CZ DUTY 4.0 F
Specs at a glance
About this product
Not every customer who shops frame parts wants to finish a frame. For the buyer who would rather pick up a serialized, factory-built service pistol and go shoot, we added CZ's new DUTY 4.0 in all four versions: C compact, F full-size, and the MS variants of each with a manual thumb safety. It is a striker-fired 9x19mm with a fiberglass-reinforced polymer frame, a 4-inch barrel and fixed sights.
The design will look familiar to anyone who studies how pistols are put together. CZ serialized the internal chassis rather than the grip, so the frame around it is a modular component. The slide is machined for direct-mount red dots, and CZ photographs it wearing Holosun, Aimpoint and Shield units. Trigger pull is 25±4 N, and the 4 mm reset is the number that will stand out to anyone who tunes triggers. The C carries 15+1 and the F 17+1, both gaining two rounds with the extended base plate. CZ's MSRP is $729.
Full-size means 17+1 rounds, a grip that takes the whole hand and a frame 5.6 in (143 mm) high. With the extended base plate the count goes to 19+1. Empty weight is 27.7 oz (780 g), which soaks up recoil without making the gun heavy on a belt.
The chassis is serialized and modular, which is CZ's way of making the grip module swappable. The frame itself is fiberglass-reinforced polymer, 1.3 in (33 mm) wide, on a 4-inch barrel and a 7.4 in (188 mm) overall length. The SFDA trigger breaks at 25 ± 4 N (5.6 ± 0.9 lbs) and resets in 0.16 in (4 mm). Optics mount directly to the slide; the photos from CZ show Holosun, Aimpoint and Shield footprints.
No external safety here. The firing pin block, trigger safety and trigger bar safety handle drop safety, and the holster handles the rest. CZ sells the same gun with a thumb lever as the MS model.
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 bedside and the range; the version to buy if you rarely need to hide the gun.
Unlike the magazines and small parts on this site, a complete pistol has a serial number and must go through a dealer. During checkout you tell us which FFL should receive it, we ship it to them tracked, and they take care of the transfer paperwork and your state's rules at pickup. Have the dealer's details ready before you place the order.

Frequently asked questions
- Do the magazines on this site fit the DUTY 4.0?
- The listings here are for Polymer80 frame families and name the Gen 3 model they fit; the DUTY 4.0 ships with its own CZ magazines, and we do not list a cross-fit for it.
- Why buy a finished pistol instead of a build?
- A factory pistol arrives finished and serialized, with CZ's SFDA trigger and optics cut already done; a build gives you the hands-on work and parts choice. Plenty of customers want one of each.
- 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.
