FN 509 LS Edge Tactical Hits $699: 55% Off at PSA

Last updated May 2026 · By Nick Hall, tracks live retailer pricing across the FN 509 family for USA Gun Shop’s deals database

Quick take: Palmetto State Armory just dropped the FN 509 LS Edge Tactical to $699.99, down from $1,553.99 MSRP. That is a 55% discount, $854 off on FN’s long-slide optics-ready 9mm. PSA is listing the gun in black and gray with three 17-round magazines included. Buy it here now.

What it is: FN 509 LS Edge Tactical 9mm. 5-inch threaded PVD barrel, optics-ready slide cut for FN’s Low-Profile Optic Mounting System, lightening-cut slide, flared aluminum magwell, flat-faced trigger, and fiber-optic sights. SKU 66-100843, black-and-gray finish.
Deal price: $699.99 at Palmetto State Armory.
MSRP: $1,553.99.
Why it matters: Deepest discount we have tracked on the LS Edge Tactical SKU this year. Three 17-round magazines in the box bring per-mag value down meaningfully. Optics-ready out of the box, no slide-cut machining required.

Most “55% off MSRP” claims are inflated against an MSRP nobody actually pays. The FN 509 LS Edge Tactical at $1,553.99 MSRP runs $1,200 to $1,350 at street pricing across most distributors, so the real-world discount against street is more like 45% than 55%. That still makes today’s PSA listing the lowest price on the LS Edge Tactical anywhere right now and the deepest cut we have tracked on this SKU in the past twelve months.

How we tested: Every pick here was run through our testing methodology. Minimum round counts, accuracy and reliability protocols, the failures that disqualify a gun. If we haven't shot it, we don't recommend it.

What’s In the LS Edge Tactical Box at $699

The 509 LS Edge Tactical is the long-slide tactical configuration of the FN 509 platform. Barrel is 5 inches, stainless steel with a PVD coating, threaded 1/2×28 at the muzzle for suppressor or muzzle-brake use. Overall length is 8.4 inches. Empty weight is 28.6 ounces.

The slide is the LS Edge competition slide with lightening cuts on the top and sides, factory-cut for the FN Low-Profile Optic Mounting System. That is FN’s proprietary optic-mounting cut that uses pin-and-slot indexing rather than a plate system. The cut covers Trijicon RMR, RMRcc, Holosun 507C, Aimpoint ACRO, and SIG Romeo footprints with the appropriate FN plate.

The trigger is the LS Edge flat-faced trigger with a published pull weight of roughly 5 pounds and a clean, audible reset. The magwell is flared aluminum, color-matched to the slide. Sights are fiber-optic suppressor-height for tactical use with optics. Three 17-round magazines ship in the box.

For the broader FN 509 lineup context, our roundup of the best optics-ready pistols ranks the LS Edge against the Glock 17 MOS, the Sig P320 X-Five Legion, and the S&W M&P 2.0 Performance Center. The LS Edge sits in the top tier on accuracy and trigger feel; the price has been the barrier.

How $699 Compares to the Real Market

FN street pricing on the LS Edge Tactical has run $1,200 to $1,350 at most major distributors over the past eighteen months. Brownells has listed it around $1,279. Sportsman’s Warehouse around $1,299. Cabela’s around $1,349. The PSA $699.99 is roughly $500 below the next-lowest live listing we tracked this morning.

For the optics-ready pistol segment at this build tier, $699 buys you a Sig P320 X-Compact or a Glock 19 MOS with no spare magazines. Both are good guns. Neither has a 5-inch slide, factory-flared magwell, or three magazines in the box. The LS Edge Tactical at $699 is competing structurally with $1,200 guns, not $700 ones.

For competition or duty buyers who have been waiting for an optics-ready long-slide at sub-$1,000, this is the cleanest entry into the LS Edge family in twelve months. Our deals tracker logs the live retailer price every four hours and the next-lowest live FN 509 LS Edge price was $1,229 as of this morning.

