New on the arrivals list: CZ's DUTY 4.0, the new-generation striker 9x19mm, dated and listed the day it came in. It ships in four configurations, C compact, F full-size and MS versions of each with a manual thumb safety, and every one has a direct-mount optics-ready slide, fixed sights, a 4-inch unthreaded barrel and a 1.3-inch width. The serialized component is an internal modular chassis inside a fiberglass-reinforced polymer frame.

For duty-pistol and everyday-carry buyers in Houston, San Antonio, Pensacola, Nashville, Birmingham or Columbus, the numbers matter: the F runs 17+1, 19+1 with the extended base plate, at 780 g; the C runs 15+1, 17+1 extended, at 770 g and 135 mm tall. The SFDA trigger is rated at 5.6 pounds, plus or minus 0.9, with 9 mm of travel and a 4 mm reset. CZ's launch photos show Holosun, Aimpoint and Shield dots fitted. MSRP is $729.

Where the P-10 had a registered polymer frame, the DUTY 4.0 moves the serial number to an internal modular chassis. That is the headline. The rest follows the modern service-pistol formula done carefully: a striker SFDA trigger at 25 ± 4 N (5.6 ± 0.9 lbs) (0.16 in (4 mm) reset, 9 ± 1 mm (0.4 ± 0.04 in) travel), a 7.4 in (188 mm) long slide with direct-mount optics cuts, fixed sights and a 102 mm barrel without a thread.

The C is the short-grip frame. It stands 5.3 in (135 mm) tall, weighs 27.2 oz (770 g) unloaded and carries 15+1 rounds of 9mm, or 17+1 once the extended base plate is fitted. Short enough to hide under a shirt, long enough to get every finger on the grip.

There is no manual safety on this model. Drop safety comes from the firing pin block, the trigger safety and the trigger bar safety, the way most modern striker pistols are set up. If you want a frame-mounted lever, the MS version has one.

Who is it for: concealed carry where your state allows it, home defense, and range time that does not need a service-size grip. 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.

Questions buyers ask: Which optics has CZ shown on the DUTY 4.0? CZ's photos show Holosun, Aimpoint and Shield red dots on the direct-mount slide. Confirm your optic's footprint against the cut before ordering plates or screws. Is the DUTY 4.0 a duty-size gun? The F full-size is 143 mm tall with 17+1 rounds and a 4-inch barrel, the usual duty footprint; the C compact trims 8 mm of height and two rounds for carry. Does the CZ DUTY 4.0 C take CZ P-10 magazines? CZ lists the DUTY with its own 15-round magazine and an extended base plate for 17+1. P-10 magazine fit is not confirmed, so plan on DUTY magazines.
