CZ DUTY 4.0 F
Specs at a glance
About this product
Across Kansas, a 9mm that rides in a truck console all week and goes to the range on Saturday needs to be simple and tough. CZ's new DUTY 4.0 fits that life. It is a striker-fired 9x19mm with a fiberglass-reinforced polymer frame and a serialized internal chassis, so the grip frame is a modular part. The barrel is 4 inches and not threaded, the sights are fixed, and the slide takes a red dot by direct mount.
Kansas shooters who want a belt gun will lean toward the C compact: 15+1 rounds, 17+1 with the extended base plate, 770 g and 135 mm tall. Those who want a full grip for the range will prefer the F full-size: 17+1, 19+1 extended, 780 g and 143 mm tall. Either one measures 188 mm long by 33 mm wide. Trigger pull is about 5.6 lbs, reset 4 mm. Order the MS version if you want a manual thumb safety added to the three internal safeties. MSRP is $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) (4 mm (0.16 in) reset, 9 ± 1 mm (0.4 ± 0.04 in) travel), a 188 mm (7.4 in) 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 143 mm (5.6 in) high. With the extended base plate the count goes to 19+1. Empty weight is 780 g (27.7 oz), which soaks up recoil without making the gun heavy on a belt.
This version has no external safety lever. It relies on three internal safeties, firing pin block, trigger safety and trigger-bar safety, and the trigger is the same as on the MS model. Shooters who prefer a lever should pick the MS.
The CZ DUTY 4.0 F suits anyone who wants a modern optics-ready 9mm with CZ's grip and a trigger that is better than the class average: home defense, duty use, competition and long range sessions where the extra grip and two more rounds matter.
Your DUTY 4.0 ships to the Kansas FFL dealer you choose at checkout, or to a dealer in another state if you live elsewhere. That dealer does the transfer paperwork and applies the rules of that state at pickup. We do not ship complete pistols to a home address. Choose your dealer before ordering so the pistol has a clear destination.
