CZ DUTY 4.0F MS 9mm 4" 10rd Manual Safety Pistol

The CZ DUTY 4.0F MS is the full size, 4" barrel CZ DUTY with one addition: an ambidextrous manual thumb safety. It sits on top of the pistol's three stage drop safety system (drop safety, trigger safety and out of battery safety), so shooters who train with a thumb safety can keep doing so on a modern striker gun. Like every DUTY, the pistol is built on a serialized chassis that holds the working parts, and the grip module around it can be swapped. A medium black module is installed, with small and large sizes available for different hands. Two 10 round magazines are included.

CZ gave the DUTY a patented striker trigger with smooth travel, a crisp break and a short reset. The barrel is cold hammer forged, and the slide wears CZ's nitride finish, which resists corrosion. For optics, the slide takes RMR, RMSc, Holosun K and DeltaPoint Pro pattern red dots directly with the included pin set, and the H3 tritium three dot night sights sit low enough to co-witness. The polymer frame has a Picatinny rail, the slide release and magazine release work from either side, and the grip cutout plus a serrated base plate help on reloads. Disassembly does not require a trigger pull, and CZ proofed the design with 25,000 overpressure rounds.
