About This Firearm
The FN 509 Compact is a compact striker-fired 9mm built for concealed carry and duty use. It has an MSRP of $639, and it is the cut-down version of FN's Modular Handgun System entry, keeping the same cold hammer-forged stainless barrel and ambidextrous controls in a 6.8-inch frame.
A flush 12-round magazine and a 15-round magazine both come in the box, with two interchangeable backstraps, a soft case and a lock, and FN lists the pistol as taking its full-size 509 magazines once the right sleeve is fitted. The front sight is a low-profile high-visibility dot and the rest of the sight set is shaped to be snag-free. There is no optic cut on this version, and the trigger is a flatter-faced design FN gives as a 5.5 to 7.7 lb range. At 25.5 oz it is heavy for a pistol this size.
If you're cross-shopping, the FN 509 Compact Tactical is this pistol with a dot mount and a threaded 4.32-inch barrel, 26.2 oz for an MSRP of $914. A Springfield Armory Hellcat Pro OSP holds three more rounds at 21.0 oz with a factory optic cut and the same 3.7-inch barrel, at an MSRP of $670, and it is 4.5 oz lighter than the FN.

Strengths & Limitations
- The barrel is cold hammer-forged stainless with a recessed target crown and a polished chamber and feed ramp.
- Aggressive 509 slide serrations run front and rear, so the slide can be worked with wet or gloved hands.
- The grip texture is enhanced over the original 509 pattern and the backstraps swap, so the same pistol fits a range of hands.
- There is no optic cut on this version, so running a dot means the Compact Tactical or a milled slide.
- The 15-round magazine in the box stands proud of the grip, so the spare magazine does not sit flush.
- FN gives the trigger as a 5.5 to 7.7 lb range, so two pistols off the same shelf can break differently.

Frequently Asked Questions
Is there an optics-ready 509 Compact?
Yes, as a separate pistol. FN sells the 509 Compact MRD with a cut slide and lists it as a related product on this pistol's page.
How does it differ from the full-size FN 509?
The grip and the barrel are both shorter, 3.7 inches of barrel against 4.0, and the flush magazine holds 12 where the full-size holds 17.
What treatment is on the slide?
Ferritic nitrocarburizing, which FN uses across the 509 line. It hardens the surface of the stainless slide.
Where is it made?
The United States.
