CZ DUTY 4.0 C

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.

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.

This is the shorter grip of the two DUTY frames: 135 mm (5.3 in) from the top of the slide to the base plate, 770 g (27.2 oz) empty, 15+1 rounds standard and 17+1 with the extended plate. The slide and 4-inch barrel are the same as the service-size gun, so it shoots like one.

There is no manual thumb safety on this model. Drop safety comes from the firing pin block, the trigger safety and the trigger-bar safety, the way most modern striker-action pistols are set up. If you want a thumb lever, the MS version has one.

Who is it for: concealed carry where your state allows it, home defense, and range time that does not need a service-size grip. If you already shoot a P-10, the DUTY is the next step in the same family, with a new chassis and the optics done right.

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.
