CZ DUTY 4.0 C MS

About this product

Builders who have finished a few Gen 3-pattern frames sometimes want one pistol in the safe that came out of a factory box with the serial already on it. CZ's new DUTY 4.0 is our pick for that slot. It is a striker-fired 9x19mm built the chassis way: the serialized part is an internal chassis, and the fiberglass-reinforced polymer grip frame around it is modular. The slide is cut for direct-mount optics, with fixed sights standard.

Capacity depends on the size you pick. The C compact loads 15+1, or 17+1 once the extended base plate goes on, and weighs 770 g at 135 mm tall. The F full-size loads 17+1, 19+1 extended, and weighs 780 g at 143 mm tall. Both carry a 4-inch barrel with no threads and use a refined SFDA trigger at about 5.6 lbs with a 4 mm reset. Order the MS variant if you want a manual thumb safety too. CZ puts MSRP at $729.

What is new under the slide is the serial-numbered modular chassis. The serial number lives on the internal chassis, not on the polymer grip, so the frame module is a part you can change while the gun stays the same gun. Around it CZ put a reworked SFDA striker trigger, rated at 25 ± 4 N (5.6 ± 0.9 lbs) with a 4 mm (0.16 in) reset and 9 ± 1 mm (0.4 ± 0.04 in) of travel, and a slide cut for direct-mount optics. CZ's own photos show it wearing Holosun, Aimpoint and Shield red dots.

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 four-inch barrel are the same as the full-frame gun, so it shoots like one.

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.

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; buyers coming from any other striker gun will notice the trigger first.

Because this one arrives serialized, it ships to your FFL dealer instead of your house. Name the dealer at checkout. The dealer completes the paperwork and applies the rules of the state where you pick the pistol up, whatever those are; we do not add conditions of our own. Frames and parts ordered alongside it still ship to your door.
