CZ DUTY 4.0 F
Specs at a glance
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.
What is new under the slide is the serial-numbered 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 4 mm (0.16 in) 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 optics.
Full-size means 17+1 rounds, a grip that takes the whole hand and a frame 143 mm (5.6 in) high. With the extended floor plate the count goes to 19+1. Empty weight is 780 g (27.7 oz), which soaks up recoil without making the gun heavy on a belt.
The standard model skips the manual thumb safety and keeps the three passive ones: firing pin block, trigger safety and trigger-bar safety. Same chassis, same trigger and slide as the MS; only the lever is missing.
Best fit: the belt, the nightstand and the range; the version to buy if you rarely need to hide the gun. Shooters coming from a CZ 75 will recognize the grip angle; shooters coming from any other striker gun will notice the trigger first.
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.
