A striker-fired 9mm is not an elk gun, but nearly every Treasure Valley household that owns a rifle also wants a pistol by the door, and CZ's new DUTY 4.0 is the current answer. Boise and Nampa buyers get a 9x19 service pistol with a serialized internal chassis, a fiberglass-reinforced polymer grip frame that is modular, and a direct-mount optics-ready slide with fixed sights. The barrel is 4 inches and not threaded.

North of the valley, from Emmett and McCall up to Coeur d'Alene, Sandpoint and Bonners Ferry, and over to Salmon, people tend to size up: the DUTY 4.0 F is the full-size with 17+1 (19+1 using the extended base plate), 780 g and 143 mm tall. The DUTY 4.0 C is the compact at 15+1 (17+1 extended), 770 g and 135 mm. Both come with or without a manual thumb safety as MS models. The trigger is CZ's refined SFDA at 5.6±0.9 lbs with 9±1 mm travel and a 4 mm reset. MSRP $729.

Three things define the DUTY 4.0. First, a serialized modular chassis: the serialized part is inside, the frame module around it is modular. Second, the trigger, a striker SFDA rated at 25 ± 4 N (5.6 ± 0.9 lbs), 4 mm (0.16 in) reset, 9 ± 1 mm (0.4 ± 0.04 in) travel, which is short and repeatable for a service pistol. Third, a direct-mount optics-ready slide, shown by CZ with Holosun, Aimpoint and Shield dots fitted, so a red dot sits low without a stack of plates.

This is the shorter grip of the two DUTY frames: 135 mm (5.3 in) from the top of the slide to the base plate, 770 g (27.2 oz) empty, 15+1 rounds standard and 17+1 with the extended plate. The slide and 4-inch barrel are the same as the service-size gun, so it shoots like one.

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

Best fit: concealed carry where your state allows it, home defense, and range time that does not need a service-size grip. Shooters coming from a CZ 75 will recognize the grip angle; shooters coming from any other striker gun will notice the trigger first.

Idaho has no permit to purchase and no waiting period. Pick the Idaho dealer you want at checkout, in Boise, Coeur d'Alene or any small town in between, and the DUTY 4.0 ships to that FFL. The background check happens at your dealer's counter when you pick up. Ammo and gear ship to your door. Stock and price are verified live as part of the order, before you pay.

Questions buyers ask: Do I need a permit to buy a handgun in Idaho? No. Idaho has no permit to purchase and no waiting period; the dealer you choose runs the background check when you pick up. Which red dots fit the DUTY 4.0 slide? The slide is direct-mount optics ready. CZ's own photos show Holosun, Aimpoint and Shield red dots fitted without a plate. Does the CZ DUTY 4.0 C take CZ P-10 magazines? CZ lists the DUTY with its own 15-round magazine and an longer base plate for 17+1. P-10 magazine fit is not confirmed, so plan on DUTY magazines.
