CZ DUTY 4.0 F MS
About this product
Builders on this site think in full-size terms: a 17-round grip and a long sight radius. The CZ DUTY 4.0 F is the model to compare against a finished G17-pattern build, since it also carries 17+1 rounds, or 19+1 with the extended base plate, in a fiberglass-reinforced polymer frame that stands 143 mm tall and weighs 780 g. For a shorter grip, the C compact drops to 135 mm and 770 g with 15+1, or 17+1 extended.
Both models share a serialized internal chassis, which leaves the grip frame modular, a 4-inch barrel without threading, fixed sights and an optics-ready slide for direct red dot mounting. Overall length is 188 mm, width 33 mm. The refined SFDA trigger is rated at 25 N, about 5.6 lbs, with 9 mm of travel and a 4 mm reset. Go with an MS version for a manual thumb safety joining the firing pin block, trigger safety and trigger bar safety. It is a new release from CZ with a $729 MSRP.
Under the DUTY name sits a registered modular chassis, a 1.3 in (33 mm) wide fiberglass-reinforced polymer frame, a 102 mm 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.
Pick the F when the gun lives on a belt or in a nightstand rather than under a T-shirt. Over the compact it adds two rounds (17+1 against 15+1), about 8 mm of grip and 10 g of weight, and nothing else changes.
A manual 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; shooters coming from any other striker gun will notice the trigger first.
Frame kits ship to your door; the DUTY 4.0 ships to the FFL dealer you pick at checkout because it is a complete, serialized pistol. Your dealer completes the transfer paperwork and applies the rules of your state when you pick it up. Have the dealer's name and location ready when you order.
