Four pistols, one new CZ platform. The DUTY 4.0 comes as the C compact and the F full-size, and each is offered with or without a manual thumb safety, the MS versions. All four are striker-fired 9x19mm guns with a 4-inch barrel, fixed sights and a slide cut for direct-mount red dots. The part that carries the serial number is the internal chassis, so the polymer grip frame around it is a module, not the gun itself.

For buyers from Oregon to Georgia this is the kind of pistol that does several jobs at once: a first handgun that will not be outgrown, a nightstand gun that holds 15 or 17 rounds, a range gun with a crisp 5.6-pound trigger, or a carry pistol where your state permits it. At a $729 MSRP it lands squarely in the service-pistol bracket, and it ships to any FFL dealer in the country.

This is the longer grip of the two DUTY frames. It holds 17+1 rounds, 19+1 with the extended plate, stands 5.6 in (143 mm) and weighs 27.7 oz (780 g) unloaded. Same slide, same 102 mm barrel as the short-grip, so the sight radius is identical; you buy the F for the grip and the extra rounds.

The MS model carries a frame-mounted manual safety on top of the firing pin block, trigger safety and trigger-bar safety. Everything else, chassis, trigger, slide and optics cut, is the same as the version without the lever.

Three things define the DUTY 4.0. First, a serialized modular chassis: the serialized part is inside, the polymer grip around it is modular. Second, the trigger, a striker SFDA rated at 25 ± 4 N (5.6 ± 0.9 lbs), 0.16 in (4 mm) reset, 9 ± 1 mm (0.4 ± 0.04 in) travel, which is short and repeatable for a service pistol. Third, a direct-mount optics-ready slide, shown by CZ with Holosun, Aimpoint and Shield dots fitted, so a red dot sits low without a stack of plates.

The CZ DUTY 4.0 F MS 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.

Pick the model, then name the licensed dealer you want it sent to. We ship to FFL dealers nationwide, and your dealer applies your state's law at pickup, whatever that means where you live. Ammo and gear ship to your door where legal. Price and stock are confirmed live when you order, before you pay, so there is no surprise after the fact.

Questions buyers ask: Which DUTY 4.0 should a first-time buyer pick? The F full-size gives you 17+1 rounds and a slightly taller grip for the range or the nightstand; the C compact holds 15+1 and is about 8 mm shorter, which matters more if you plan to carry. Both share the same barrel, trigger and slide length. Can I put a red dot on it myself? Yes. The slide is optics-ready with direct-mount cuts, and CZ's own photos show Holosun, Aimpoint and Shield dots fitted. The fixed iron sights stay on either way. Is the CZ DUTY 4.0 F MS the same gun as the F? Yes, apart from the manual thumb safety. Chassis, trigger, slide and the 17+1 capacity are identical.
