CZ DUTY 4.0 F
Specs at a glance
About this product
Our pages usually start with picking a frame to match your slide. This one skips every step, because CZ ships the DUTY 4.0 assembled, serialized and ready for the range. It is a new-generation striker-fired 9x19mm offered as the C compact and the F full-size, each available with or without the MS manual thumb safety that sits alongside the firing pin block, trigger safety and trigger bar safety.
The layout still rewards someone who understands how a pistol is built. The serialized part is the internal chassis, so the fiberglass-reinforced polymer frame around it is modular. Barrel length is 4 inches with no threading, sights are fixed, and the slide is cut for a direct-mount optic. CZ lists the refined SFDA trigger at 25±4 N, about 5.6 pounds, with 9±1 mm of travel and a 4 mm reset. Capacity is 15+1 in the C and 17+1 in the F, plus two with the extended base plate. Retail is set at $729.
The chassis is serial-numbered and modular, which is CZ's way of making the polymer grip swappable. The frame itself is fiberglass-reinforced polymer, 1.3 in (33 mm) wide, on a four-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.
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 four-inch barrel as the carry-size, so the sight radius is identical; you buy the F for the grip and the extra rounds.
No manual thumb 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.
A finished firearm takes the dealer route rather than the parts route. When you check out, name the FFL dealer you want to receive it, and the pistol ships there with tracking. Your dealer handles the transfer paperwork and applies your state's rules at pickup. Sort out the dealer before you order so the box has somewhere to go.
