FN 509 Semi Auto: Tactical Firearm with Extended Mags

Precision, durability, and practical capacity make a defensive semi-automatic pistol a go-to for professionals and serious enthusiasts. As operators who value reliable function under pressure, we look for pistols that combine solid ergonomics, proven controls, and a magazine package that supports extended training and duty use.

FN 509 arrives configured for immediate, flexible use: three extended 24-round magazines, one 15-round magazine, one 12-round magazine, the original box, owner’s manual, and an extra backstrap. This offering is listed as a Certified Used firearm, which means it’s held to a very good to excellent condition standard and backed by a ‘no questions asked’ return policy — all for a listed price of $569.99.

Why the FN 509 is a strong choice for defensive use

As seasoned operators, we respect platform designs that balance robustness with controllability. The FN 509 has earned a reputation as a duty-caliber offering from Fn that emphasizes hard use reliability. This particular Certified Used example stands out because of the included magazine complement and the extra backstrap, which adds fit options for different hand sizes. For a Semi Auto category firearm, the FN 509 delivers the ergonomic and mechanical consistency you want for both range work and a duty application.

Magazine configuration and tactical utility

The bundled magazines are the headline feature for anyone who trains frequently or wants immediate extended-capacity capability. Three extended 24-round magazines paired with a 15-round and a 12-round magazine offer versatility:

• Three 24-rounders provide high-capacity options for extended drills, plate racks, or duty use.
• The 15-round magazine is useful for states or ranges with capacity limits while keeping an extra full-length magazine available.
• The 12-round magazine is compact for transport or practice when reduced capacity is preferred.

Having multiple magazines of different capacities included in the package reduces immediate accessory purchases and lets you tailor reload drills and carry choices from day one. If you want to confirm current stock or make the purchase, View product details and pricing.

Certified Used: quality assurance and value

Buying a Certified Used firearm can be a smart way to access high-value equipment without paying full retail. This FN 509 listing includes the original box and owner’s manual — small details that matter when evaluating condition and provenance. The Certified Used stamp indicates the firearm has been inspected and is in very good to excellent condition, and the retailer’s ‘no questions asked’ return policy reduces risk if the piece doesn’t meet expectations. At a price of $569.99, this package represents a compelling value when you factor in the magazine bundle and included accessories.

Ergonomics, handling, and the extra backstrap

Fit is crucial; the extra backstrap included with this FN 509 allows shooters to dial in grip feel for consistent trigger reach and control. That matters for follow-up shots and sustained accuracy. As operators, we focus on a neutral grip angle, a positive tactile interface with controls, and a clean trigger break — all areas where the FN 509 platform performs well in the hands of experienced shooters. The ability to change backstraps means this Certified Used gun can adapt to different hand sizes without needing immediate aftermarket modifications.

Maintenance, accessories, and practical tips

When you bring a Certified Used FN 509 into your kit, start with a full inspection and function check. Ensure the included magazines feed, lock up, and index properly. Clean the bore and action, lubricate to spec, and cycle dummy rounds to verify smooth operation. The original owner’s manual included in this package is handy for maintenance intervals, torque specs, and recommended lubrication points.

Recommended accessories

• A quality holster that fits the FN 509 profile and supports the magazine footprint when carrying extended mags.
• Spare magazines (even though this package already includes five) to expand training rounds between reloads.
• Night sights or optics-ready mounting solutions if operational use requires rapid target acquisition in low light.
