Here is the pistol a lot of Connecticut permit holders have been waiting on: CZ's DUTY 4.0, a new-generation striker-fired 9x19mm built on a serialized modular chassis. Because the serial number lives on the internal chassis, the fiberglass-reinforced polymer grip frame around it is modular. There are four models in the line. The C compact holds 15+1 and stands 5.3 inches tall; the F full-size holds 17+1 and stands 5.6 inches. Pick either one as an MS model and you get a manual thumb safety added to the firing pin block, trigger safety and trigger bar safety.

Whether you live along the Gold Coast in Stamford and Norwalk, in New Haven or Bridgeport, or up the valley through Waterbury, Meriden, New Britain and Hartford, the use case is the same: a reliable 9mm for home defense, for the range, and for carry on a Connecticut pistol permit. The optics-ready slide with fixed sights means a red dot can go on now or later.

The chassis is serial-numbered and modular, which is CZ's way of making the grip frame swappable. The frame itself is fiberglass-reinforced polymer, 1.3 in (33 mm) wide, on a 102 mm barrel and a 7.4 in (188 mm) overall length. The SFDA trigger breaks at 25 ± 4 N (5.6 ± 0.9 lbs) and resets in 0.16 in (4 mm). Optics mount directly to the slide; the photos from CZ show Holosun, Aimpoint and Shield footprints.

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 longer base plate is fitted. Short enough to hide under a shirt, long enough to get every finger on the grip.

No external safety here. The firing pin block, trigger safety and drawbar safety handle drop safety, and the holster handles the rest. CZ sells the same gun with a thumb safety lever as the MS model.

The CZ DUTY 4.0 C suits anyone who wants a modern optics-ready 9mm with CZ's grip and a trigger that is better than the class average: daily carry, a nightstand gun that also rides along, and new buyers who want one pistol for everything.

Connecticut buyers bring their State Pistol Permit or DESPP eligibility certificate to the dealer. The DUTY 4.0 ships to the licensed Connecticut dealer you choose at checkout, and that dealer completes the transfer and applies the state's rules at pickup. Ammo and gear ship to your door where the law allows. We confirm price and availability at the moment you order, before any payment.

Questions buyers ask: What do I need to bring to my Connecticut dealer for pickup? Your State Pistol Permit or DESPP eligibility certificate. The dealer handles the rest of the transfer and tells you about anything Connecticut-specific. Is the DUTY 4.0 F too big for carry? At 7.4 inches long and 1.3 inches wide it is a standard service size. Many carry the F in a belt holster; the C is the easier choice for concealment. 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.
