CZ DUTY 4.0 F MS
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.
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.
This is the longer grip of the two DUTY frames. It holds 17+1 rounds, 19+1 with the extended plate, stands 5.6 in (143 mm) and weighs 27.7 oz (780 g) unloaded. Same slide, same 4-inch barrel as the short-grip, so the sight radius is identical; you buy the F for the grip and the extra rounds.
A external 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.
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; buyers coming from any other striker gun will notice the trigger first.
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.
