CZ DUTY 4.0 F
Specs at a glance
About this product
Builders who have finished a few Gen 3-pattern frames sometimes want one pistol in the safe that came out of a factory box with the serial already on it. CZ's new DUTY 4.0 is our pick for that slot. It is a striker-fired 9x19mm built the chassis way: the serialized part is an internal chassis, and the fiberglass-reinforced polymer grip frame around it is modular. The slide is cut for direct-mount optics, with fixed sights standard.
Capacity depends on the size you pick. The C compact loads 15+1, or 17+1 once the extended base plate goes on, and weighs 770 g at 135 mm tall. The F full-size loads 17+1, 19+1 extended, and weighs 780 g at 143 mm tall. Both carry a 4-inch barrel with no threads and use a refined SFDA trigger at about 5.6 lbs with a 4 mm reset. Order the MS variant if you want a manual thumb safety too. CZ puts MSRP at $729.
Pick the F when the gun lives on a belt or in a nightstand rather than under a T-shirt. Over the short-grip it adds two rounds (17+1 against 15+1), about 8 mm of grip and 10 g of weight, and nothing else changes.
This version has no external safety lever. It relies on three automatic safeties, firing pin block, trigger safety and trigger bar safety, and the trigger is the same as on the MS model. Shooters who prefer a lever should pick the MS.
The chassis is serial-numbered and modular, which is CZ's way of making the frame module swappable. The frame itself is fiberglass-reinforced polymer, 33 mm (1.3 in) wide, on a four-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.
Best fit: the belt, the nightstand and the range; the version to buy if you rarely need to hide the gun. Shooters coming from a CZ 75 will recognize the grip angle; buyers coming from any other striker gun will notice the trigger first.
Because this one arrives serialized, it ships to your FFL dealer instead of your house. Name the dealer at checkout. The dealer completes the paperwork and applies the rules of the state where you pick the pistol up, whatever those are; we do not add conditions of our own. Frames and parts ordered alongside it still ship to your door.
