Columbia shooters have been asking when CZ would put out a new striker gun, and the DUTY 4.0 is it. It is a 9x19 service pistol with a serialized internal chassis, which means the fiberglass-reinforced polymer grip frame is the modular part. The slide is cut for direct-mount red dots, and CZ's own photos show Holosun, Aimpoint and Shield optics fitted, with fixed sights kept for backup. Barrel is 4 inches, not threaded; overall length 188 mm, width 33 mm.

Two sizes, two safety setups. The DUTY 4.0 C holds 15+1 (17+1 with the extended base plate) and weighs 770 g; the DUTY 4.0 F holds 17+1 (19+1 extended) at 780 g and stands 8 mm taller. Pick the MS version if you want a manual thumb safety. From Lexington and Camden out to Florence and Darlington, and down to Charleston, Summerville and Goose Creek, this is a pistol for the nightstand, the range in the Midlands and carry where South Carolina allows it. MSRP is $729.

What is new under the slide is the serial-numbered modular chassis. The serial number lives on the internal chassis, not on the polymer grip, so the polymer grip 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.

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 4-inch barrel as the carry-size, so the sight radius is identical; you buy the F for the grip and the extra rounds.

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

Who is it for: home defense, duty use, competition and long range sessions where the extra grip and two more rounds matter. 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: Do I need a permit to buy the DUTY 4.0 in South Carolina? No. South Carolina has no permit to purchase and no state waiting period; your dealer runs the background check when you pick it up. Can I put a red dot on it without a plate? Yes. The slide is direct-mount optics ready, and CZ shows Holosun, Aimpoint and Shield dots fitted. Fixed iron sights stay on as backup. Is the CZ DUTY 4.0 F MS the same gun as the F? Yes, apart from the manual thumb safety. Chassis, trigger, slide and the 17+1 capacity are identical.
