CZ DUTY 4.0 F
Specs at a glance
About this product
Builders on this site think in full-size terms: a 17-round grip and a long sight radius. The CZ DUTY 4.0 F is the model to compare against a finished G17-pattern build, since it also carries 17+1 rounds, or 19+1 with the extended base plate, in a fiberglass-reinforced polymer frame that stands 143 mm tall and weighs 780 g. For a shorter grip, the C compact drops to 135 mm and 770 g with 15+1, or 17+1 extended.
Both models share a serialized internal chassis, which leaves the grip frame modular, a 4-inch barrel without threading, fixed sights and an optics-ready slide for direct red dot mounting. Overall length is 188 mm, width 33 mm. The refined SFDA trigger is rated at 25 N, about 5.6 lbs, with 9 mm of travel and a 4 mm reset. Go with an MS version for a manual thumb safety joining the firing pin block, trigger safety and trigger bar safety. It is a new release from CZ with a $729 MSRP.
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.
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 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.
No manual safety here. The firing pin block, trigger safety and trigger bar 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; shooters coming from any other striker gun will notice the trigger first.
Frame kits ship to your door; the DUTY 4.0 ships to the FFL dealer you pick at checkout because it is a complete, serialized pistol. Your dealer completes the transfer paperwork and applies the rules of your state when you pick it up. Have the dealer's name and location ready when you order.
