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.

Full-size means 17+1 rounds, a grip that takes the whole hand and a frame 5.6 in (143 mm) high. With the longer base plate the count goes to 19+1. Empty weight is 27.7 oz (780 g), which soaks up recoil without making the gun heavy on a belt.

Where the P-10 had a registered polymer frame, the DUTY 4.0 moves the serial number to an internal modular chassis. That is the headline. The rest follows the modern service-pistol formula done carefully: a striker SFDA trigger at 25 ± 4 N (5.6 ± 0.9 lbs) (0.16 in (4 mm) reset, 9 ± 1 mm (0.4 ± 0.04 in) travel), a 7.4 in (188 mm) long slide with direct-mount optics cuts, fixed sights and a four-inch barrel without a thread.

There is no manual thumb safety on this model. Drop safety comes from the firing pin block, the trigger safety and the drawbar safety, the way most modern striker-action pistols are set up. If you want a thumb safety lever, the MS version has one.

The CZ DUTY 4.0 F 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. How many rounds does the CZ DUTY 4.0 F hold? 17+1 with the standard magazine and 19+1 with the longer base plate.
