CZ DUTY 4.0 F MS
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.
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.
Under the DUTY name sits a registered modular chassis, a 33 mm (1.3 in) wide fiberglass-reinforced polymer frame, a 4-inch barrel and a trigger CZ rates at 25 ± 4 N (5.6 ± 0.9 lbs) with a 4 mm (0.16 in) reset. The slide is optics-ready by direct mount rather than an adapter plate. Fixed sights come standard, and the barrel is not threaded.
This is the version with a manual thumb safety. The three passive safeties (firing pin block, trigger safety, trigger bar safety) are the same as on every DUTY; the lever is an extra for people who were trained on one or simply want one.
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.
- Is the CZ DUTY 4.0 F MS the same gun as the F?
- Yes, apart from the manual thumb safety. Chassis, trigger, slide and the 17+1 capacity are identical.
- Who should pick the MS version?
- Anyone trained on a manual safety or who wants a positive on/off control, including many agency buyers.
