CZ DUTY 4.0 F 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.
This is the longer grip of the two DUTY frames. It holds 17+1 rounds, 19+1 with the extended plate, stands 5.6 in (143 mm) and weighs 27.7 oz (780 g) unloaded. Same slide, same 4-inch barrel as the short-grip, so the sight radius is identical; you buy the F for the grip and the extra rounds.
A manual thumb safety is the one thing that separates this model from its sibling. It sits beside the three internal safeties, firing pin block, trigger safety and trigger-bar safety, and does not change the trigger pull.
CZ built the DUTY around a serialized chassis that the polymer polymer grip wraps around, the same idea that lets a owner change frame size without buying a new serialized gun. The trigger is a refined SFDA striker unit, 25 ± 4 N (5.6 ± 0.9 lbs) pull, 0.16 in (4 mm) 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.
Who is it for: the belt, the home-defense and the range; the version to buy if you rarely need to hide the gun. 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.
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.

- No. Our slide listings name the Polymer80 frames and Gen 3 patterns they fit; the DUTY 4.0 comes with its own CZ slide and barrel installed.
- Is the barrel threaded?
- No, the 4-inch barrel on every current model is unthreaded.
- 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.
