LTC holders across the Bay State keep asking about new striker guns, and CZ's DUTY 4.0 is the one to know about this year. It is a 9x19mm service pistol with a serialized modular chassis, a fiberglass-reinforced polymer frame and a direct-mount optics-ready slide over fixed sights. The 4-inch barrel is not threaded, overall length is 7.4 inches, and the SFDA trigger pulls at about 5.6 pounds.

CZ offers the C compact at 135 mm tall and the F full-size at 143 mm, and each comes with or without a manual thumb safety, the MS models. For buyers from Boston, Quincy and Lynn out to Worcester, Springfield and Northampton, the practical questions are roster status and configuration, and your dealer answers both before anything ships. As a new release, it is worth asking your dealer early so you are first in line if and when it is cleared.

Pick the C when the gun has to disappear under a cover garment. It gives up two rounds to the full-frame model (15+1 against 17+1) and about 8 mm of grip height, and in return it is 135 mm (5.3 in) tall and 770 g (27.2 oz) light.

No manual safety here. The firing pin block, trigger safety and trigger-bar safety handle drop safety, and the holster handles the rest. CZ sells the same gun with a thumb lever as the MS model.

Under the DUTY name sits a serialized modular chassis, a 33 mm (1.3 in) wide fiberglass-reinforced polymer frame, a four-inch barrel and a trigger CZ rates at 25 ± 4 N (5.6 ± 0.9 lbs) with a 4 mm (0.16 in) reset. The slide is optics-ready by direct mount rather than an adapter plate. Fixed sights come standard, and the barrel is not threaded.

The CZ DUTY 4.0 C suits anyone who wants a modern optics-ready 9mm with CZ's grip and a trigger that is better than the class average: daily carry, a nightstand gun that also rides along, and new buyers who want one pistol for everything.

A handgun in Massachusetts needs a License to Carry, issued by your local police licensing authority, so have your LTC before you order. Handguns transferred by a Massachusetts dealer must be on the state roster and meet the Attorney General's regulations; your dealer confirms the DUTY 4.0's status before we ship. Ammunition ships to the licensed Massachusetts dealer you pick, for pickup with your LTC or FID, while optics and most parts ship to your door.

Questions buyers ask: Is the CZ DUTY 4.0 on the Massachusetts roster? It is a new release, so ask your dealer. Handguns transferred by a Massachusetts dealer must be on the state roster and meet the Attorney General's regulations, and your dealer confirms that before we ship. Do I need an LTC or an FID for this pistol? A License to Carry. The FID card covers most rifles and shotguns; handguns in Massachusetts require the LTC, issued by your local police licensing authority. Does the CZ DUTY 4.0 C take CZ P-10 magazines? CZ lists the DUTY with its own 15-round magazine and an extended floor plate for 17+1. P-10 magazine fit is not confirmed, so plan on DUTY magazines.
