The P320-M17 MS combines a full-size 4.7-inch barrel with a 6.49-inch sight radius for stable aiming and controlled recoil. Its coyote-finished, stainless-steel slide provides corrosion resistance, and the front and rear cocking serrations offer positive manipulation.
The modular, serialized Fire Control Unit enables reconfiguration within the P320 family, allowing changes to grip modules and other compatible components. The full-size coyote grip module features molded texturing for a secure hold.
Controls are duty-focused with ambidextrous manual thumb safeties and ambidextrous slide catch/release levers. The rear sight is mounted on a removable, screw-retained plate, supporting an optic-ready configuration, while the front sight is dovetailed with a dot for quick reference.
The dust cover carries an M1913 accessory rail for mounting compatible lights or accessories. The pistol is paired with two 21-round extended magazines and one 17-round flush-fit magazine for a 21+1 capacity when using the extended mags.
