CZ DUTY 4.0 F MS
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.
The chassis is registered and modular, which is CZ's way of making the grip module swappable. The frame itself is fiberglass-reinforced polymer, 33 mm (1.3 in) wide, on a 102 mm barrel and a 188 mm (7.4 in) overall length. The SFDA trigger breaks at 25 ± 4 N (5.6 ± 0.9 lbs) and resets in 4 mm (0.16 in). Optics mount directly to the slide; the photos from CZ show Holosun, Aimpoint and Shield footprints.
Pick the F when the gun lives on a belt or in a bedside rather than under a T-shirt. Over the compact it adds two rounds (17+1 against 15+1), about 8 mm of grip and 10 g of weight, and nothing else changes.
MS stands for manual safety. This model adds a thumb lever to the internal safeties every DUTY has: the firing pin block, the trigger safety and the trigger-bar safety. Agencies and shooters who want a positive on/off control choose this version; the trigger itself is unchanged.
Best fit: the belt, the bedside and the range; the version to buy if you rarely need to hide the gun. Shooters coming from a CZ 75 will recognize the grip angle; shooters coming from any other striker gun will notice the trigger first.
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.
