CZ DUTY 4.0 F
Specs at a glance
About this product
Numbers first, since that is how this catalog's readers shop. CZ's new DUTY 4.0 runs a refined SFDA trigger specified at 25±4 N, which works out to 5.6±0.9 lbs, with 9±1 mm of travel and a 4 mm reset. The barrel is 102 mm (4 in) and unthreaded. Overall length is 188 mm, width 33 mm. The slide is cut for direct-mount optics with no plate stack in between, and fixed sights are fitted from the factory.
What makes it a new generation rather than a facelift is the frame layout. The serialized part is an internal chassis; the fiberglass-reinforced polymer grip around it is modular. The C compact (15+1, 17+1 with extended base plate, 770 g, 135 mm) and the F full-size (17+1, 19+1 extended, 780 g, 143 mm) share that chassis concept. MS models stack a manual thumb safety on top of the firing pin block, trigger safety and trigger bar safety. CZ's MSRP is $729.
Pick the F when the gun lives on a belt or in a nightstand rather than under a T-shirt. Over the short-grip it adds two rounds (17+1 against 15+1), about 8 mm of grip and 10 g of weight, and nothing else changes.
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.
Under the DUTY name sits a serialized modular chassis, a 1.3 in (33 mm) wide fiberglass-reinforced polymer frame, a 4-inch barrel and a trigger CZ rates at 25 ± 4 N (5.6 ± 0.9 lbs) with a 0.16 in (4 mm) reset. The slide is optics-ready by direct mount rather than an adapter plate. Fixed sights come standard, and the barrel is not threaded.
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: home defense, duty use, competition and long range sessions where the extra grip and two more rounds matter.
As with every serialized item in this catalog, the DUTY 4.0 is shipped to an FFL dealer of your choosing rather than to a residence. That dealer carries out the transfer and applies the regulations of the state where you take possession. Select a dealer you trust at checkout; if you are unsure whether they accept inbound handguns, confirm with them before placing the order.
