CZ DUTY 4.0 F MS
About this product
Someone who has finished a frame on a jig knows exactly what a serialized chassis means, and that is where CZ's new pistol gets interesting. On the DUTY 4.0 the number lives on the internal chassis, while the fiberglass-reinforced polymer grip frame is a modular shell around it. It is sold as the C compact, the F full-size, and MS versions of both that add a manual thumb safety to the firing pin block, trigger safety and trigger bar safety.
We list it for the customer who wants one ready-made 9mm beside the project gun. Both sizes carry a 4-inch barrel with no threads, fixed sights, and a slide cut for a red dot straight on the metal. Length is 188 mm and width 33 mm. The refined SFDA trigger pulls 25±4 N, travels 9±1 mm and resets in 4 mm. The compact holds 15+1 and the full-size 17+1, each gaining two rounds with the extended base plate, and CZ puts the MSRP at $729.
CZ built the DUTY around a serial-numbered chassis that the polymer polymer grip wraps around, the same idea that lets a owner change frame size without buying a new serial-numbered 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 102 mm barrel is not threaded.
Capacity on the full-frame is 17+1 standard and 19+1 with the extended floor 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.
A manual 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 drawbar safety, and does not change the trigger pull.
The CZ DUTY 4.0 F MS suits anyone who wants a modern optics-ready 9mm with CZ's grip and a trigger that is better than the class average: the belt, the home-defense and the range; the version to buy if you rarely need to hide the gun.
A complete pistol follows a different path than a frame kit. Instead of coming to your door, it ships tracked to the FFL dealer you name at checkout, and that dealer completes the transfer and applies the rules of your state when you pick it up. Check that your chosen dealer accepts inbound transfers before you order, and enter their details with the pistol.

Frequently asked questions
- Can I swap the grip frame on the DUTY 4.0 like I swap a P80 frame?
- The serialized part is the internal chassis, so by design the grip frame around it is modular; we do not list spare grip frames for it at this time.
- Does it come with a jig or tools?
- No. It is a finished factory pistol, so there is nothing to mill or drill; it arrives ready to shoot after the transfer.
- 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.
