FN America 3848950463: Chambered in the 5.7x28mm cartridge, the FN PS90 utilizes blowback operation and fires from a closed bolt for greater accuracy and reliability. The FN PS90's 16.04" cold hammer-forged Mil-spec barrel is equipped with an integrated muzzle brake to reduce recoil. Dual magazine latches, cocking handles, and an innovative synthetic thumbhole stock with a molded-in sling attachment point help make the FN PS90 fully ambidextrous. Note- This model is the Law Enforcement model, meaning it features a magazine with a 50-round capacity compared to the typical 30-round magazine.
