CZ DUTY 4.0 C MS

About this product

Drop-in triggers are a big part of what leaves our warehouse, so it is worth saying up front that CZ's new DUTY 4.0 arrives with its trigger already sorted. The refined SFDA unit is specified at 5.6±0.9 lbs, with 9 mm of travel and a 4 mm reset, and it is a factory part, not an upgrade you buy afterward. The rest of the pistol follows the same idea: a striker-fired 9x19mm built on a serialized internal chassis with a modular fiberglass-reinforced polymer grip frame, a direct-mount optics cut and fixed sights.

Sizes are simple. The C compact gives you 15+1 rounds, 17+1 with the extended base plate, in a 770 g, 135 mm tall gun. The F full-size gives you 17+1, 19+1 extended, in a 780 g, 143 mm tall gun. Both carry a 4-inch barrel without threads inside a 188 mm, 33 mm wide package. MS models add a manual thumb safety alongside the firing pin block, trigger safety and trigger bar safety. CZ lists it at $729.

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

What is new under the slide is the serialized modular chassis. The serial number lives on the internal chassis, not on the polymer grip, so the polymer grip 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 red dots.

MS stands for external safety. This model adds a frame-mounted lever to the passive safeties every DUTY has: the firing pin block, the trigger safety and the trigger-bar safety. Agencies and buyers who want a positive on/off control choose this version; the trigger itself is unchanged.

Who is it for: daily carry, a nightstand gun that also rides along, and new buyers who want one pistol for everything. 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.

Magazines and triggers from the same order ship to your address as usual, but the pistol itself ships only to an FFL dealer. Tell us which dealer at checkout. When the gun arrives there, the dealer runs the transfer and applies whatever your state requires for a handgun pickup. We leave the legal side entirely to the dealer, since they know the local rules and we do not set them.
