FN 509 is a rugged and dependable semi-automatic 9mm pistol well equipped for self-defense and tactical applications. This Certified Used example features a flat black finish and ships with two 15-round magazines, the original soft case, box, manual, and an additional backstrap—offering value and readiness right away.

Overview: What the FN 509 Brings to the Table

Built on a polymer frame with proven FN engineering, the FN 509 was designed for the demands of modern defensive use. The key selling points of this specific offering are its flat black finish for low-reflectivity concealment, two factory 15-round magazines for ample capacity, and the inclusion of accessories that many used listings skip: soft case, original packaging, manual, and an extra backstrap to tweak grip fit.

Included Items and Why They Matter

When you buy this Certified Used FN 509, you’re not just getting a pistol — you’re getting a ready-to-shoot package. Two 15-round magazines mean you can train and carry without immediately investing in add-ons. The original soft case and box make storage and transport easier, while the manual is essential for safe operation and maintenance. The additional backstrap allows shooters of different hand sizes to tailor the grip angle and control, improving pointability and recoil management.

Fit, Ergonomics, and Controls

The FN 509’s grip geometry is designed to deliver a consistent point of aim and predictable recoil impulse. With the included extra backstrap, you can dial in palm support and trigger reach. Controls are positioned for practical, rapid manipulation by right- or left-handed operators. The flat black finish minimizes glare in low-light scenarios and adds a durable protective surface that stands up to daily carry and range use.

Practical Notes from the Range

From a tactical perspective, two 15-round magazines provide a baseline for both training and duty use. That level of capacity allows for meaningful practice drills — controlled pairs, failure drills, and reload practice — without constant magazine changes. The soft case and manual help maintain the gun between sessions, and the Certified Used inspection ensures you’re not getting an item with hidden wear or mechanical issues.

Why Certified Used Makes Sense Here

Certified Used firearms can deliver excellent value when vetted properly. This FN 509 carries the Certified Used stamp, which indicates the pistol was inspected and evaluated to be in very good to excellent condition. The listing explicitly includes a ‘no questions asked’ return policy, which reduces risk on the buyer’s part. For tactical-minded buyers, that combination of savings and assurance is particularly attractive.

Price and Value Considerations

At the listed price of $455.99, this FN 509 represents a competitive entry point into a quality defensive platform. The price reflects not just the pistol itself but the included accessories and the Certified Used status—items like two magazines and an extra backstrap typically add cost if purchased separately. For budget-conscious buyers who still require a credible defensive firearm, this configuration is worth assessing. View product details and pricing to confirm availability and specifics.

Maintenance and Long-Term Considerations

FN pistols are known for straightforward field stripping and reliable parts availability. Even though this listing doesn’t specify a detailed parts breakdown or caliber specifics beyond being a 9mm semi-auto platform, standard maintenance — cleaning the bore, inspecting the recoil spring, and keeping contact surfaces lightly lubricated — will preserve function and extend service life. The included manual should be your primary reference for disassembly and torque/spec guidance.

Accessories and Upgrades

Given the base package, the next logical upgrades for many owners are optic-ready slides (if you desire a red dot), upgraded night sights, or an extended magazine for training. Because the listing includes two factory magazines, you can prioritize upgrades that directly impact performance, like sighting systems or holsters matched to the flat black finish and the pistol’s concealability profile.
