CZ DUTY 4.0 C MS
About this product
Finishing a frame, fitting a slide and barrel, then testing the result takes a few evenings. CZ's DUTY 4.0 is the option for the evening you would rather spend shooting. It is a new-generation striker-fired 9x19mm, assembled and serialized at the factory, with the serial number on an internal chassis and a modular fiberglass-reinforced polymer grip frame around it. The 4-inch barrel is not threaded, the sights are fixed, and the slide is cut for a direct-mount red dot.
The compact C runs 15+1, or 17+1 with the extended base plate, at 770 g and 135 mm in height. The full-size F runs 17+1, or 19+1 extended, at 780 g and 143 mm. Both come in at 188 mm long and 33 mm wide. CZ's refined SFDA trigger pulls 25 N, around 5.6 lbs, with a 9 mm stroke and a 4 mm reset. Add the MS suffix for a manual thumb safety on top of the firing pin block, trigger safety and trigger bar safety. Suggested retail is $729.
The chassis is serial-numbered and modular, which is CZ's way of making the frame module swappable. The frame itself is fiberglass-reinforced polymer, 1.3 in (33 mm) wide, on a four-inch barrel and a 7.4 in (188 mm) overall length. The SFDA trigger breaks at 25 ± 4 N (5.6 ± 0.9 lbs) and resets in 0.16 in (4 mm). Optics mount directly to the slide; the photos from CZ show Holosun, Aimpoint and Shield footprints.
The C is the carry-size frame. It stands 5.3 in (135 mm) tall, weighs 27.2 oz (770 g) unloaded and carries 15+1 rounds of 9mm, or 17+1 once the extended base plate is fitted. Short enough to hide under a shirt, long enough to get every finger on the grip.
MS stands for manual thumb safety. This model adds a thumb lever to the internal safeties every DUTY has: the firing pin block, the trigger safety and the drawbar safety. Agencies and shooters who want a positive on/off control choose this version; the trigger itself is unchanged.
Best fit: concealed carry where your state allows it, home defense, and range time that does not need a full-frame grip. Shooters coming from a CZ 75 will recognize the grip angle; shooters coming from any other striker gun will notice the trigger first.
Because the DUTY 4.0 is a complete serialized firearm, it travels to the FFL dealer you select at checkout rather than to your address. That dealer processes the transfer paperwork and applies the rules of your state at pickup. Slides, barrels and frame kits from the rest of the store still ship direct.
