CZ DUTY 4.0 C MS
About this product
Builders on this site think in full-size terms: a 17-round grip and a long sight radius. The CZ DUTY 4.0 F is the model to compare against a finished G17-pattern build, since it also carries 17+1 rounds, or 19+1 with the extended base plate, in a fiberglass-reinforced polymer frame that stands 143 mm tall and weighs 780 g. For a shorter grip, the C compact drops to 135 mm and 770 g with 15+1, or 17+1 extended.
Both models share a serialized internal chassis, which leaves the grip frame modular, a 4-inch barrel without threading, fixed sights and an optics-ready slide for direct red dot mounting. Overall length is 188 mm, width 33 mm. The refined SFDA trigger is rated at 25 N, about 5.6 lbs, with 9 mm of travel and a 4 mm reset. Go with an MS version for a manual thumb safety joining the firing pin block, trigger safety and trigger bar safety. It is a new release from CZ with a $729 MSRP.
The C is the compact frame. It stands 5.3 in (135 mm) tall, weighs 27.2 oz (770 g) with the magazine in but empty 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.
The MS model carries a frame-mounted manual 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.
What is new under the slide is the registered modular chassis. The serial number lives on the internal chassis, not on the polymer grip, so the grip frame 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 0.16 in (4 mm) 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 reflex sights.
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: daily carry, a nightstand gun that also rides along, and new shooters who want one pistol for everything.
Frame kits ship to your door; the DUTY 4.0 ships to the FFL dealer you pick at checkout because it is a complete, serialized pistol. Your dealer completes the transfer paperwork and applies the rules of your state when you pick it up. Have the dealer's name and location ready when you order.
