CZ DUTY 4.0 C MS
About this product
Builders who finish lowers by the pack usually keep one factory pistol around as a known reference. For a modern striker-fired 9x19mm, CZ's new DUTY 4.0 makes a good one. Its serial number is on an internal chassis, which leaves the fiberglass-reinforced polymer grip frame as a modular part. The barrel is 4 inches and not threaded, the sights are fixed, and the slide is optics-ready for direct mounting.
Specs by model: the C compact is 135 mm tall, weighs 770 g and holds 15+1, or 17+1 with the extended base plate; the F full-size is 143 mm tall, weighs 780 g and holds 17+1, or 19+1 extended. Shared numbers: 188 mm long, 33 mm wide. The refined SFDA trigger is specified at 25 plus or minus 4 N, about 5.6 lbs, with 9 mm of travel and a 4 mm reset. Pick an MS model for a manual thumb safety in addition to the firing pin block, trigger safety and trigger bar safety. MSRP is $729 per pistol.
Three things define the DUTY 4.0. First, a serial-numbered modular chassis: the serial-numbered part is inside, the polymer grip around it is modular. Second, the trigger, a striker SFDA rated at 25 ± 4 N (5.6 ± 0.9 lbs), 4 mm (0.16 in) reset, 9 ± 1 mm (0.4 ± 0.04 in) travel, which is short and repeatable for a service pistol. Third, a direct-mount optics-ready slide, shown by CZ with Holosun, Aimpoint and Shield dots fitted, so a optic sits low without a stack of plates.
Capacity on the short-grip is 15+1, with a 17+1 option through the extended floor 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.
The MS model carries a frame-mounted manual thumb 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.
Who is it for: concealed carry where your state allows it, home defense, and range time that does not need a full-frame 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.
Packs of lowers ship direct, but each DUTY 4.0 is a serialized complete firearm and ships to the FFL dealer you select at checkout. At pickup the dealer runs the transfer paperwork and applies your state's rules. If you order more than one, they all go to the same dealer you name.
