CZ DUTY 4.0 C
Specs at a glance
About this product
Matching a slide to a frame to a barrel is most of what we do, and with CZ's new DUTY 4.0 that matching is done at the factory. The slide is already milled for direct-mount red dots and wears fixed sights; the 4-inch unthreaded barrel is already fitted; the fiberglass-reinforced polymer grip frame is a modular part because the serial number sits on an internal chassis. It is a striker-fired 9x19mm, and it is new this season.
Size and safety are the only choices. C compact gives 15+1, 17+1 with the extended base plate, at 770 g and 135 mm tall. F full-size gives 17+1, 19+1 extended, at 780 g and 143 mm tall. Overall length is 188 mm and width 33 mm on both. The refined SFDA trigger is rated 25±4 N, about 5.6 lbs, with a 4 mm reset. Order an MS model for a manual thumb safety alongside the firing pin block, trigger safety and trigger bar safety. The factory price tag reads $729 MSRP.
Compact means 15+1 rounds in a frame 5.3 in (135 mm) high. Fit the extended base plate and it holds 17+1. At 27.2 oz (770 g) unloaded it sits between a pocket pistol and a service-size gun, which is exactly where a carry-and-home-defense 9mm belongs.
CZ built the DUTY around a serial-numbered chassis that the polymer grip frame 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, 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 102 mm barrel is not threaded.
No manual thumb safety here. The firing pin block, trigger safety and drawbar safety handle drop safety, and the holster handles the rest. CZ sells the same gun with a thumb safety lever as the MS model.
Best fit: daily carry, a home-defense gun that also rides along, and new owners who want one pistol for everything. Shooters coming from a CZ 75 will recognize the grip angle; owners coming from any other striker gun will notice the trigger first.
A complete pistol cannot ship to your door the way a slide or frame does, so the DUTY 4.0 goes to the FFL dealer you name at checkout. That dealer completes the transfer and applies your state's handgun rules at the counter. Keep the dealer's details handy when you order; everything else in the cart ships to your address as usual.

Frequently asked questions
- Can I swap the DUTY 4.0 slide onto one of the frames sold here?
- No. The DUTY 4.0 is its own platform, and nothing on this site other than the DUTY 4.0 itself is made to fit it.
- What capacity does the DUTY 4.0 come with?
- 15+1 for the C and 17+1 for the F as standard; extended base plates take them to 17+1 and 19+1.
- Does the CZ DUTY 4.0 C take CZ P-10 magazines?
- CZ lists the DUTY with its own 15-round magazine and an extended base plate for 17+1. P-10 magazine fit is not confirmed, so plan on DUTY magazines.
- Is the compact easy to shoot?
- It shares the 4-inch barrel and slide with the full-size gun, so the sight radius is the same. Only the grip is shorter.
