CZ DUTY 4.0 F 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.
The F is the full-size frame: 5.6 in (143 mm) tall, 27.7 oz (780 g) with an empty magazine, 17+1 rounds of 9mm on board and 19+1 with the longer base plate. The longer grip fills a big hand and settles the gun between shots.
MS stands for manual thumb safety. This model adds a thumb lever to the automatic safeties every DUTY has: the firing pin block, the trigger safety and the drawbar safety. Agencies and shooters who want a positive on/off control choose this version; the trigger itself is unchanged.
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.
