Pistol licence holders in New York get a new CZ to consider. The DUTY 4.0 is the company's next-generation striker-fired 9x19mm, with the serial number on an internal modular chassis and a fiberglass-reinforced polymer grip frame around it. It carries a 4-inch unthreaded barrel, fixed sights and a slide cut for direct-mount red dots, and measures 7.4 inches long by 1.3 inches wide.

There are two frames, the C compact at 135 mm tall and the F full-size at 143 mm, and each is sold with or without a manual thumb safety as an MS model. For licensed shooters in Brooklyn, Queens, Yonkers and on Long Island around Hempstead and Brentwood, as well as up the Hudson in Poughkeepsie and Newburgh, this is a range and home-defense pistol with a 5.6-pound SFDA trigger and a 4 mm reset. Your dealer sets it up in the configuration New York allows.

The F is the full-size frame: 143 mm (5.6 in) tall, 780 g (27.7 oz) with an empty magazine, 17+1 rounds of 9mm on board and 19+1 with the extended base plate. The longer grip fills a big hand and settles the gun between shots.

What is new under the slide is the registered modular chassis. The serial number lives on the internal chassis, not on the polymer grip, so the frame module is a part you can change while the gun stays the same gun. Around it CZ put a reworked SFDA striker trigger, rated at 25 ± 4 N (5.6 ± 0.9 lbs) with a 4 mm (0.16 in) reset and 9 ± 1 mm (0.4 ± 0.04 in) of travel, and a slide cut for direct-mount optics. CZ's own photos show it wearing Holosun, Aimpoint and Shield optics.

A manual safety is the one thing that separates this model from its sibling. It sits beside the three internal safeties, firing pin block, trigger safety and drawbar safety, and does not change the trigger pull.

Best fit: the belt, the bedside and the range; the version to buy if you rarely need to hide the gun. Shooters coming from a CZ 75 will recognize the grip angle; shooters coming from any other striker gun will notice the trigger first.

New York requires a pistol license before a handgun can be transferred; your county licensing officer, or the NYPD License Division in the city, issues it. Every sale goes through the licensed New York dealer you name at checkout, who runs the State Police background check and applies the SAFE Act and CCIA rules before you take the pistol home. Ammunition ships to that dealer for pickup with a background check; optics and most parts ship to your door.

Questions buyers ask: Can I order the DUTY 4.0 before my pistol license is issued? The handgun cannot be transferred until you hold a New York pistol license, so get the license first; your dealer will not release it without one. What does the New York dealer do at pickup? Runs the State Police background check and applies the SAFE Act and CCIA rules, then transfers the pistol to you. 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.
