CZ DUTY 4.0 F 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.
The F is the full-frame frame: 143 mm (5.6 in) tall, 780 g (27.7 oz) with the magazine in but empty, 17+1 rounds of 9mm on board and 19+1 with the extended floor plate. The longer grip fills a big hand and settles the gun between shots.
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.
Under the DUTY name sits a serial-numbered modular chassis, a 33 mm (1.3 in) wide fiberglass-reinforced polymer frame, a four-inch barrel and a trigger CZ rates at 25 ± 4 N (5.6 ± 0.9 lbs) with a 4 mm (0.16 in) reset. The slide is optics-ready by direct mount rather than an adapter plate. Fixed sights come standard, and the barrel is not threaded.
Who is it for: the belt, the nightstand and the range; the version to buy if you rarely need to hide the gun. 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.
