CZ DUTY 4.0 F
Specs at a glance
About this product
Some customers want to build; some want to open a box and go shooting. For the second group, CZ's new DUTY 4.0 lands beside our ready-made pistols as a factory-assembled, factory-serialized 9mm with nothing left to finish. It is a striker-fired 9x19mm with a fiberglass-reinforced polymer grip frame that is modular, because the serial number lives on the internal chassis. The slide is milled for direct-mount red dots; CZ's photos show Holosun, Aimpoint and Shield units fitted.
Choose C for a compact that holds 15+1, or 17+1 with the extended base plate, at 770 g and 135 mm tall. Choose F for a full-size that holds 17+1, 19+1 extended, at 780 g and 143 mm. Both have a 4-inch unthreaded barrel, 7.4-inch overall length, fixed sights and a refined SFDA trigger at roughly 5.6 lbs with a 4 mm reset. The MS versions add a manual thumb safety for shooters who want a lever. Suggested retail from CZ: $729.
Pick the F when the gun lives on a belt or in a bedside rather than under a T-shirt. Over the carry-size it adds two rounds (17+1 against 15+1), about 8 mm of grip and 10 g of weight, and nothing else changes.
No manual 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 frame-mounted lever as the MS model.
Three things define the DUTY 4.0. First, a registered modular chassis: the registered part is inside, the polymer grip around it is modular. Second, the trigger, a striker SFDA rated at 25 ± 4 N (5.6 ± 0.9 lbs), 0.16 in (4 mm) reset, 9 ± 1 mm (0.4 ± 0.04 in) travel, which is short and repeatable for a service pistol. Third, a direct-mount optics-ready slide, shown by CZ with Holosun, Aimpoint and Shield dots fitted, so a dot sight sits low without a stack of plates.
Best fit: home defense, duty use, competition and long range sessions where the extra grip and two more rounds matter. Shooters coming from a CZ 75 will recognize the grip angle; owners coming from any other striker gun will notice the trigger first.
Kits and parts go to your door; a complete pistol like this one goes to your FFL. At checkout, name the dealer who will receive it, and we ship the DUTY 4.0 to them. The dealer finishes the transfer and applies the rules of your state when you come in to collect it. If you have never used a dealer for a transfer before, any FFL that accepts inbound handguns can do it.
