The FN Five-seveN is a semi-auto handgun named for the caliber in which it is chambered - 5.7x28mm. Suitable for concealed carry and home defense, the delayed blowback action aids in reduced recoil. It offers predominantly polymer construction, as well as a concealed hammer and special safety to prevent firing without a magazine. An integral rail makes for easy mounting of accessories. This FN Five-seveN MRD features an ambidextrous thumb safety and a magazine disconnect. Purchase includes a soft case, the owner's manual, and two 10-round magazines.
