Wanted something in FDE to match SCAR. Also wanted an M17. Originally was looking at M17, but Sig P320 had recent safety concerns. I also wanted a suppressor-ready platform.

FN ran a special version and bundle of the 509 Tactical starting early 2023 (ending late 2024?). It upgrades the trigger to "FN's custom flat-faced precision trigger" and includes 3 additional mags. 66-101651/845737016814 is for the bundle while 66-100373 is the typical model.

MRSP reflects MSRP of base gun + MSRP of 3x 24 mags.

Overview from fnamerica.com 2025

The FN 509® Tactical, an extension of the FN 509 family, is based on FN's submission pistol that the U.S. Army tested for its Modular Handgun Trials, but includes the significant improvements to the design that were implemented in the FN 509. The pistol features the company's U.S Patent No. 10/352,654 Low-Profile Optics Mounting System™ that enables the platform to accept more than ten commercially-available miniature red dot (MRD) optics that co-witness with the suppressor-height night sights and remain adaptable to future optics releases with no requirement of direct milling of the slide. The slide cap, for use when not shooting with an optic, has raised sight wings that protect iron sight alignment if the pistol is dropped or jostled, and provides a textured ramp for racking the slide against a belt loop, pant pocket or boot. An FN-signature 4.5-inch, cold hammer-forged, stainless-steel barrel with target crown, 1/2" x 28 threads that accept the bulk of 9mm suppressors available and thread cap with integrated O-ring to prevent loosening during use complete the top end. Lastly, the 24-round magazines, nearly identical in length to the pistol's slide, maximize ammunition capacity without impacting carry convenience.

The FN 509® Tactical is the duty-proven pistol with upgrades tailored for the high round count shooter. This exclusive, optics-ready package includes three 24-rd magazines and two 17-rd magazines, with a flat-faced precision trigger.

With a factory-milled slide, it's ready to mount most micro red dots. FN's Low-Profile Optics-Mounting System™ is the industry's most adaptable optics mounting platform, allowing co-witness with tall tritium night sighs on the slide. A smooth, drop-safe trigger has a positive wall before a clean break. With the target-crowned, hammer forged barrel, a lifetime of tight groups is in reach.
