CZ DUTY 4.0 F
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.
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 102 mm barrel as the compact, so the sight radius is identical; you buy the F for the grip and the extra rounds.
There is no manual thumb safety on this model. Drop safety comes from the firing pin block, the trigger safety and the drawbar safety, the way most modern striker pistols are set up. If you want a thumb safety lever, the MS version has one.
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 grip frame 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 0.16 in (4 mm) 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 optics.
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: home defense, duty use, competition and long range sessions where the extra grip and two more rounds matter.
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.
