FN Tactical 509 Description
The FN 509 Tactical is an extension of the FN 509 family of pistols; it is based on FN’s submission pistol which the U.S. Army tested for its Modular Handgun Trials, but boasts the significant improvements to the design that were implemented in the 509.
One of the most prominent features of this pistol is FN America’s Low-Profile Optics Mounting System (U.S Patent No. 10/352,654); this makes the tactical FN 509 platform not only compatible with over ten commercially-available, miniature red dot (MRD) optics that co-witness with the factory-installed suppressor-height night sights, but also adaptable to future optics releases with no direct milling of the slide required.
The steel slide itself features an external extractor; a loaded chamber indicator which lets the user quickly determine whether the FN 509 Tactical firing chamber contains ammo or not; and a sight protecting slide cap. Designed for use when not shooting with an optic, this slide cap has raised sight wings that preserve the alignment of the iron sight if the pistol is dropped or jostled; it also provides a textured ramp for racking the slide against a belt loop, pants pocket or boot.
Expectedly, the tactical FN 509 slide also sports front and rear serrations which makes it easily rackable with wet, sweaty or gloved hands.
Made of polymer with replaceable steel frame/slide rails, the rugged and relatively lightweight frame features a grip texture which has been improved to enable faster follow-up shots in all conditions, and the FN 509 Tactical Black grip also comes with interchangeable backstraps which allow you to customize its size to match your hand for enhanced shooting comfort.
The frame also incorporates a MIL-STD-1913 accessory mounting rail in front of the trigger guard, and this rail provides four slots to which you can attach your choice of aftermarket accessories such as lights or lasers for better performance with the FN 509 Tactical pistol.
Made of stainless steel and cold hammer-forged, the FN-signature 4.5-inch barrel features a recessed target crown, in addition to a polished chamber and feed ramp. It also boasts 1/2″ x 28 threads which make it possible for the user to attach the bulk of 9mm suppressors available; and a thread cap with integrated O-ring completes the top end, preventing any suppressor attached to the FN Gun 9mm from loosening during use.
The striker-fired trigger offers a pull of 5.5 to 7.7 lbs., and, while it lacks a manual safety switch, the pistol is equipped with four passive safety systems: a striker block, a drop safety, a trigger disconnect and a trigger safety lever. These non-manual safeties present on the FN 509 Tactical ensure that the firearm will only go off when its trigger has been pulled.
Built with both right and left-handed users in mind, this handgun comes with ambidextrous operating controls, including the slide stop lever and magazine release. While some models ship with one 17-round and one 24-round magazines, two (2) 10-round, flush-fitting magazines ship with this particular model of the tactical FN 509.

FN 509 Tactical Additional Information
Barrel
Cold hammer-forging, the process which the FN Tactical 509 barrel was put through, is one which improves both the strength and durability of steel.
This rifling method also creates a smoother surface than others and produces a straight and uniform bore that is ideal for high-precision applications. Cold hammer-forged barrels tend to deliver more accuracy as a result.
The barrel muzzle has a target crown machined into it to protect the rifling and preserve the accuracy of the tactical FN 509, because the dynamics of the bullet as it exits the muzzle is very likely to be negatively impacted if the very edge of the bore is slightly damaged in any way.
Thanks to the polished chamber and feed ramp, the pistol is able to achieve smoother and more reliable feeding of ammunition.
Sights
The Trijicon HD™ Night Sights installed on the FN 509 Tactical were specifically created to address the needs of tactical shooters. The front sight of this three dot green tritium night sight set features a taller blade and an aiming point ringed in photoluminescent paint, while the rear sight is outlined in black and features a wider U-shaped notch:

This unique configuration of the tactical FN 509 sight set increases visibility and quickens front sight acquisition – even in transitional lighting. In addition, the front surface of the rear sight is steeply hooked to assist in emergency one-handed slide operation.
Bear in mind that green tritium lamps are warranted for 12 years from date of manufacture.
More info on this sight set is available here.
Magazine
The FN 509 Tactical mag is made of stainless steel and features a polymer base plate. It also comes with a high visibility, low-friction follower which is designed to minimize jams and misfeeds.
Box Contents
This FN 509 Tactical ships with two interchangeable backstraps; a locking device; an owner’s manual; a soft pistol case with FN logo; and of course, two 10-round magazines.
