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.

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

There is no manual thumb safety on this model. Drop safety comes from the firing pin block, the trigger safety and the trigger-bar safety, the way most modern striker pistols are set up. If you want a thumb lever, the MS version has one.

The chassis is serialized and modular, which is CZ's way of making the grip frame swappable. The frame itself is fiberglass-reinforced polymer, 33 mm (1.3 in) wide, on a four-inch 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: concealed carry where your state allows it, home defense, and range time that does not need a full-frame grip. Shooters coming from a CZ 75 will recognize the grip angle; owners coming from any other striker gun will notice the trigger first.

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. Does the CZ DUTY 4.0 C take CZ P-10 magazines? CZ lists the DUTY with its own 15-round magazine and an longer base plate for 17+1. P-10 magazine fit is not confirmed, so plan on DUTY magazines.
