57x28mm Handguns

The FN Five-seveN is a semi‑automatic pistol designed around the proprietary 5.7×28mm cartridge, emphasizing low recoil, high capacity and the ability to defeat soft body armor. Conceived as a compact, lightweight sidearm for military and law‑enforcement operators, it combines a polymer frame with a steel slide and a short‑stroke gas‑delayed blowback system that allows reliable cycling of the high‑velocity bottleneck round. Its 20‑round double‑stack magazine, ergonomic grip angle and interchangeable backstraps provide a customizable fit, while the low bore axis and linear recoil impulse give rapid follow‑up shots. The pistol’s reputation rests on its unique ballistic performance—high muzzle velocity (≈ 715 m/s) and flat trajectory—making it effective at extended pistol ranges and capable of penetrating many NATO‑standard soft armors. The Five‑seveN’s distinctive features include a polygonal rifled barrel, ambidextrous controls, and optional suppressor‑ready threaded barrel, setting it apart from conventional 9 mm pistols.

The Ruger 57 is a semi-automatic pistol chambered in 5.7x28mm, Ruger's entry into the high-velocity PDW caliber market. It features a polymer frame with an aluminum alloy slide and a cold hammer-forged barrel. The pistol has a 20-round magazine capacity, giving it exceptional firepower for its size. Its ergonomic design includes a thin grip profile, ambidextrous safety, and cocking serrations on both front and rear of the slide. The Ruger 57 delivers the flat trajectory and low recoil characteristic of the 5.7x28mm cartridge.
