CZ DUTY 4.0 F
Specs at a glance
About this product
Builders and non-builders both shop here, and this listing is for the second group, or the first group on a day when they want a gun that is already done. CZ's DUTY 4.0 is a new striker-fired 9mm sold in four forms: the C compact, the F full-size, and MS versions of each that add a manual thumb safety. The number is on the internal chassis, so the fiberglass-reinforced polymer frame is a modular piece around it.
Compare it to a finished build and the specs hold up. A 4-inch barrel, fixed sights, 188 mm overall and 33 mm across the slide. The optics cut is direct-mount, and CZ's own images show Holosun, Aimpoint and Shield dots sitting on it. The SFDA trigger pulls about 5.6 pounds with a 4 mm reset and 9 mm of travel. Capacity is 15+1 for the C and 17+1 for the F, with extended base plates adding two rounds. MSRP for the new release is $729.
What is new under the slide is the registered modular chassis. The serial number lives on the internal chassis, not on the polymer grip, so the grip frame 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 reflex sights.
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 external 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.
The CZ DUTY 4.0 F suits anyone who wants a modern optics-ready 9mm with CZ's grip and a trigger that is better than the class average: the belt, the home-defense and the range; the version to buy if you rarely need to hide the gun.
Like every factory firearm on this site, the DUTY 4.0 goes to an FFL dealer rather than to your house. Name the dealer at checkout, and we ship the pistol there with tracking. The dealer runs the transfer paperwork and applies whatever your state requires at pickup. If you have not used a dealer for a transfer before, confirm they accept them before ordering.
