CZ DUTY 4.0 F MS
About this product
Finishing a frame, fitting a slide and barrel, then testing the result takes a few evenings. CZ's DUTY 4.0 is the option for the evening you would rather spend shooting. It is a new-generation striker-fired 9x19mm, assembled and serialized at the factory, with the serial number on an internal chassis and a modular fiberglass-reinforced polymer grip frame around it. The 4-inch barrel is not threaded, the sights are fixed, and the slide is cut for a direct-mount red dot.
The compact C runs 15+1, or 17+1 with the extended base plate, at 770 g and 135 mm in height. The full-size F runs 17+1, or 19+1 extended, at 780 g and 143 mm. Both come in at 188 mm long and 33 mm wide. CZ's refined SFDA trigger pulls 25 N, around 5.6 lbs, with a 9 mm stroke and a 4 mm reset. Add the MS suffix for a manual thumb safety on top of the firing pin block, trigger safety and trigger bar safety. Suggested retail is $729.
Under the DUTY name sits a serial-numbered modular chassis, a 1.3 in (33 mm) 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 0.16 in (4 mm) reset. The slide is optics-ready by direct mount rather than an adapter plate. Fixed sights come standard, and the barrel is not threaded.
Capacity on the full-frame is 17+1 standard and 19+1 with the extended base plate. Height 5.6 in (143 mm), empty weight 27.7 oz (780 g). It is the duty-belt, range and home-defense version of the line, and the one most shooters find easiest to shoot well.
The MS model carries a frame-mounted manual thumb safety on top of the firing pin block, trigger safety and drawbar safety. Everything else, chassis, trigger, slide and optics cut, is the same as the version without the lever.
Who is it for: the belt, the home-defense and the range; the version to buy if you rarely need to hide the gun. If you already shoot a P-10, the DUTY is the next step in the same family, with a new chassis and the optics done right.
Because the DUTY 4.0 is a complete serialized firearm, it travels to the FFL dealer you select at checkout rather than to your address. That dealer processes the transfer paperwork and applies the rules of your state at pickup. Slides, barrels and frame kits from the rest of the store still ship direct.
