The original 5.7 FN, often imitated but hardly duplicated, has two decades of trusted service with allied armies, global law enforcement, and civilians. Extending its groundbreaking design is a new, all-flat dark earth frame and slide. With improved range and accuracy over common pistol cartridges, the NATO standardized 5.7x28mm developed by FN Herstal is fired from the chrome-lined cold hammer-forged barrel. Pinpoint accuracy and minimal felt recoil is standard issues. Equipped with an internal hammer, the smooth trigger with a predictable break further enhances accuracy. Four new models include all black, and all FDE, with 10-rd or 20-rd magazines, included. Two existing California-compliant Five-seveN models with 10-rd magazines remain unchanged.
