The FN57 has the highest magazine capacity of all the pistols at 20+1 rounds, and the second highest bullet velocity, only behind the .44 Magnum. However, it has the lowest damage of any semi-automatic pistol, tied with the QSZ-92. Unlike the M9 and P226, its recoil mainly kicks straight up, making a Compensator largely unnecessary.
A Laser Sight is useful for improving hip-fire accuracy, while a Muzzle Brake can be good to help control vertical recoil if necessary. As with all pistols, the Ghost Ring Sight, Mini (RDS), or Delta (RDS) can be attached.
