CZ DUTY 4.0 C
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.
What is new under the slide is the registered 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 4 mm (0.16 in) 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 dot sights.
This is the shorter grip of the two DUTY frames: 135 mm (5.3 in) from the top of the slide to the base plate, 770 g (27.2 oz) empty, 15+1 rounds standard and 17+1 with the extended plate. The slide and 102 mm barrel are the same as the full-size gun, so it shoots like one.
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.
The CZ DUTY 4.0 C suits anyone who wants a modern optics-ready 9mm with CZ's grip and a trigger that is better than the class average: daily carry, a nightstand gun that also rides along, and new owners who want one pistol for everything.
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.
