CZ DUTY 4.0 F MS
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.
Pick the F when the gun lives on a belt or in a bedside rather than under a T-shirt. Over the carry-size it adds two rounds (17+1 against 15+1), about 8 mm of grip and 10 g of weight, and nothing else changes.
The MS model carries a frame-mounted external safety on top of the firing pin block, trigger safety and trigger bar safety. Everything else, chassis, trigger, slide and optics cut, is the same as the version without the lever.
Under the DUTY name sits a serial-numbered 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.
Who is it for: the belt, the bedside and the range; the version to buy if you rarely need to hide the gun. If you already shoot a P-10, the DUTY is the next step in the same family, with a new chassis and the optics done right.
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.
