Carry and duty is one lane we take seriously, and in it the new CZ DUTY 4.0 is the release of the season. CZ's new-generation striker-fired 9x19 runs on a serialized internal chassis, which leaves the fiberglass-reinforced polymer grip frame as a modular part. The slide mounts a red dot directly, fixed sights stay on, and the 4-inch barrel is unthreaded. The refined SFDA trigger breaks at 25±4 N (5.6±0.9 lbs) with 9±1 mm travel and a 4 mm reset.

Four models, two sizes. DUTY 4.0 C, compact: 15+1 standard, 17+1 on the extended base plate, 770 g, 135 mm. DUTY 4.0 F, full-size: 17+1 standard, 19+1 extended, 780 g, 143 mm. Either as a plain gun or as MS with a manual thumb safety. We ship to 48 states, so whether you are in Dallas, El Paso or Lubbock, over in Memphis and Chattanooga, down in Mobile or up in Roanoke and Greensboro, the gun goes to a dealer of your choosing. $729 MSRP, new release.

The chassis is registered and modular, which is CZ's way of making the grip module swappable. The frame itself is fiberglass-reinforced polymer, 33 mm (1.3 in) wide, on a four-inch barrel and a 188 mm (7.4 in) overall length. The SFDA trigger breaks at 25 ± 4 N (5.6 ± 0.9 lbs) and resets in 4 mm (0.16 in). Optics mount directly to the slide; the photos from CZ show Holosun, Aimpoint and Shield footprints.

Capacity on the short-grip is 15+1, with a 17+1 option through the extended base plate. Height is 135 mm (5.3 in) and the empty weight 770 g (27.2 oz). If you carry, this is the DUTY to look at; if you mostly shoot at the range, see the F.

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

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: concealed carry where your state allows it, home defense, and range time that does not need a full-frame grip.

Name any licensed dealer in your state at checkout and the DUTY 4.0 goes to them for the background check; your dealer applies your state's rules at pickup. There is no storefront on our end, the pistol moves dealer to dealer. Stock and price are re-checked against the distributor the moment you order, before anything is taken, so you are not charged on a stale listing.

Questions buyers ask: Which states can you ship the DUTY 4.0 to? We ship to dealers in 48 states. Name a licensed FFL in your state at checkout and the dealer applies local rules at pickup; if you are unsure what applies, ask them first. Is the price final when I order? Stock and price are re-checked against the distributor the moment you order, before anything is taken, so the listing you pay on is the live one. What does MS mean on the CZ DUTY 4.0 C MS? Manual safety. It adds a thumb safety lever to the firing pin block, trigger safety and trigger-bar safety that every DUTY has.
