CZ DUTY 4.0 F 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.

The chassis is serial-numbered and modular, which is CZ's way of making the grip frame swappable. The frame itself is fiberglass-reinforced polymer, 1.3 in (33 mm) wide, on a 102 mm 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.

Capacity on the service-size is 17+1 standard and 19+1 with the extended base plate. Height 5.6 in (143 mm), empty weight 27.7 oz (780 g). It is the duty-belt, range and home-defense version of the line, and the one most owners find easiest to shoot well.

MS stands for manual thumb safety. This model adds a thumb safety lever to the automatic safeties every DUTY has: the firing pin block, the trigger safety and the drawbar safety. Agencies and owners who want a positive on/off control choose this version; the trigger itself is unchanged.

Best fit: home defense, duty use, competition and long range sessions where the extra grip and two more rounds matter. Shooters coming from a CZ 75 will recognize the grip angle; owners coming from any other striker gun will notice the trigger first.

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.
