CZ DUTY 4.0 F
Specs at a glance
About this product
Iowa handgun buyers finally have a new CZ striker pistol to put on the list, and it comes in enough versions to cover carry and range duty alike. The DUTY 4.0 C is the compact at 135 mm tall, the F is the full-size at 143 mm, and each is sold plain or as an MS model with a manual thumb safety. All four share a fiberglass-reinforced polymer frame wrapped around a serialized internal chassis, which is the part that carries the number.
What stays the same across the line is the 4-inch unthreaded barrel, fixed sights, 188 mm overall length and a 33 mm width that carries well under a jacket on a cold Iowa morning. The slide is cut for a direct-mount red dot. The refined SFDA trigger measures 25±4 N, about 5.6 pounds, with a 4 mm reset. Capacity runs 15+1 in the C and 17+1 in the F, with extended base plates adding two rounds. The price CZ suggests is $729.
Pick the F when the gun lives on a belt or in a bedside rather than under a T-shirt. Over the short-grip it adds two rounds (17+1 against 15+1), about 8 mm of grip and 10 g of weight, and nothing else changes.
There is no external safety on this model. Drop safety comes from the firing pin block, the trigger safety and the trigger-bar safety, the way most modern striker-action pistols are set up. If you want a frame-mounted lever, the MS version has one.
Three things define the DUTY 4.0. First, a serial-numbered modular chassis: the serial-numbered part is inside, the frame module 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.
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.
Whether you are in Des Moines, Cedar Rapids or out of state, the pistol ships to the FFL dealer you select at checkout. That dealer handles the transfer paperwork and applies the rules of your state when you come to collect it. Pick a dealer who takes transfers and enter their details with your order, and the tracking number follows by email.
