CZ DUTY 4.0 F
Specs at a glance
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.
CZ built the DUTY around a serialized chassis that the polymer grip module wraps around, the same idea that lets a shooter change frame size without buying a new serialized gun. The trigger is a refined SFDA striker unit, 25 ± 4 N (5.6 ± 0.9 lbs) pull, 0.16 in (4 mm) 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.
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.
No manual safety here. The firing pin block, trigger safety and drawbar safety handle drop safety, and the holster handles the rest. CZ sells the same gun with a thumb safety lever as the MS model.
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.
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.
