Frequently Asked Questions
FN 509 compact for sale
How much is a FN 509 compact worth?
FN 509 Compact pistols have an MSRP of $639, though current retail prices can drop significantly lower, with sale prices seen below $500. Price varies based on configuration, sights, and tactical features. Used models may sell for less depending on condition.
Is the FN 509 compact a good gun?
The FN 509 Compact is a reliable, accurate pistol well-suited for concealed carry. It holds 15-17 rounds in a compact frame and is easy to maintain. Most users report consistent performance. Whether it fits you depends on hand size, budget, and personal shooting preferences.
What are the common problems with the FN 509 compact?
Reported issues include trigger stiffness, occasional failure to feed, slide stop malfunctions, and erratic ejections. Some users experienced stovepipes or slide lock failures. Striker durability concerns arose with repeated dry firing. Many problems resolved after proper break-in, cleaning, lubrication, and using quality ammunition. FN offers warranty support for defects.
Is the FN 509 drop safe?
The FN 509 is drop safe. It includes a passive firing pin safety that blocks the firing pin from moving forward unless the trigger is deliberately pulled, preventing accidental discharge if the pistol is dropped.
Is FN 509 good for concealed carry?
Yes. The FN 509 comes in compact and midsize variants holding 15–17 rounds of 9mm. Its striker-fired design, reliable performance, and ergonomic controls suit defensive carry well. The Compact model is slimmer for easier concealment. Choose based on hand size and holster availability.
What does mrd mean in 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 additional adapters or machining.
What is the difference between 509 and 509 MRD?
The 509 is a full-size duty pistol with a 17-round capacity. The 509 MRD designation applies across multiple variants — including Compact, Midsize, and Fullsize — each with an optics-ready slide for mini red dots. The Compact MRD, for example, has a shorter frame and different magazine capacity than the full-size 509.
What magazines are compatible with FN 509?
Factory FN 509 magazines work across all 509 variants—Compact, Midsize, Full-size, Tactical, LS Edge, and CC Edge—as long as capacity and frame size match. Standard options include 17-round magazines, with a 24-round option available for increased capacity.
