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.

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

The MS model carries a frame-mounted manual safety on top of the firing pin block, trigger safety and drawbar safety. Everything else, chassis, trigger, slide and optics cut, is the same as the version without the lever.

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.

The CZ DUTY 4.0 C MS suits anyone who wants a modern optics-ready 9mm with CZ's grip and a trigger that is better than the class average: concealed carry where your state allows it, home defense, and range time that does not need a full-size grip.

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. What does MS mean on the CZ DUTY 4.0 C MS? Manual safety. It adds a frame-mounted lever to the firing pin block, trigger safety and drawbar safety that every DUTY has.
