included extra recoil spring is a practical touch — it lets you return the pistol to factory-tension specs after extended firing or testing heavier handloads. Routine cleaning, proper lubrication, and running break-in ammunition cycles are advisable to ensure the Leupold optic and the pistol’s serrations and controls remain crisp and functional.

Final considerations before you buy

For those seeking a ready-to-go package, the FN 509 with Leupold DeltaPoint Pro, a 24-round extended magazine, multiple backup magazines, and practical spares represents excellent immediate utility out of the case. The price of $854.99 reflects that bundled value and the peace-of-mind that comes with a Certified Used designation and return policy.
