CZ DUTY 4.0 C MS
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.
Where the P-10 had a registered polymer frame, the DUTY 4.0 moves the serial number to an internal modular chassis. That is the headline. The rest follows the modern service-pistol formula done carefully: a striker SFDA trigger at 25 ± 4 N (5.6 ± 0.9 lbs) (0.16 in (4 mm) reset, 9 ± 1 mm (0.4 ± 0.04 in) travel), a 7.4 in (188 mm) long slide with direct-mount optics cuts, fixed sights and a 102 mm barrel without a thread.
Pick the C when the gun has to disappear under a cover garment. It gives up two rounds to the full-size model (15+1 against 17+1) and about 8 mm of grip height, and in return it is 5.3 in (135 mm) tall and 27.2 oz (770 g) light.
The MS model carries a frame-mounted manual thumb safety on top of the firing pin block, trigger safety and drawbar safety. Everything else, chassis, trigger, slide and optics cut, is the same as the version without the lever.
The CZ DUTY 4.0 C MS suits anyone who wants a modern optics-ready 9mm with CZ's grip and a trigger that is better than the class average: concealed carry where your state allows it, home defense, and range time that does not need a full-size grip.
