CZ DUTY 4.0 C MS

About this product

Matching a slide to a frame to a barrel is most of what we do, and with CZ's new DUTY 4.0 that matching is done at the factory. The slide is already milled for direct-mount red dots and wears fixed sights; the 4-inch unthreaded barrel is already fitted; the fiberglass-reinforced polymer grip frame is a modular part because the serial number sits on an internal chassis. It is a striker-fired 9x19mm, and it is new this season.

Size and safety are the only choices. C compact gives 15+1, 17+1 with the extended base plate, at 770 g and 135 mm tall. F full-size gives 17+1, 19+1 extended, at 780 g and 143 mm tall. Overall length is 188 mm and width 33 mm on both. The refined SFDA trigger is rated 25±4 N, about 5.6 lbs, with a 4 mm reset. Order an MS model for a manual thumb safety alongside the firing pin block, trigger safety and trigger bar safety. The factory price tag reads $729 MSRP.

This is the shorter grip of the two DUTY frames: 5.3 in (135 mm) from the top of the slide to the base plate, 27.2 oz (770 g) empty, 15+1 rounds standard and 17+1 with the extended plate. The slide and 102 mm barrel are the same as the service-size gun, so it shoots like one.

A manual thumb safety is the one thing that separates this model from its sibling. It sits beside the three automatic safeties, firing pin block, trigger safety and drawbar safety, and does not change the trigger pull.

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 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 optics.

Who is it for: concealed carry where your state allows it, home defense, and range time that does not need a service-size 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.

A complete pistol cannot ship to your door the way a slide or frame does, so the DUTY 4.0 goes to the FFL dealer you name at checkout. That dealer completes the transfer and applies your state's handgun rules at the counter. Keep the dealer's details handy when you order; everything else in the cart ships to your address as usual.
