CZ DUTY 4.0 F
Specs at a glance
About this product
Slides and barrels fill most of our catalog, which makes a pistol that arrives with both already fitted an easy thing to explain. CZ's DUTY 4.0 is a new-generation striker-fired 9mm with a serialized internal chassis, a modular fiberglass-reinforced polymer grip frame, a 4-inch barrel without threads and fixed sights. The slide is cut for a direct-mount red dot, and CZ's own photos show Holosun, Aimpoint and Shield optics on it.
Pick the C compact for 15+1 and a 135 mm height, or the F full-size for 17+1 and 143 mm; either gains two rounds with the extended base plate. Add MS to the model and you get a manual thumb safety on top of the firing pin block, trigger safety and trigger bar safety. The refined SFDA trigger is rated at 25±4 N with a 4 mm reset and 9±1 mm of travel. Overall length is 188 mm, width 33 mm, and CZ's suggested price is $729.
Full-size means 17+1 rounds, a grip that takes the whole hand and a frame 5.6 in (143 mm) high. With the extended floor plate the count goes to 19+1. Empty weight is 27.7 oz (780 g), which soaks up recoil without making the gun heavy on a belt.
This version has no external safety lever. It relies on three internal safeties, firing pin block, trigger safety and trigger-bar safety, and the trigger is the same as on the MS model. Shooters who prefer a lever should pick the MS.
What is new under the slide is the serialized modular chassis. The serial number lives on the internal chassis, not on the polymer grip, so the polymer grip 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 red dots.
Best fit: the belt, the home-defense and the range; the version to buy if you rarely need to hide the gun. Shooters coming from a CZ 75 will recognize the grip angle; owners coming from any other striker gun will notice the trigger first.
Parts ship to your door; a complete pistol does not. When you order the DUTY 4.0, choose the FFL dealer who will receive it, and we send it there with tracking. The dealer completes the transfer paperwork and applies the rules of your state at pickup. Pick a dealer who takes transfers and have their details ready before you check out.
