CZ DUTY 4.0 F MS
About this product
Builders and non-builders both shop here, and this listing is for the second group, or the first group on a day when they want a gun that is already done. CZ's DUTY 4.0 is a new striker-fired 9mm sold in four forms: the C compact, the F full-size, and MS versions of each that add a manual thumb safety. The number is on the internal chassis, so the fiberglass-reinforced polymer frame is a modular piece around it.
Compare it to a finished build and the specs hold up. A 4-inch barrel, fixed sights, 188 mm overall and 33 mm across the slide. The optics cut is direct-mount, and CZ's own images show Holosun, Aimpoint and Shield dots sitting on it. The SFDA trigger pulls about 5.6 pounds with a 4 mm reset and 9 mm of travel. Capacity is 15+1 for the C and 17+1 for the F, with extended base plates adding two rounds. MSRP for the new release is $729.
Capacity on the full-size is 17+1 standard and 19+1 with the extended floor plate. Height 143 mm (5.6 in), empty weight 780 g (27.7 oz). It is the duty-belt, range and home-defense version of the line, and the one most shooters find easiest to shoot well.
CZ built the DUTY around a registered chassis that the polymer grip frame wraps around, the same idea that lets a shooter 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 4-inch barrel is not threaded.
MS stands for external safety. This model adds a thumb safety lever to the automatic safeties every DUTY has: the firing pin block, the trigger safety and the trigger-bar safety. Agencies and shooters who want a positive on/off control choose this version; the trigger itself is unchanged.
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: home defense, duty use, competition and long range sessions where the extra grip and two more rounds matter.
Like every factory firearm on this site, the DUTY 4.0 goes to an FFL dealer rather than to your house. Name the dealer at checkout, and we ship the pistol there with tracking. The dealer runs the transfer paperwork and applies whatever your state requires at pickup. If you have not used a dealer for a transfer before, confirm they accept them before ordering.
