CZ DUTY 4.0 F
Specs at a glance
About this product
Quick order is the whole idea here, and a factory pistol fits that idea better than anything. CZ's new DUTY 4.0 is one listing, four versions, no jig, no frame-fitting, no parts list to check. It is a striker-fired 9x19mm service pistol with the serial number on an internal chassis, a modular fiberglass-reinforced polymer grip frame, a direct-mount optics cut on the slide and fixed iron sights.
Read the model code and you know the gun. C is the compact, 15+1 or 17+1 with the extended base plate, 770 g and 135 mm tall. F is the full-size, 17+1 or 19+1 extended, 780 g and 143 mm tall. Add MS and a manual thumb safety joins the firing pin block, trigger safety and trigger bar safety. All four share a 4-inch unthreaded barrel, 7.4-inch overall length, 1.3-inch width and a refined SFDA trigger at about 5.6 lbs with a 4 mm reset. List price is $729 MSRP.
The F is the service-size frame: 5.6 in (143 mm) tall, 27.7 oz (780 g) with the magazine in but empty, 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.
Where the P-10 had a serialized 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 four-inch barrel without a thread.
No manual thumb safety here. The firing pin block, trigger safety and drawbar safety handle drop safety, and the holster handles the rest. CZ sells the same gun with a thumb lever as the MS model.
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; owners coming from any other striker gun will notice the trigger first.
Quick order still means one extra step for a complete firearm: a dealer. Enter your FFL's details when you order and the DUTY 4.0 ships to them, not to you. Pickup happens at the dealer, who applies the rules your state sets for handgun transfers. Frames, jigs and parts in the same cart go to your door as they always have.
