help FN Five-seveN FAQ
Why does the FN Five-seveN use the 5.7x28mm cartridge?
FN developed the cartridge for its P90 personal-defense weapon and then chambered the Five-seveN pistol for the same ammunition family. The small, bottlenecked cartridge permits a high-capacity magazine and relatively light recoil.
Does the FN Five-seveN use the same ammunition as the FN P90 and PS90?
Yes, all three are chambered in 5.7x28mm. Specific projectile types and legally available loads vary between military, law-enforcement, and civilian markets.
How many rounds fit in a standard Five-seveN magazine?
The commonly supplied full-capacity magazine holds 20 rounds. Lower-capacity magazines are offered where required by law, and extended products also exist in some markets.
How does the FN Five-seveN differ from the Ruger-5.7?
Both are full-size, polymer-framed pistols chambered in 5.7x28mm, but they use different magazines, controls, and internal designs. The FN model was created as a companion to the P90, while Ruger entered the commercial 5.7mm pistol market much later.
