CZ DUTY 4.0 F
Specs at a glance
About this product
Our notes on CZ's new DUTY 4.0 come from the factory spec sheet rather than a range day, since the pistol is a fresh release, so read them as a reader's guide and not a verdict. The headline is the construction: a striker-fired 9x19mm where the serialized component is an internal chassis and the fiberglass-reinforced polymer grip frame is modular. The slide takes direct-mount optics, with Holosun, Aimpoint and Shield dots shown in CZ's photos, and fixed sights are included.
Note two: the trigger. CZ calls it a refined SFDA and specifies 25±4 N, about 5.6 lbs, with 9±1 mm of travel and a 4 mm reset. Note three: the sizes. C compact is 15+1 or 17+1 extended, 770 g, 135 mm tall; F full-size is 17+1 or 19+1 extended, 780 g, 143 mm tall. Both use a 4-inch unthreaded barrel in a 188 mm, 33 mm wide body. Note four: MS adds a manual thumb safety. Note five: MSRP $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 longer base 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.
There is no manual thumb safety on this model. Drop safety comes from the firing pin block, the trigger safety and the drawbar 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 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.
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; shooters coming from any other striker gun will notice the trigger first.
