CZ DUTY 4.0 C
Specs at a glance
About this product
Anyone who has milled a PF940 rail block will look at the DUTY 4.0 and notice where CZ put the serial number: on an internal chassis, not on the polymer. That single choice makes the fiberglass-reinforced grip frame a modular part and gives the pistol a layout that frame-first people will appreciate. The rest is a modern striker-fired 9x19mm with a 4-inch barrel, no threading, and fixed sights.
Sizes break down this way. C compact: 15+1 rounds, 17+1 with the extended base plate, 770 g, 135 mm tall. F full-size: 17+1, 19+1 extended, 780 g, 143 mm tall. Shared dimensions are 188 mm long and 33 mm wide. The optics-ready slide accepts a red dot by direct mount, and CZ's press photos show Holosun, Aimpoint and Shield units fitted. Trigger is a refined SFDA at 25 N, about 5.6 lbs, 9 mm travel, 4 mm reset. The MS suffix means a manual thumb safety sits alongside the firing pin block, trigger safety and trigger bar safety. MSRP: $729.
Compact means 15+1 rounds in a frame 135 mm (5.3 in) high. Fit the extended base plate and it holds 17+1. At 770 g (27.2 oz) unloaded it sits between a pocket pistol and a full-frame gun, which is exactly where a carry-and-home-defense 9mm belongs.
Where the P-10 had a registered polymer frame, the DUTY 4.0 moves the serial number to an internal modular chassis. That is the headline. The rest follows the modern service-pistol formula done carefully: a striker SFDA trigger at 25 ± 4 N (5.6 ± 0.9 lbs) (4 mm (0.16 in) reset, 9 ± 1 mm (0.4 ± 0.04 in) travel), a 188 mm (7.4 in) long slide with direct-mount optics cuts, fixed sights and a 4-inch barrel without a thread.
The standard model skips the manual safety and keeps the three passive ones: firing pin block, trigger safety and drawbar safety. Same chassis, same trigger and slide as the MS; only the lever is missing.
Who is it for: concealed carry where your state allows it, home defense, and range time that does not need a full-frame 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.
Unlike the frame kits here, a DUTY 4.0 is a serialized complete pistol and must go through an FFL dealer. Select your dealer at checkout, the pistol goes to that dealer, and the dealer completes the transfer and applies your state's rules when you come to collect it. Make sure the dealer is expecting it.

Frequently asked questions
- Can the grip frame on the DUTY 4.0 be changed?
- The grip frame is a modular polymer part because the serial number sits on the internal chassis. The chassis is the regulated component.
- What is the weight difference between the C and the F?
- Only 10 g: the C compact weighs 770 g and the F full-size 780 g. The main difference is the 8 mm of extra grip height and two more rounds in the F.
- Does the CZ DUTY 4.0 C take CZ P-10 magazines?
- CZ lists the DUTY with its own 15-round magazine and an extended base plate for 17+1. P-10 magazine fit is not confirmed, so plan on DUTY magazines.
- Is the compact easy to shoot?
- It shares the 4-inch barrel and slide with the full-size gun, so the sight radius is the same. Only the grip is shorter.
