CZ fans know the line-up: the CZ 75 family on the hammer side, the P-10 on the striker side. The DUTY 4.0 is the next striker gun, and it brings a new architecture. The serial number now sits on an internal modular chassis, with a fiberglass-reinforced polymer grip frame around it, and the SFDA trigger has been refined to 5.6 pounds with 9 mm of travel and a 4 mm reset. The slide is direct-mount optics-ready, the sights fixed, the 4-inch barrel unthreaded.

Four models: C compact at 15+1 and 135 mm tall, F full-size at 17+1 and 143 mm, each with an MS variant that adds a manual thumb safety. For Kansas buyers from Overland Park and Kansas City to Wichita, Salina and Great Bend, it slots in as the home-defense or carry pistol next to a Scorpion-style 9mm carbine. This is an independent CZ-focused shop, not affiliated with CZ-USA, and the DUTY 4.0 is a $729 MSRP new release.

Under the DUTY name sits a registered modular chassis, a 33 mm (1.3 in) 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 4 mm (0.16 in) reset. The slide is optics-ready by direct mount rather than an adapter plate. Fixed sights come standard, and the barrel is not threaded.

Capacity on the carry-size is 15+1, with a 17+1 option through the extended base plate. Height is 135 mm (5.3 in) and the empty weight 770 g (27.2 oz). If you carry, this is the DUTY to look at; if you mostly shoot at the range, see the F.

The MS model carries a frame-mounted manual 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.

The CZ DUTY 4.0 C MS suits anyone who wants a modern optics-ready 9mm with CZ's grip and a trigger that is better than the class average: daily carry, a bedside gun that also rides along, and new buyers who want one pistol for everything.

Pick the C, F or MS model and name the Kansas dealer you want it shipped to. Kansas has no purchase permit and no waiting period; your dealer runs the NICS check at pickup. Magazines, optics and ammo ship to your door. Live price and stock checks happen at order time, before payment.

Questions buyers ask: Do DUTY 4.0 magazines work in a P-10? CZ has not confirmed magazine compatibility with the P-10, so treat them as separate until CZ says otherwise. Buy DUTY 4.0 magazines for the DUTY 4.0. Does the DUTY 4.0 come with a manual safety? Only the MS versions have the thumb safety; the standard C and F rely on the firing pin block, trigger safety and trigger bar safety. What does MS mean on the CZ DUTY 4.0 C MS? Manual safety. It adds a frame-mounted lever to the firing pin block, trigger safety and trigger bar safety that every DUTY has.
