The FN Five-SeveN is a semi-automatic pistol designed and manufactured by FN Herstal in Belgium. The pistol is named for its armor piercing 5.7x28mm cartridge, the same round used in the FN P90. The Five-SeveN can accept 20 and 30-round magazines. Its externals are made largely of polymer, thus reducing the weight drastically.
The Five-SeveN appears in two games in the Battlefield series, named the FN57.
