CZ DUTY 4.0 F
Specs at a glance
About this product
Alongside Polymer80 frames and build kits, the complete pistols on these pages are for the buyer who wants to skip the drilling and shoot this weekend. CZ's DUTY 4.0 joins the Springfield, Rossi and Taurus handguns in that lineup as a brand-new release. It is a striker-fired 9x19mm, and its construction will interest anyone who builds: the serialized part is an internal chassis, and the fiberglass-reinforced polymer grip frame around it is modular.
The C compact holds 15+1 rounds, or 17+1 with the extended base plate, weighs 770 g and is 135 mm tall. The F full-size holds 17+1, 19+1 extended, weighs 780 g and is 143 mm tall. Both measure 188 mm in length and 33 mm in width, carry a 4-inch barrel without threading and wear fixed sights on an optics-ready slide cut for direct mounting. The refined SFDA trigger pulls 25 N, about 5.6 lbs, with 9 mm travel and a 4 mm reset. MS versions add a manual thumb safety. MSRP is $729.
This is the longer grip of the two DUTY frames. It holds 17+1 rounds, 19+1 with the extended plate, stands 5.6 in (143 mm) and weighs 27.7 oz (780 g) unloaded. Same slide, same 102 mm barrel as the carry-size, so the sight radius is identical; you buy the F for the grip and the extra rounds.
What is new under the slide is the serial-numbered modular chassis. The serial number lives on the internal chassis, not on the polymer grip, so the polymer grip is a part you can change while the gun stays the same gun. Around it CZ put a reworked SFDA striker trigger, rated at 25 ± 4 N (5.6 ± 0.9 lbs) with a 0.16 in (4 mm) reset and 9 ± 1 mm (0.4 ± 0.04 in) of travel, and a slide cut for direct-mount optics. CZ's own photos show it wearing Holosun, Aimpoint and Shield optics.
The standard model skips the manual safety and keeps the three passive ones: firing pin block, trigger safety and trigger bar safety. Same chassis, same trigger and slide as the MS; only the lever is missing.
Best fit: home defense, duty use, competition and long range sessions where the extra grip and two more rounds matter. Shooters coming from a CZ 75 will recognize the grip angle; owners coming from any other striker gun will notice the trigger first.
Frames and kits go to your door, while the DUTY 4.0 goes to the FFL dealer you name when you check out, because it is a serialized, complete firearm. The dealer handles the transfer paperwork and applies your state's rules when you collect it. Enter your dealer's information at checkout and the pistol ships to that address.
