CZ DUTY 4.0 F MS
About this product
Frames are the rule on this site, and CZ's new DUTY 4.0 is the one complete pistol we make room for, because the question comes up constantly: what if I want the finished gun instead of the frame. This is that answer. It is a striker-fired 9x19mm, factory-assembled and factory-serialized, with the serial on an internal chassis so the fiberglass-reinforced polymer grip frame is a modular part. The slide is cut for direct-mount optics and ships with fixed sights.
Sizing follows the frame logic our customers already know. C is the compact at 15+1 rounds, 17+1 with the extended base plate, 770 g and 135 mm tall. F is the full-size at 17+1, 19+1 extended, 780 g and 143 mm tall. Both have a 4-inch unthreaded barrel and a refined SFDA trigger specified at about 5.6 lbs with a 4 mm reset. MS adds a manual thumb safety on top of the three internal safeties. Retail from CZ is $729 MSRP.
The F is the service-size frame: 5.6 in (143 mm) tall, 27.7 oz (780 g) unloaded, 17+1 rounds of 9mm on board and 19+1 with the extended floor plate. The longer grip fills a big hand and settles the gun between shots.
MS stands for manual safety. This model adds a thumb safety lever to the internal safeties every DUTY has: the firing pin block, the trigger safety and the drawbar safety. Agencies and shooters who want a positive on/off control choose this version; the trigger itself is unchanged.
The chassis is serialized and modular, which is CZ's way of making the grip module swappable. The frame itself is fiberglass-reinforced polymer, 1.3 in (33 mm) wide, on a 4-inch 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.
Best fit: the belt, the home-defense and the range; the version to buy if you rarely need to hide the gun. Shooters coming from a CZ 75 will recognize the grip angle; shooters coming from any other striker gun will notice the trigger first.
Frames go to your door; this pistol goes to your dealer. At checkout, give us the FFL who will receive the DUTY 4.0, and we ship it there. Your dealer runs the transfer and applies the rules your state sets for handgun pickups. If you do not yet have a dealer, any FFL that accepts inbound handgun transfers will work.
