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.

Full-size means 17+1 rounds, a grip that takes the whole hand and a frame 143 mm (5.6 in) high. With the extended floor plate the count goes to 19+1. Empty weight is 780 g (27.7 oz), which soaks up recoil without making the gun heavy on a belt.

The standard model skips the manual thumb safety and keeps the three passive ones: firing pin block, trigger safety and trigger bar safety. Same chassis, same trigger and slide as the MS; only the lever is missing.

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

Best fit: home defense, duty use, competition and long range sessions where the extra grip and two more rounds matter. Shooters coming from a CZ 75 will recognize the grip angle; shooters coming from any other striker gun will notice the trigger first.
