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.

Pick the F when the gun lives on a belt or in a home-defense rather than under a T-shirt. Over the carry-size it adds two rounds (17+1 against 15+1), about 8 mm of grip and 10 g of weight, and nothing else changes.

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.

Under the DUTY name sits a serialized modular chassis, a 33 mm (1.3 in) wide fiberglass-reinforced polymer frame, a four-inch barrel and a trigger CZ rates at 25 ± 4 N (5.6 ± 0.9 lbs) with a 4 mm (0.16 in) reset. The slide is optics-ready by direct mount rather than an adapter plate. Fixed sights come standard, and the barrel is not threaded.

The CZ DUTY 4.0 F MS suits anyone who wants a modern optics-ready 9mm with CZ's grip and a trigger that is better than the class average: home defense, duty use, competition and long range sessions where the extra grip and two more rounds matter.

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. 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.
