North Valley shooters know CZ for the 75 and the P-10. The DUTY 4.0 is the next step: a new striker-fired 9x19mm with a serialized modular chassis, meaning the serial is on the internal unit and the fiberglass-reinforced polymer grip frame is the modular part. CZ offers four versions. The C compact carries 15+1 (17+1 with the extended base plate), stands 5.3 inches tall and weighs 27.2 ounces. The F full-size carries 17+1 (19+1 extended), stands 5.6 inches and weighs 27.5 ounces. MS models add a manual thumb safety.

From Albuquerque and Rio Rancho down to Los Lunas, up through Santa Fe and Taos to Las Vegas, and south to Truth or Consequences and Las Cruces, New Mexico buyers want one pistol that covers the nightstand, the range and concealed carry. The DUTY 4.0 has a 4-inch barrel, a direct-mount optics-ready slide with fixed sights, and a refined SFDA trigger with a 4 mm reset.

Three things define the DUTY 4.0. First, a serialized modular chassis: the serialized part is inside, the grip frame around it is modular. Second, the trigger, a striker SFDA rated at 25 ± 4 N (5.6 ± 0.9 lbs), 4 mm (0.16 in) reset, 9 ± 1 mm (0.4 ± 0.04 in) travel, which is short and repeatable for a service pistol. Third, a direct-mount optics-ready slide, shown by CZ with Holosun, Aimpoint and Shield dots fitted, so a optic sits low without a stack of plates.

Compact means 15+1 rounds in a frame 135 mm (5.3 in) high. Fit the longer base plate and it holds 17+1. At 770 g (27.2 oz) unloaded it sits between a pocket pistol and a full-frame gun, which is exactly where a carry-and-home-defense 9mm belongs.

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.

Who is it for: concealed carry where your state allows it, home defense, and range time that does not need a full-frame grip. 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.

The DUTY 4.0 ships to the New Mexico dealer you choose at checkout. New Mexico has a seven-day wait, and it is waived for concealed handgun license holders; everyone else picks up on day seven after the dealer runs the background check. Ammo and gear travel straight to your door. Stock and price are confirmed in real time as you order.

Questions buyers ask: Do I have to wait seven days for a DUTY 4.0 in New Mexico? Concealed handgun license holders are exempt from the seven-day wait. Without a license you pick up on day seven. Will my P-10 magazines work in the DUTY 4.0? CZ has not confirmed magazine compatibility with the P-10, so do not count on it. Use DUTY 4.0 magazines. What does MS mean on the CZ DUTY 4.0 C MS? Manual safety. It adds a thumb lever to the firing pin block, trigger safety and trigger-bar safety that every DUTY has.
