CZ DUTY 4.0 F
Specs at a glance
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.
What is new under the slide is the serial-numbered 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 4 mm (0.16 in) 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 dot sights.
Full-size means 17+1 rounds, a grip that takes the whole hand and a frame 143 mm (5.6 in) high. With the extended floor plate the count goes to 19+1. Empty weight is 780 g (27.7 oz), which soaks up recoil without making the gun heavy on a belt.
The standard model skips the manual safety and keeps the three passive ones: firing pin block, trigger safety and drawbar safety. Same chassis, same trigger and slide as the MS; only the lever is missing.
The CZ DUTY 4.0 F 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.
- 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.
