Last updated July 25, 2026. The FN Five-seveN is the pistol that started the 5.7x28mm craze. FN invented the cartridge, built the P90 and the Five-seveN around it, and created a handgun that holds 20+1 rounds, recoils like a .22, and shoots flat and fast. The latest MRD version adds an optics-ready slide to the formula. It is expensive to buy and feed, and its terminal performance is endlessly debated, but nothing else feels quite like it. Here’s the honest verdict.

The Original 5.7 Experience
The Five-seveN’s appeal is a combination no other pistol quite matches: 20 rounds of a high-velocity, flat-shooting cartridge with almost no recoil, in a package that weighs next to nothing. The 5.7×28 leaves the long barrel at rifle-like velocities, so the trajectory is flat and the muzzle barely rises between shots, making fast, accurate strings effortless. FN’s decades of experience with the round show in the reliability and the thoughtful ergonomics: ambidextrous controls, a comfortable (if large) grip, and on the MRD model, an optics-ready slide for a red dot. It is a genuinely unique shooting experience.
How the Five-seveN Shoots
On the range the Five-seveN is pure fun. The recoil is so mild that new shooters grin and experienced shooters shoot tiny groups, and 20+1 capacity means long strings between reloads. It is accurate, reliable, and easy to run fast. The honest caveats are cost and terminal debate: the gun is expensive, 5.7×28 ammo costs far more than 9mm, and experts argue endlessly about its stopping power relative to a good hollow point. The grip is also large for smaller hands. As a range gun, a flat-shooting plinker, or a niche defensive option, though, it delivers something no 9mm can.
FN Five-seveN Variants
The current line centers on the optics-ready MRD, with the classic model still around on the used market.

FN 5.7 Ammo Note Varies
Budget for the ammo: 5.7×28 costs well above 9mm, a real ongoing cost of ownership.
Where to Buy the FN Five-seveN
The Five-seveN now has real competition in its own caliber: the Ruger 57 undercuts it dramatically on price, and the Smith & Wesson M&P 5.7 adds an optic-ready slide and a clever gas-operated action for less money too. The FN is the original and arguably the most refined, but you pay for it. Compare live prices below, and see the whole class in our best 5.7 pistols guide.
Who Should NOT Buy the FN Five-seveN
- Value buyers: the Ruger 57 delivers the same caliber and capacity for hundreds less. If you want the 5.7 experience on a budget, start there.
- Cheap-plinking shooters: 5.7×28 ammo costs far more than 9mm. High-volume range days get expensive fast.
- Primary self-defense buyers on a budget: the terminal-performance debate and cost make a proven 9mm a more economical defensive choice for many.
- Small-handed shooters: the grip is large. If it doesn’t fit your hand, a smaller-framed pistol will serve you better.
The Verdict
The FN Five-seveN is the original and still one of the best 5.7×28 pistols: flat-shooting, ultra-low-recoil, high-capacity, and refined by decades of FN experience. It is expensive to buy and feed, and rivals like the Ruger 57 now deliver the experience for far less, but for the definitive 5.7 handgun, the FN is it.

Our Rating: 8.5 / 10 — the definitive 5.7 pistol, if you can stomach the gun and ammo cost.
