CZ DUTY 4.0 F 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.
Full-size means 17+1 rounds, a grip that takes the whole hand and a frame 143 mm (5.6 in) high. With the extended base plate the count goes to 19+1. Empty weight is 780 g (27.7 oz), which soaks up recoil without making the gun heavy on a belt.
Where the P-10 had a registered polymer frame, the DUTY 4.0 moves the serial number to an internal modular chassis. That is the headline. The rest follows the modern service-pistol formula done carefully: a striker SFDA trigger at 25 ± 4 N (5.6 ± 0.9 lbs) (4 mm (0.16 in) reset, 9 ± 1 mm (0.4 ± 0.04 in) travel), a 188 mm (7.4 in) long slide with direct-mount optics cuts, fixed sights and a 102 mm barrel without a thread.
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 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: the belt, the nightstand and the range; the version to buy if you rarely need to hide the gun.
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.
