CZ DUTY 4.0 C MS
About this product
Slides and barrels fill most of our catalog, which makes a pistol that arrives with both already fitted an easy thing to explain. CZ's DUTY 4.0 is a new-generation striker-fired 9mm with a serialized internal chassis, a modular fiberglass-reinforced polymer grip frame, a 4-inch barrel without threads and fixed sights. The slide is cut for a direct-mount red dot, and CZ's own photos show Holosun, Aimpoint and Shield optics on it.
Pick the C compact for 15+1 and a 135 mm height, or the F full-size for 17+1 and 143 mm; either gains two rounds with the extended base plate. Add MS to the model and you get a manual thumb safety on top of the firing pin block, trigger safety and trigger bar safety. The refined SFDA trigger is rated at 25±4 N with a 4 mm reset and 9±1 mm of travel. Overall length is 188 mm, width 33 mm, and CZ's suggested price is $729.
Pick the C when the gun has to disappear under a cover garment. It gives up two rounds to the full-size model (15+1 against 17+1) and about 8 mm of grip height, and in return it is 5.3 in (135 mm) tall and 27.2 oz (770 g) light.
What is new under the slide is the serialized modular chassis. The serial number lives on the internal chassis, not on the polymer grip, so the polymer grip is a part you can change while the gun stays the same gun. Around it CZ put a reworked SFDA striker trigger, rated at 25 ± 4 N (5.6 ± 0.9 lbs) with a 0.16 in (4 mm) reset and 9 ± 1 mm (0.4 ± 0.04 in) of travel, and a slide cut for direct-mount optics. CZ's own photos show it wearing Holosun, Aimpoint and Shield red dots.
The MS model carries a frame-mounted manual thumb safety on top of the firing pin block, trigger safety and trigger-bar safety. Everything else, chassis, trigger, slide and optics cut, is the same as the version without the lever.
Best fit: concealed carry where your state allows it, home defense, and range time that does not need a full-size grip. Shooters coming from a CZ 75 will recognize the grip angle; owners coming from any other striker gun will notice the trigger first.
Parts ship to your door; a complete pistol does not. When you order the DUTY 4.0, choose the FFL dealer who will receive it, and we send it there with tracking. The dealer completes the transfer paperwork and applies the rules of your state at pickup. Pick a dealer who takes transfers and have their details ready before you check out.

- Is the barrel threaded?
- No, the 4-inch barrel on every current model is unthreaded.
- 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 trigger bar safety that every DUTY has.
- Does the manual safety change the trigger?
- No. CZ rates the trigger the same on both versions: 5.6 pounds with a 4 mm reset.
