One catalog, fifty states, and now one more CZ striker gun in it. The DUTY 4.0 is the new-generation 9x19mm from CZ, sold as the C compact and the F full-size, each available plain or as an MS model with a manual thumb safety. Under the fiberglass-reinforced polymer grip frame is a serialized modular chassis, so the frame itself is a separate module.

Buyers come to us for a first gun bought online, and this one suits that job: fixed sights so there is nothing to zero, a direct-mount optics cut if you want a dot later, a 4-inch unthreaded barrel and a 1.3-inch width. The C holds 15+1, the F 17+1, and each gains two rounds with the extended base plate. The SFDA trigger breaks at about 5.6 pounds and resets in 4 mm. MSRP is $729 across all four.

The C is the compact frame. It stands 135 mm (5.3 in) tall, weighs 770 g (27.2 oz) unloaded and carries 15+1 rounds of 9mm, or 17+1 once the extended base plate is fitted. Short enough to hide under a shirt, long enough to get every finger on the grip.

MS stands for external safety. This model adds a thumb lever to the internal safeties every DUTY has: the firing pin block, the trigger safety and the drawbar safety. Agencies and buyers who want a positive on/off control choose this version; the trigger itself is unchanged.

The chassis is registered and modular, which is CZ's way of making the grip module swappable. The frame itself is fiberglass-reinforced polymer, 33 mm (1.3 in) wide, on a 4-inch barrel and a 188 mm (7.4 in) overall length. The SFDA trigger breaks at 25 ± 4 N (5.6 ± 0.9 lbs) and resets in 4 mm (0.16 in). Optics mount directly to the slide; the photos from CZ show Holosun, Aimpoint and Shield footprints.

Who is it for: daily carry, a bedside gun that also rides along, and new buyers who want one pistol for everything. If you already shoot a P-10, the DUTY is the next step in the same family, with a new chassis and the optics done right.

We ship to FFL dealers in every state that allows the item. Name your licensed dealer at checkout and the pistol goes to them; your dealer applies your state's permit, waiting-period and magazine rules at pickup, and supplies compliant magazines where your state requires them. Ammunition, optics and parts ship to your door where your state allows it. Price and availability are confirmed when you order, before you pay.

Questions buyers ask: What if my state has magazine rules? Your dealer applies your state's magazine rules at pickup and supplies compliant magazines where required; checkout and your dealer sort it out, not you. Is the grip frame the serialized part? No. On the DUTY 4.0 the serial number is on the internal chassis, and the polymer grip frame is a module around it. What does MS mean on the CZ DUTY 4.0 C MS? Manual safety. It adds a thumb lever to the firing pin block, trigger safety and drawbar safety that every DUTY has.
