CZ DUTY 4.0 F MS
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.
Full-size means 17+1 rounds, a grip that takes the whole hand and a frame 5.6 in (143 mm) high. With the extended floor plate the count goes to 19+1. Empty weight is 27.7 oz (780 g), which soaks up recoil without making the gun heavy on a belt.
Three things define the DUTY 4.0. First, a serialized modular chassis: the serialized part is inside, the grip module around it is modular. Second, the trigger, a striker SFDA rated at 25 ± 4 N (5.6 ± 0.9 lbs), 0.16 in (4 mm) reset, 9 ± 1 mm (0.4 ± 0.04 in) travel, which is short and repeatable for a service pistol. Third, a direct-mount optics-ready slide, shown by CZ with Holosun, Aimpoint and Shield dots fitted, so a reflex sight sits low without a stack of plates.
MS stands for manual thumb safety. This model adds a frame-mounted lever to the internal safeties every DUTY has: the firing pin block, the trigger safety and the trigger-bar safety. Agencies and owners who want a positive on/off control choose this version; the trigger itself is unchanged.
The CZ DUTY 4.0 F MS 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.
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.
- Is the CZ DUTY 4.0 F MS the same gun as the F?
- Yes, apart from the manual thumb safety. Chassis, trigger, slide and the 17+1 capacity are identical.
- Who should pick the MS version?
- Anyone trained on a manual safety or who wants a positive on/off control, including many agency buyers.
