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.

Under the DUTY name sits a registered modular chassis, a 1.3 in (33 mm) wide fiberglass-reinforced polymer frame, a 102 mm barrel and a trigger CZ rates at 25 ± 4 N (5.6 ± 0.9 lbs) with a 0.16 in (4 mm) reset. The slide is optics-ready by direct mount rather than an adapter plate. Fixed sights come standard, and the barrel is not threaded.

The F is the service-size frame: 5.6 in (143 mm) tall, 27.7 oz (780 g) unloaded, 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.

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.

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.
