About this product
The FN Five-seveN MK2 is the updated generation of FN Herstal's distinctive 5.7x28mm pistol, a caliber originally developed by FN for a low-recoil, high-capacity NATO sidearm and PDW system, now offered to civilian shooters in a refined, ergonomically improved package.
What is 5.7x28mm, and why is it different?
FN developed the 5.7x28mm cartridge alongside the P90 personal defense weapon as a small-caliber, high-velocity round designed to penetrate soft body armor while producing significantly less recoil than traditional pistol calibers like 9mm or .45 ACP. In the Five-seveN, that translates to a pistol that is genuinely easy to shoot quickly and accurately, even for recoil-sensitive shooters, while still delivering meaningful terminal performance from a lightweight platform. Ammunition is less universally available than 9mm, so buyers should factor that into their ongoing cost and sourcing plans.
What did FN improve with the MK2 generation?
The MK2 update refined the grip texture and ergonomics, improved the trigger over earlier Five-seveN generations, and retained the delayed-blowback operating system that makes the pistol both soft-shooting and mechanically distinct from a typical locked-breech 9mm. This configuration ships with a 4.8-inch barrel, a manual safety, and two magazines included, giving buyers a spare on day one rather than needing to source an extra magazine separately.
At just under 1.5 pounds empty, the Five-seveN MK2 is notably light for a full-size handgun, a byproduct of both the polymer frame construction and the smaller-diameter cartridge it is built around.
Who is the Five-seveN MK2 built for?
Shooters who want a genuinely low-recoil, high-capacity pistol platform, or who already own a 5.7x28mm rifle or PDW-style firearm and want a matching-caliber handgun, are the natural audience for this pistol. It stands apart from the mainstream 9mm/.40/.45 pistol market both mechanically and ballistically, which appeals to buyers looking for something distinct from a standard duty-caliber handgun. New shooters and those with hand or wrist sensitivity to recoil often find the Five-seveN notably more comfortable to shoot for extended range sessions than comparable 9mm pistols.
Because the platform and cartridge are less common than mainstream service pistols, holster and magazine pouch options are more limited than for a Glock or Sig P-series pistol, though dedicated Five-seveN accessory makers do exist. Buyers planning to shoot the pistol regularly should factor in 5.7x28mm ammunition cost and local availability, since it is typically found at specialty retailers or online rather than every general sporting goods counter.
The manual safety on this configuration gives an extra layer of mechanical security for owners who prefer that over a safety-only-via-trigger design, and the delayed-blowback action keeps the pistol mechanically simpler to maintain than a locked-breech design despite its unusual cartridge.
White dot sights come standard for a fast, high-visibility sight picture, and the polymer frame construction keeps long-term corrosion concerns to a minimum compared to an all-steel pistol, provided the barrel and other steel components receive normal cleaning and lubrication after range sessions.
As a firearm, this pistol ships to a licensed FFL dealer for the required transfer and background check, not to your home address.
