CZ DUTY 4.0 F
Specs at a glance
About this product
Most of what we list goes inside a gun you already own. This page is different: a complete, factory-built CZ service pistol for the customer who wants a ready-to-shoot 9mm out of the box. The DUTY 4.0 is CZ's new-generation striker gun, sold as the C compact and the F full-size, each with a plain version or an MS version that adds a manual thumb safety on top of the firing pin block, trigger safety and trigger bar safety.
Trigger people will care about the trigger first. CZ lists the refined SFDA unit at 25±4 N, roughly 5.6 pounds, with 9 mm of travel and a crisp 4 mm reset, which is short for a factory striker pistol. The polymer frame is fiberglass-reinforced, the 4-inch barrel is not threaded, and the slide is cut for direct-mount optics. Serialization lives on the internal chassis, so the grip frame is modular. MSRP sits at $729.
CZ built the DUTY around a registered chassis that the polymer grip module wraps around, the same idea that lets a owner change frame size without buying a new registered gun. The trigger is a refined SFDA striker unit, 25 ± 4 N (5.6 ± 0.9 lbs) pull, 4 mm (0.16 in) reset, 9 ± 1 mm (0.4 ± 0.04 in) travel. The slide takes optics by direct mounting; CZ's product photos show Holosun, Aimpoint and Shield units in place. Sights are fixed, the 4-inch barrel is not threaded.
Capacity on the full-frame is 17+1 standard and 19+1 with the extended base plate. Height 143 mm (5.6 in), empty weight 780 g (27.7 oz). It is the duty-belt, range and home-defense version of the line, and the one most owners find easiest to shoot well.
No manual thumb safety here. The firing pin block, trigger safety and trigger bar safety handle drop safety, and the holster handles the rest. CZ sells the same gun with a thumb safety lever as the MS model.
Best fit: the belt, the home-defense 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; owners coming from any other striker gun will notice the trigger first.
Because this is a serialized firearm, it cannot ship to your door like a trigger kit. At checkout you name the FFL dealer who will receive it, and the pistol travels to that shop with tracking. The dealer completes the transfer paperwork and follows whatever your state requires at pickup, so check with them first on what to bring.

Frequently asked questions
- Can I swap the trigger in the DUTY 4.0 the way I do on an AR?
- It ships with CZ's own SFDA trigger at about 5.6 pounds, and we have not listed drop-in replacements for it yet.
- What does the MS in the model name mean?
- MS models add a manual thumb safety to the standard firing pin block, trigger safety and trigger bar safety; the non-MS models rely on those three internal safeties alone.
- How many rounds does the CZ DUTY 4.0 F hold?
- 17+1 with the standard magazine and 19+1 with the extended base plate.
- Can I put a red dot on it?
- Yes. The slide is optics-ready with direct mounting; CZ's photos show Holosun, Aimpoint and Shield dots fitted.
