CZ DUTY 4.0 F
Specs at a glance
About this product
Speed is the reason people shop this site, and a factory pistol is the fastest route to a finished 9mm. CZ's new DUTY 4.0 is a striker-fired service gun with a serialized internal chassis, a fiberglass-reinforced polymer frame that is modular around that chassis, a 4-inch unthreaded barrel and fixed sights. Choose the C compact or the F full-size, and add MS to the name if you want a manual thumb safety on top of the internal safeties.
The two sizes are near twins from the front. Each is 188 mm long and 33 mm wide; the C is 135 mm tall at 770 grams and the F is 143 mm at 780 grams. Magazine capacity is 15+1 or 17+1 respectively, and the extended base plate adds two rounds to either. The slide takes a direct-mount red dot. CZ rates the SFDA trigger at 25±4 N with a 4 mm reset. The suggested price is $729.
Under the DUTY name sits a serialized modular chassis, a 1.3 in (33 mm) wide fiberglass-reinforced polymer frame, a four-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 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 floor plate. The longer grip fills a big hand and settles the gun between shots.
No manual thumb safety here. The firing pin block, trigger safety and trigger-bar safety handle drop safety, and the holster handles the rest. CZ sells the same gun with a frame-mounted lever as the MS model.
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.
A serialized pistol cannot leave the warehouse addressed to a home. It ships tracked to the FFL dealer you pick at checkout, and the dealer handles the transfer paperwork and applies the rules of your state when you collect it. Pickup timing depends on your dealer's schedule, so line one up and enter their details before you place the order.

Frequently asked questions
- Does the pistol ship as fast as parts orders?
- It leaves on the same schedule as the rest of the warehouse, but it goes to your FFL dealer rather than your door, so add the dealer's own handling time.
- What does 25±4 N mean on the trigger spec?
- That is CZ's pull weight in newtons, which works out to about 5.6 pounds give or take 0.9; reset is 4 mm and total travel about 9 mm.
- How many rounds does the CZ DUTY 4.0 F hold?
- 17+1 with the standard magazine and 19+1 with the extended base plate.
- Can I put a red dot on it?
- Yes. The slide is optics-ready with direct mounting; CZ's photos show Holosun, Aimpoint and Shield dots fitted.
