Most of what we sell goes to deer camp or the duck blind, and a 9mm service pistol has a place there too: in the truck, at camp, and at home the other eleven months. CZ's new DUTY 4.0 is a good one to pair with a hunting rifle. It is striker-fired, 9x19mm, with a fiberglass-reinforced polymer frame over a serialized modular chassis, a 4-inch unthreaded barrel and fixed sights. The slide takes a red dot by direct mount, and the SFDA trigger is rated at 5.6 pounds with a 4 mm reset.

Hunters in Tyler, San Angelo and Beaumont, in Albany and Dothan, over in Jonesboro, Hutchinson and Kearney can choose the DUTY 4.0 C compact (15+1, 27.2 ounces) or the F full-size (17+1, 27.5 ounces). Each comes with or without a manual thumb safety; the MS models add that lever to the firing pin block, trigger safety and trigger bar 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 four-inch barrel as the carry-size, so the sight radius is identical; you buy the F for the grip and the extra rounds.

The chassis is registered and modular, which is CZ's way of making the polymer grip swappable. The frame itself is fiberglass-reinforced polymer, 1.3 in (33 mm) wide, on a four-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.

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.

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.

Tell us at checkout which licensed dealer in your state should receive the DUTY 4.0, and it ships there for the background check; that dealer applies your state's handgun rules at pickup and can answer questions about them. Our state guide covers rifle seasons, not handgun purchases, so ask your dealer if you are unsure. Stock and price are re-checked against the distributor the moment you order.

Questions buyers ask: Can I use the DUTY 4.0 for deer hunting? It is a 9mm service pistol, not a hunting handgun. Check your state's handgun hunting rules; most hunters carry it as a sidearm and shoot deer with the rifle. What is the extended base plate? A magazine base that adds two rounds: 17+1 on the C and 19+1 on the F. Is the CZ DUTY 4.0 F MS the same gun as the F? Yes, apart from the manual thumb safety. Chassis, trigger, slide and the 17+1 capacity are identical.
