CZ DUTY 4.0 C MS

About this product

Range builders who finish their own frames still want one pistol that is done the day it arrives. CZ built the DUTY 4.0 for that job: a striker-fired 9x19mm with a serialized internal chassis, a fiberglass-reinforced polymer grip frame and a 4-inch barrel that is not threaded. Because the chassis carries the serial number, the grip frame is a modular part, which is a design idea anyone who works with polymer frames will recognize right away.

Pick the C compact for 15+1 rounds (17+1 with the extended base plate) at 770 g and 135 mm tall, or the F full-size for 17+1 (19+1 extended) at 780 g and 143 mm tall. Both share the 188 mm overall length, 33 mm width, fixed sights and a direct-mount optics-ready slide. MS versions add a manual thumb safety on top of the firing pin block, trigger safety and trigger bar safety. The refined SFDA trigger breaks at about 5.6 lbs with a 4 mm reset. MSRP is $729.

Capacity on the short-grip is 15+1, with a 17+1 option through the extended base plate. Height is 135 mm (5.3 in) and the empty weight 770 g (27.2 oz). If you carry, this is the DUTY to look at; if you mostly shoot at the range, see the F.

Three things define the DUTY 4.0. First, a registered modular chassis: the registered 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), 4 mm (0.16 in) 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 optic sits low without a stack of plates.

The MS model carries a frame-mounted manual thumb 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.

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.

Every DUTY 4.0 sold here is a serialized firearm, so it ships to the FFL dealer you pick at checkout rather than to your door. Your dealer runs the required paperwork and applies the rules of your state when you come in to collect it. If you are not sure which local dealer to use, choose one before you order so the transfer goes smoothly. Frames, lowers and parts from our bundles still ship direct.
