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.

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

The chassis is registered and modular, which is CZ's way of making the frame module swappable. The frame itself is fiberglass-reinforced polymer, 1.3 in (33 mm) wide, on a 102 mm barrel and a 7.4 in (188 mm) overall length. The SFDA trigger breaks at 25 ± 4 N (5.6 ± 0.9 lbs) and resets in 0.16 in (4 mm). Optics mount directly to the slide; the photos from CZ show Holosun, Aimpoint and Shield footprints.

MS stands for manual safety. This model adds a frame-mounted lever to the automatic safeties every DUTY has: the firing pin block, the trigger safety and the trigger bar safety. Agencies and shooters who want a positive on/off control choose this version; the trigger itself is unchanged.

Who is it for: daily carry, a bedside gun that also rides along, and new shooters who want one pistol for everything. 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. 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.
