Frequently Asked Questions
FN 509 for sale
Is the FN 509 a good gun?
Whether the FN 509 is good depends on your needs. It's a reliable striker-fired 9mm available in full-size, compact, and midsize frames, suited for carry, duty, or home defense. Most shooters praise its ergonomics and durability. Street prices typically range from $600 to $850 depending on variant and retailer.
What is the difference between 509 and 509 tactical?
The 509 Tactical adds a threaded barrel for suppressor use, an optics-ready slide, and ergonomic frame improvements compared to the standard 509. Both are full-size, striker-fired 9mm pistols sharing the same basic platform, but the Tactical is specifically configured for suppressed or duty-enhanced applications.
How much is a FN 509 compact worth?
FN 509 Compact pistols typically sell for around $834, with most listings ranging from $550 to $1,399 depending on configuration. Optics-ready or tactical variants cost more. Current data shows 71 in-stock compact variants across 43 retailers.
What are the common problems with the FN 509 compact?
Reported issues include failure to feed, failure to eject, and slide lock malfunctions, particularly in early rounds. Some users report trigger stiffness and magazine release problems. Striker durability concerns exist with repeated dry firing without snap caps. Many issues resolve after cleaning and a proper break-in period with quality ammunition.
Is the FN 509 drop safe?
Yes. The FN 509 passed U.S. Army drop safety testing and includes a trigger safety, firing pin block, and out-of-battery safety. These passive safeties prevent discharge if the pistol is dropped. Always use a quality holster and follow safe handling practices.
Is FN 509 good for concealed carry?
Yes. FN offers compact and midsize 509 variants designed for concealed carry. Striker-fired, reliable, and ergonomic, they suit defensive use well. Compact models weigh under 27 ounces and are comfortable to carry and shoot accurately.
What does mrd mean on FN 509?
MRD stands for Mini Red Dot. FN 509 models with this designation have an optics-ready slide that accepts miniature red dot sights directly, without aftermarket adapters, making them suitable for optics-equipped carry or duty use.
Do police use FN 509?
Yes. The Los Angeles Police Department selected the FN 509 MRD-LE as their duty pistol after it passed a 20,000-round endurance test. The MRD-LE variant features key fire control upgrades and exclusive enhancements designed for law enforcement use, delivering accuracy suited to duty applications.
