CZ DUTY 4.0 C MS

About this product

Fitment questions are most of what gets answered here, usually about which slide drops onto a PF940 frame. The CZ DUTY 4.0 raises none of them, because it arrives as a finished, factory-serialized pistol from CZ. The serial lives on an internal chassis, and the fiberglass-reinforced polymer grip frame around it is a modular part, a split frame builders will recognize.

The C compact is 135 mm tall at 770 g with 15+1 rounds, or 17+1 using the extended base plate. The F full-size is 143 mm tall at 780 g with 17+1, or 19+1 extended. Length is 188 mm and width 33 mm on both, with a 4-inch barrel that is not threaded. Sights are fixed and the slide is optics-ready for direct mounting. The refined SFDA trigger pulls around 5.6 lbs with 9 mm of travel and a 4 mm reset. MS models carry a manual thumb safety in addition to the firing pin block, trigger safety and trigger bar safety. CZ's suggested price is $729.

This is the shorter grip of the two DUTY frames: 135 mm (5.3 in) from the top of the slide to the base plate, 770 g (27.2 oz) empty, 15+1 rounds standard and 17+1 with the extended plate. The slide and 102 mm barrel are the same as the full-size gun, so it shoots like one.

CZ built the DUTY around a registered chassis that the polymer grip frame wraps around, the same idea that lets a owner change frame size without buying a new registered gun. The trigger is a refined SFDA striker unit, 25 ± 4 N (5.6 ± 0.9 lbs) pull, 4 mm (0.16 in) reset, 9 ± 1 mm (0.4 ± 0.04 in) travel. The slide takes optics by direct mounting; CZ's product photos show Holosun, Aimpoint and Shield units in place. Sights are fixed, the 102 mm barrel is not threaded.

A manual thumb safety is the one thing that separates this model from its sibling. It sits beside the three passive safeties, firing pin block, trigger safety and trigger-bar safety, and does not change the trigger pull.

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.

Since the DUTY 4.0 is a complete serialized firearm, it cannot ship to your home like a frame or jig kit. At checkout you name an FFL dealer, the pistol ships there, and the dealer completes the transfer and applies your state's rules at pickup. Confirm the dealer accepts transfers before you order.
