A new service pistol from CZ does not come along every year, so the DUTY 4.0 deserves a close look from Mountain State handgun buyers. It is striker-fired, chambered in 9x19mm, and built on a serialized modular chassis inside a fiberglass-reinforced polymer frame. The slide is optics-ready by direct mount, the sights are fixed, and the 4-inch barrel is plain, not threaded.

Choose between the C compact, 15+1 rounds and 770 g, and the F full-size, 17+1 and 780 g; both are 7.4 inches long and 1.3 inches wide. MS models add a manual thumb safety. From Charleston and Huntington up to Morgantown, Fairmont and Clarksburg, and across to Martinsburg and Charles Town in the Eastern Panhandle, this is a house gun, a carry gun where allowed, and a range gun in one, with a 5.6-pound SFDA trigger that rewards practice.

This is the longer grip of the two DUTY frames. It holds 17+1 rounds, 19+1 with the extended plate, stands 5.6 in (143 mm) and weighs 27.7 oz (780 g) unloaded. Same slide, same four-inch barrel as the compact, so the sight radius is identical; you buy the F for the grip and the extra rounds.

What is new under the slide is the serialized modular chassis. The serial number lives on the internal chassis, not on the polymer grip, so the grip 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 0.16 in (4 mm) 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 red dots.

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

The CZ DUTY 4.0 F suits anyone who wants a modern optics-ready 9mm with CZ's grip and a trigger that is better than the class average: the belt, the bedside and the range; the version to buy if you rarely need to hide the gun.
