CZ DUTY 4.0 F
Specs at a glance
About this product
Nothing goes on this site unless it is sitting on the shelf, and CZ's new DUTY 4.0 is on it now. For the customer who wants a complete, factory-serialized 9mm instead of a frame and a parts list, this is the one listing to open. It is a striker-fired 9x19mm with the serial on an internal chassis, a modular fiberglass-reinforced polymer grip frame, a slide milled for direct-mount red dots and fixed sights.
Stock covers both sizes. The C compact runs 15+1, 17+1 with the extended base plate, 770 g, 135 mm tall. The F full-size runs 17+1, 19+1 extended, 780 g, 143 mm tall. Both use a 4-inch barrel without threading, measure 188 mm long and 33 mm wide, and share the refined SFDA trigger rated 5.6±0.9 lbs with a 4 mm reset. On the MS models a manual thumb safety joins the firing pin block, trigger safety and trigger bar safety. CZ's MSRP is $729 for every version.
The F is the full-frame frame: 5.6 in (143 mm) tall, 27.7 oz (780 g) with an empty magazine, 17+1 rounds of 9mm on board and 19+1 with the extended base plate. The longer grip fills a big hand and settles the gun between shots.
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.
CZ built the DUTY around a serial-numbered chassis that the polymer grip module wraps around, the same idea that lets a owner change frame size without buying a new serial-numbered gun. The trigger is a refined SFDA striker unit, 25 ± 4 N (5.6 ± 0.9 lbs) pull, 0.16 in (4 mm) reset, 9 ± 1 mm (0.4 ± 0.04 in) travel. The slide takes optics by direct mounting; CZ's product photos show Holosun, Aimpoint and Shield units in place. Sights are fixed, the 102 mm barrel is not threaded.
Best fit: home defense, duty use, competition and long range sessions where the extra grip and two more rounds matter. Shooters coming from a CZ 75 will recognize the grip angle; owners coming from any other striker gun will notice the trigger first.
In stock means it leaves our warehouse quickly, but a complete pistol still has to go to an FFL dealer rather than to you. Pick that dealer at checkout. When the DUTY 4.0 arrives, the dealer processes the transfer and applies the handgun rules of your state at pickup. Frames and parts in the same order ship to your door the normal way.
