CZ DUTY 4.0 C MS
About this product
Not every customer who shops frame parts wants to finish a frame. For the buyer who would rather pick up a serialized, factory-built service pistol and go shoot, we added CZ's new DUTY 4.0 in all four versions: C compact, F full-size, and the MS variants of each with a manual thumb safety. It is a striker-fired 9x19mm with a fiberglass-reinforced polymer frame, a 4-inch barrel and fixed sights.
The design will look familiar to anyone who studies how pistols are put together. CZ serialized the internal chassis rather than the grip, so the frame around it is a modular component. The slide is machined for direct-mount red dots, and CZ photographs it wearing Holosun, Aimpoint and Shield units. Trigger pull is 25±4 N, and the 4 mm reset is the number that will stand out to anyone who tunes triggers. The C carries 15+1 and the F 17+1, both gaining two rounds with the extended base plate. CZ's MSRP is $729.
Capacity on the compact is 15+1, with a 17+1 option through the extended base plate. Height is 5.3 in (135 mm) and the empty weight 27.2 oz (770 g). If you carry, this is the DUTY to look at; if you mostly shoot at the range, see the F.
CZ built the DUTY around a serialized chassis that the polymer grip module wraps around, the same idea that lets a shooter change frame size without buying a new serialized gun. The trigger is a refined SFDA striker unit, 25 ± 4 N (5.6 ± 0.9 lbs) pull, 0.16 in (4 mm) reset, 9 ± 1 mm (0.4 ± 0.04 in) travel. The slide takes optics by direct mounting; CZ's product photos show Holosun, Aimpoint and Shield units in place. Sights are fixed, the 4-inch barrel is not threaded.
This is the version with a manual thumb safety. The three automatic safeties (firing pin block, trigger safety, trigger bar safety) are the same as on every DUTY; the lever is an extra for people who were trained on one or simply want one.
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 full-size grip.
Unlike the magazines and small parts on this site, a complete pistol has a serial number and must go through a dealer. During checkout you tell us which FFL should receive it, we ship it to them tracked, and they take care of the transfer paperwork and your state's rules at pickup. Have the dealer's details ready before you place the order.

Frequently asked questions
- Do the magazines on this site fit the DUTY 4.0?
- The listings here are for Polymer80 frame families and name the Gen 3 model they fit; the DUTY 4.0 ships with its own CZ magazines, and we do not list a cross-fit for it.
- Why buy a finished pistol instead of a build?
- A factory pistol arrives finished and serialized, with CZ's SFDA trigger and optics cut already done; a build gives you the hands-on work and parts choice. Plenty of customers want one of each.
- What does MS mean on the CZ DUTY 4.0 C MS?
- Manual safety. It adds a thumb lever to the firing pin block, trigger safety and trigger bar safety that every DUTY has.
- Does the manual safety change the trigger?
- No. CZ rates the trigger the same on both versions: 5.6 pounds with a 4 mm reset.
