The FN 503, inspired by FN's legendary heritage, is the company's first entry into the slim 9mm pistol market. The FN 503, roughly the size of your hand, conceals quickly and discreetly without compromising on features or performance. The excellent trigger and soft recoil of this slim 9mm pistol make the FN 503 comfortable and controllable to shoot.
