Hoosiers get a straightforward deal on CZ's new striker pistol: pick the size, pick safety or no safety, name a dealer, done. The DUTY 4.0 is a 9x19mm service pistol with a fiberglass-reinforced polymer frame wrapped around a serialized modular chassis. The frame is the modular piece; the serial stays on the chassis. CZ cut the slide for direct-mount red dots and kept fixed sights, fitted a 4-inch unthreaded barrel, and tuned the SFDA trigger to a 5.6-pound pull with a 4 mm reset.

Around Indianapolis, Carmel and Greenwood, up in Hammond and Valparaiso, and east through Anderson, Muncie and Richmond, this pistol lands in two roles: a carry gun and a home-defense gun. For carry, the DUTY 4.0 C compact with 15+1 rounds and a 5.3-inch height makes sense. For the house or the range, the F full-size at 17+1 is the pick. MS versions add a manual thumb safety.

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

This is the version with a manual thumb safety. The three internal safeties (firing pin block, trigger safety, trigger bar safety) are the same as on every DUTY; the lever is an extra for people who were trained on one or simply want one.

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 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 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 reflex sights.

Best fit: daily carry, a bedside gun that also rides along, and new shooters who want one pistol for everything. Shooters coming from a CZ 75 will recognize the grip angle; shooters coming from any other striker gun will notice the trigger first.

Questions buyers ask: Can I pick up a DUTY 4.0 the same day in Indiana? Indiana has no state waiting period. Once the pistol arrives at your dealer and the background check clears, you can take it home. What is the difference between the DUTY 4.0 and the DUTY 4.0 MS? The MS adds a manual thumb safety. Both versions keep the firing pin block, trigger safety and trigger bar safety. What does MS mean on the CZ DUTY 4.0 C MS? Manual safety. It adds a thumb safety lever to the firing pin block, trigger safety and trigger bar safety that every DUTY has.
