CZ DUTY 4.0 F
Specs at a glance
About this product
Fitment questions are most of what gets answered here, usually about which slide drops onto a PF940 frame. The CZ DUTY 4.0 raises none of them, because it arrives as a finished, factory-serialized pistol from CZ. The serial lives on an internal chassis, and the fiberglass-reinforced polymer grip frame around it is a modular part, a split frame builders will recognize.
The C compact is 135 mm tall at 770 g with 15+1 rounds, or 17+1 using the extended base plate. The F full-size is 143 mm tall at 780 g with 17+1, or 19+1 extended. Length is 188 mm and width 33 mm on both, with a 4-inch barrel that is not threaded. Sights are fixed and the slide is optics-ready for direct mounting. The refined SFDA trigger pulls around 5.6 lbs with 9 mm of travel and a 4 mm reset. MS models carry a manual thumb safety in addition to the firing pin block, trigger safety and trigger bar safety. CZ's suggested price is $729.
Capacity on the full-size is 17+1 standard and 19+1 with the extended base plate. Height 143 mm (5.6 in), empty weight 780 g (27.7 oz). It is the duty-belt, range and home-defense version of the line, and the one most owners find easiest to shoot well.
There is no manual thumb 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-fired pistols are set up. If you want a thumb lever, the MS version has one.
Three things define the DUTY 4.0. First, a registered modular chassis: the registered part is inside, the grip frame around it is modular. Second, the trigger, a striker SFDA rated at 25 ± 4 N (5.6 ± 0.9 lbs), 4 mm (0.16 in) 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 nightstand and the range; the version to buy if you rarely need to hide the gun.
Since the DUTY 4.0 is a complete serialized firearm, it cannot ship to your home like a frame or jig kit. At checkout you name an FFL dealer, the pistol ships there, and the dealer completes the transfer and applies your state's rules at pickup. Confirm the dealer accepts transfers before you order.
