CZ DUTY 4.0 F MS
About this product
Value shoppers want the full spec before the price, so here it is in one place. CZ's DUTY 4.0 is a new striker-fired 9x19mm with a serialized internal chassis, a modular fiberglass-reinforced polymer frame, a 4-inch unthreaded barrel and fixed sights. It is sold as the C compact or the F full-size, and each comes plain or as an MS model with a manual thumb safety added to the internal safeties.
What you get for an MSRP of $729 is a direct-mount optics-ready slide that CZ shows carrying Holosun, Aimpoint and Shield dots, and a refined SFDA trigger rated at 25±4 N with 9±1 mm of travel and a 4 mm reset. The compact runs 15+1 and the full-size 17+1; the extended base plate adds two rounds to either. Both are 188 mm long and 33 mm wide, with the C at 770 grams and the F at 780. For a customer finishing lowers in bulk, it is a complete pistol to shoot while the projects wait.
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.
Full-size means 17+1 rounds, a grip that takes the whole hand and a frame 5.6 in (143 mm) high. With the longer base 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.
The MS model carries a frame-mounted manual thumb 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.
Who is it for: home defense, duty use, competition and long range sessions where the extra grip and two more rounds matter. 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.
This is a serialized firearm, so it will not ship to a home address like a multi-pack of lowers. Choose the FFL dealer who should receive it when you check out, and the pistol goes to them tracked. That dealer completes the transfer paperwork and applies the rules of your state at pickup. Confirm the dealer accepts transfers before you order.

Frequently asked questions
- Is there a multi-pack price on the pistol?
- No. Firearms are sold one at a time and each goes through your FFL dealer; per-unit pricing applies to lowers and parts, not to the DUTY 4.0.
- What is the difference in capacity between the C and the F?
- Two rounds: 15+1 versus 17+1 with standard magazines, or 17+1 versus 19+1 with the extended base plate.
- 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.