Stock and Timing

PSA showed this deal live as of May 13, 2026 in the standard FN 509 LS Edge Tactical configuration (black-and-gray, SKU 66-100843). PSA daily-deal pricing rotates frequently and a 55% discount on a flagship FN tier is the kind of price point that does not sit live for weeks. If the LS Edge Tactical has been on your shortlist, treating this as a 7-to-10-day window is the right call rather than waiting for a deeper cut.

PSA also runs flat-rate shipping that lands around $20 to $25 for a handgun shipment to an FFL. The optics plate for the FN Low-Profile Optic Mounting System is sold separately and ships with whichever footprint your optic uses. Total all-in for the gun, the FFL transfer, and the optic plate is roughly $740 at the worst case.

The Bottom Line

$699.99 on a $1,200-street optics-ready long-slide FN is the deal of the week in the handgun segment. The three magazines in the box take the per-magazine math from $40 each (FN factory mags retail around that) down to $0. The threaded muzzle takes a $50-to-$80 thread-pitch-adapter step out of the suppressor-pairing math. Track the live handgun deals page if the LS Edge sells out before you commit.

Frequently Asked Questions

What is the FN 509 LS Edge Tactical?

The FN 509 LS Edge Tactical is the long-slide tactical variant of the FN 509 platform. It carries a 5-inch threaded PVD barrel, a competition lightening-cut slide, the FN Low-Profile Optic Mounting System for direct red-dot mounting, a flared aluminum magwell, and a flat-faced LS Edge trigger. SKU is 66-100843 in the black-and-gray finish. MSRP is $1,553.99.

How much does the FN 509 LS Edge Tactical normally cost?

MSRP is $1,553.99. Street pricing across major distributors typically runs $1,200 to $1,350 over the past eighteen months. The PSA $699.99 deal represents roughly 45% off the real street price and 55% off the published MSRP.

Is the FN 509 LS Edge Tactical optics-ready?

Yes. The slide ships factory-cut for FN's Low-Profile Optic Mounting System (LPOMS), which uses pin-and-slot indexing rather than the more common plate system. LPOMS plates are sold separately and cover Trijicon RMR/RMRcc, Holosun 507C, Aimpoint ACRO, and SIG ROMEO footprints depending on which plate you buy.

How many magazines come with the FN 509 LS Edge Tactical at $699?

Three 17-round magazines ship in the box. FN factory 17-round 9mm magazines retail at $35 to $45 each, so the three-magazine inclusion adds roughly $100 to $130 of value at the per-mag street price.

Is the FN 509 LS Edge Tactical suppressor-ready?

Yes. The 5-inch barrel is threaded 1/2x28 TPI at the muzzle, which is the standard thread pitch for 9mm pistol suppressors. The fiber-optic sights ship at suppressor-height, so a typical 9mm suppressor co-witnesses cleanly without sight upgrades.

How long does the $699 PSA deal last?

Palmetto State Armory daily-deal pricing rotates frequently and PSA has not published an end date on the LS Edge Tactical promotion. As of May 13, 2026 the listing is live. Treat this as a 7-to-10-day window rather than expecting weeks of availability. The live pricing card above tracks PSA and competing retailers every four hours.

Is the FN 509 LS Edge Tactical good for competition?

Yes. The LS Edge family was built around USPSA and IDPA competition use. The flat-faced trigger, aluminum magwell, lightening-cut slide, and 5-inch sight radius are all competition-optimized features. The Tactical variant adds suppressor-height sights and the threaded barrel, which pivot the platform slightly toward tactical and duty use, but the core competition pedigree carries through.

Where does the LS Edge fit in the FN 509 lineup?

The FN 509 platform runs from the Compact (3.7-inch barrel) up through the standard Service (4-inch), the Tactical (4.5-inch threaded), the LS (5-inch competition), and the LS Edge / LS Edge Tactical (5-inch competition with LPOMS optic cut and the lightening-cut slide). The LS Edge Tactical is the top of the lineup for the duty and competition crossover use case.
