FN Introduces Trimmed Down 509 Midsize Model


Right-sized for concealed carry, the 509 Midsize is trimmed down, yet still optimized for superior performance.

How the 509 Midsize is optimized for carry:

  • Grip reduced in size.
  • Barrel length maintained at 4 inches.
  • 10- and 15-round magazines standard.
  • Compatible with standard 17- and 24-round 509 magazines.

Born from the Army’s Modular Handgun System competition, the FN 509 has made quite a splash in the civilian market. And the Belgian-based gunmaker has expanded the offerings of the polymer-framed, striker-fired pistol by two for the new year.

The weightier release, the FN 509 Midsize is a trimmed down iteration of the original 9mm, aimed at making the pistol more wieldy for carry. Wisely, FN kept the barrel length the same (4-inches) and focused on shortening the grip. Overall, this should make it more concealable, yet maintain a longer sight radius. Though, the 509 Midsize may not appeal to some, given its terse grip affects one of the appealing features of the original — capacity. The Midsize version comes with 10- and 15-round magazines, a significant reduction from the 17- and 24-round mags of the earlier iteration. But if you need that sort of firepower, never fear, the Midsize 509 is compatible with the standard magazines.

Alongside the FN 509 Midsize release, the company has introduced a matte black finished model of its optics-ready 509 Tactical. Originally, the polymer-framed pistol came in Flat Dark Earth. Outside of a color upgrade, the 509 Tactical comes with everything on the original, including optics-ready mounting system with co-witnessing suppressor-height night sights, 4.5-inch threaded barrel and 24-round magazine.

From FN:

(McLean, VA – January 7, 2019) FN America, LLC is pleased to announce the release of the FN 509 Midsize, a new carry option in the FN 509 series of striker-fired pistols. Additionally, the FN 509 Tactical is now available in a matte black finish. These line extensions further FN’s commitment to offer a full line of options in the FN 509 series that meets all customer expectations.

“What truly sets FN products apart is the quality. When customers pick up the FN 509 in comparison to other striker-fired 9mm’s, they instantly notice the ergonomics, premium finishes and price point that is competitive,” noted Chris Cole, Vice President of Sales and Marketing for FN America, LLC. “With the FN 509 Midsize and FN 509 Tactical in black, customers will now have four additional FN options in the 9mm striker-fired category to choose from. We believe that options are always a good thing and we’re proud to provide them to our loyal customer base.”

The new FN 509 Midsize pistol is chambered in 9mm and features a four-inch slide and barrel, frame with shortened grip and 15- or 10-round magazine capacity, backward compatibility to higher capacity FN 509 magazines with use of a grip sleeve and fixed three-dot luminescent sights. From individuals seeking a do-it-all range, home defense and carry pistol to law enforcement use as a back-up duty pistol or carry model for plain clothes officers, the FN 509 Midsize is the ideal solution.

The pistol also features various upgrades including new sculpting around the magazine release for easier activation, a flatter-faced trigger for a more controlled trigger press and improved slide stop lever and texturing. FN 509 Midsize MSRP $649.

The FN 509 Tactical, the industry’s leading optics-ready 9mm striker-fired pistol, is now available in a matte black finish. The pistol features the company’s patent-pending 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, ½” x 28 threads that accept the bulk of 9mm suppressors available and thread cap with integrated O-ring to prevent loosening during use.

Lastly, the 24-round magazines, nearly identical in length to the pistol’s slide, maximize ammunition capacity without impacting carry convenience. FN 509 Tactical Black MSRP $1,049.
