Rain or shine, the pistol that lives in a Portland nightstand or a Tillamook glovebox should be simple and tough. CZ's DUTY 4.0 is both: a fiberglass-reinforced polymer frame, a serialized modular chassis inside it, and a 4-inch barrel under a slide that is ready for a direct-mount red dot. Fixed sights come standard. The trigger is CZ's refined SFDA, rated at 5.6 pounds with 9 mm of travel and a 4 mm reset. It is a new release, striker-fired, chambered in 9x19mm.

Oregonians in Hillsboro, Oregon City, Salem, Albany and Corvallis, and out on the coast around Astoria, have four versions to choose from. The DUTY 4.0 C compact is 15+1 and 27.2 ounces; the F full-size is 17+1 and 27.5 ounces. Extended base plates add two rounds to either. The MS models bolt a manual thumb safety onto the standard firing pin block, trigger safety and trigger bar safety.

The C is the compact frame. It stands 5.3 in (135 mm) tall, weighs 27.2 oz (770 g) with an empty magazine and carries 15+1 rounds of 9mm, or 17+1 once the extended floor plate is fitted. Short enough to hide under a shirt, long enough to get every finger on the grip.

Three things define the DUTY 4.0. First, a serialized modular chassis: the serialized part is inside, the frame module 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 dot sight sits low without a stack of plates.

MS stands for manual safety. This model adds a frame-mounted lever to the automatic safeties every DUTY has: the firing pin block, the trigger safety and the trigger-bar safety. Agencies and owners who want a positive on/off control choose this version; the trigger itself is unchanged.

The CZ DUTY 4.0 C MS suits anyone who wants a modern optics-ready 9mm with CZ's grip and a trigger that is better than the class average: concealed carry where your state allows it, home defense, and range time that does not need a service-size grip.

Oregon has no permit to purchase and no fixed waiting period right now; Measure 114 is delayed and still in court, so your dealer applies whatever rules are in force the day you pick up. The DUTY 4.0 ships to the Oregon dealer you choose at checkout. Ammo and gear ship to your door. Everything is price- and stock-checked live before you pay.

Questions buyers ask: Do I need a permit to buy a handgun in Oregon right now? Not today. Oregon has no permit to purchase and no fixed waiting period at present, but Measure 114 is still in court, so your dealer will confirm the current rules at pickup. Is the DUTY 4.0 barrel threaded? No. It is a 4-inch unthreaded barrel on every model, C and F, with or without the manual safety. What does MS mean on the CZ DUTY 4.0 C MS? Manual safety. It adds a frame-mounted lever to the firing pin block, trigger safety and trigger-bar safety that every DUTY has.
