Best FN Pistols (2026): 509, Reflex, Five-seveN & More

The best FN pistols come from a company that has armed militaries for more than a century, and it shows in how hard these guns run. FN America builds the 509 striker-fired family, the hammer-fired Reflex micro-compact, the Five-seveN, and big .45s like the 545 and FNX-45 Tactical.

Our writers have put a lot of rounds through them. A Reflex printed a 0.85 inch best group and ran hundreds of rounds dirty without a problem, a 509 LS Edge went 600 rounds over two days without an issue, a 509 Midsize MRD ran 300 rounds without cleaning, and a Five-seveN rang an 18 inch steel plate at 300 yards.

This guide picks the best FN pistol for each job, from pocket carry to duty and competition. If you are cross-shopping other brands, see our best Glock alternatives guide. Every price is labeled with when we saw it.

Buyer’s Guide: How To Choose The Best FN Pistols In 2026

FN pistols fall into a few families. Start with size and caliber.

The 509 Family

The 509 is FN’s striker-fired 9mm, built from work on a U.S. Army pistol trial. It comes in full size, Midsize, Compact, and Edge versions, and most current models are optics ready with FN’s MRD system. The 509 CC Edge adds a compensator, and the 509 LS Edge adds a 5 inch barrel for duty and competition.

Reflex And 503 For Deep Carry

The Reflex is a hammer-fired micro-compact with 11 and 15 round magazines. The 503 is a slim single-stack 9mm at 1.1 inches wide. Our Reflex reviewer found it fully reliable, and the 503 had a few early issues that settled down after break-in. We also filmed a Reflex unboxing and first 100 rounds.

The Five-seveN

The Five-seveN fires 5.7×28 from 10 or 20 round magazines and weighs about 21 ounces without a magazine. It is light, flat shooting, and pricey. See our best 5.7×28 pistols guide to compare it with newer rivals.

.45 ACP Options

FN builds two high-capacity .45s. The 545 Tactical holds 18+1, and the hammer-fired FNX-45 Tactical holds 15 and is built to run a suppressor. Both are big pistols.

Triggers

Most FN triggers we measured landed near 5 pounds. The Reflex averaged right at 5 pounds, the 509 CC Edge and 509 LS Edge broke at 5 pounds, and the 509 Compact MRD at 5.5 pounds. The Five-seveN was the outlier at 6 pounds.

Price

In our reviews, prices ran from $549 for the 503 in 2022 to $1,569 for the 509 CC Edge in 2023. The Reflex listed at $599, or $659 with the MRD, as of our 2026 review. Several reviews are older, so check current listings.

Our reviewer measured a consistent 5 pound break with about 0.10 inch of creep and shot close to 1 inch groups at 10 yards with Norma ammo. The iron sights sit low enough to co-witness with an optic. He warned that a heavy optic plus the compensator can cause problems with light ball ammo.

• Capacity: 12 or 15 rounds

FN 509 LS Edge: Best FN For Duty And Competition (2026)

The FN 509 LS Edge is the best FN for duty and competition because its 5 inch barrel and long slide make it easy to shoot well at distance. It is 8.2 inches long, came with three 17-round magazines, and also takes FN’s 24-round magazines. The optic plate doubles as wings to protect the rear sight.

Read our full FN 509 LS Edge review here.

Our reviewer measured the trigger at 5 pounds and called it very nice. He ran 600 rounds over two days without an issue, cleaned failure-to-stop and box drills with A-zone hits, and hit an IPSC target at 50 yards with iron sights. It is a big gun that is tough to carry concealed.

It proved completely reliable with multiple loads. At 15 yards, Speer 230 grain Gold Dot grouped 1.5 inches and Federal 230 grain HST 1.75 inches. Our reviewer also shot it suppressed with an Osprey can and said the weight soaked up a lot of recoil.

It ships with three high-capacity magazines in a hard case. Our reviewer praised the interchangeable backstraps as the best system in the industry.

Read our full FN 503 review here.

Our reviewer’s wife could not rack the slide with a full 8-round magazine at first, but that eased after about 150 rounds. He had one failure to fire with Magtech, which he blamed on a hard primer, and one stovepipe with steel-cased ammo. After break-in it kept running.

Key Specs

• Caliber: 9mm
• Capacity: 6 and 8 rounds
• Width: 1.1 in
• Weight: 21 oz
• MSRP: $549 at the time of review (2022)

FN FNS-9 Longslide: Best Value Used FN (2026)

The FN FNS-9 Longslide is the best value used FN because it delivers competition-gun performance from a plain 5 inch striker-fired pistol. It has a cold hammer-forged stainless barrel, a captured flat wire recoil spring with a weighted extension for softer recoil, and our sample came with three 17-round magazines.

Read our full FN FNS-9 Longslide review here.

The trigger broke cleanly at just under 5 pounds, and our reviewer said reliability was what you would expect from FN. This 2017 review predates the 509, which has since taken over as FN’s main striker-fired line, so look for an FNS on the used market.

Key Specs

• Caliber: 9mm
• Barrel: 5 in stainless
• Magazines: three 17-round
• Trigger: just under 5 lb
• Price: check used listings

Pros
