Duty handguns made by Česká zbrojovka (CZ) go back to the vz.27. In 1975, the CZ-75 hit the market, a groundbreaking pistol that was one of the first Wonder Nines. With the P-10, CZ entered the market for polymer-framed, striker-fired handguns in 2017. New for 2026, the company is introducing the CZ Duty, a modular design tailored for service use.

The CZ Duty is based around a new serialized modular chassis system.

According to CZ, “the CZ Duty does not replace the CZ P-10 family. It establishes a new pistol platform within the CZ lineup and gives shooters another option for personal defense, professional use and everyday carry.”

The Duty marks the first time that CZ has offered a handgun with a serialized modular chassis. Within the chassis is a newly patented firing mechanism with a refined trigger pull. It has a drop-safety system, that includes drop, trigger and out-of-battery safeties, and the gun can be disassembled without pulling the trigger. A version with a bilateral manual safety is also offered, and the pistol can be loaded or disassembled with the safety engaged. Controls, including the slide release, magazine release, and manual safety (if equipped) are present on both sides of the Duty for full ambidexterity.

The Duty is a modular system with interchangeable magazine and grip modules.

The fire-control chassis is placed inside a polymer grip module. Its ergonomics were developed with human-factors modeling, to accommodate a variety of hand sizes, provide optimal balance, and to help control recoil. An improved texturing has been applied to the module, including a finger rest above the trigger. Complete grip modules are available in small, medium, and large sizes that offer different trigger reach lengths and palm swells. The lower grip has a cut-out that interfaces with an extended and serrated portion of the magazine’s baseplate to assist in reloads.

Magazines are compatible with the P-10 and Duty baseplates and are available to retrofit P-10 magazines. Each pistol comes with two magazines—one that is flush fit and one with an extended baseplate that holds two additional rounds. Limited-capacity magazines that hold 10 rounds are also available.  

The Duty has several built-in safeties to make it drop-safe.

The 9 mm Luger-chambered Duty’s slide has extended cocking serrations on both the front and rear. Optics ready, the slide’s “Universal Mounting Interface” that allows for optics with RMR, RMSc, Holosun K and Delta Point Pro footprints to be attached directly to the slide, with adapter plates available to mount Aimpoint Acro, Colt Optics and Holosun HE509T footprints. Iron sights use a three-dot system with tritium inserts with a front post and a serrated-face U-notch rear. 

The Duty is available in two sizes. The 4.0 F MS is shown, with manual safety and extended 19-round magazine.

CZ designed the Duty to meet the needs of military and law enforcement use. The pistol has been tested to NATO requirements, including drop, water and debris-exposure testing. The Duty has a guaranteed durability rating of 50,000 rounds of standard pressure ammunition, 25,000 rounds of 30-percent over-pressure ammunition and is guaranteed to need no replacement parts for 10,000 rounds. Steel parts are given CZ’s patented nitride finish, including the cold-hammer-forged barrel.

The Duty 4.0 C has a compact grip module and a flush-fit 15-round magazine.

The Duty will be available in two basic sizes. Both use a 4-inch barrel. The 4.0 C combines this with a compact grip frame that holds a 15-round flush-fit magazine, while the 4.0 F uses a full-size grip frame that accommodates a 17-round flush-fit magazine. Both sizes are available with a manual safety, denoted by a “MS” designation added to the model number, for a total of four variants. All four models have an MSRP of $729. For more information, see the company’s website.

The Duty was designed and rigorously tested for duty use by military and law enforcement.
