Which red dots fit without an adapter
The slide takes four footprints directly, using an included pin set: Trijicon RMR, Shield RMSc, Holosun K and Leupold DeltaPoint Pro. The Aimpoint ACRO and Holosun HE509T need an aftermarket adapter plate. Check that your optic fits before you order.
What is inside the frame
The DUTY is built around a patented, serialized modular chassis that holds the fire-control parts and can move between compatible grip modules. CZ lists three grip modules (small, medium, large) with different palm swell and trigger reach. Reports do not say whether every pistol ships with all three.
Safeties and controls
The pistol has drop, trigger and out-of-battery safeties. The slide release and magazine release are ambidextrous, and you can disassemble it without pulling the trigger. MS models add an external manual safety.
Durability claims
CZ guarantees a 50,000-round service life with standard ammunition, or 25,000 rounds of DM51 overpressure ammunition. These are manufacturer claims.
Magazines and holsters
The Truth About Guns reports that the DUTY accepts existing CZ P-10 magazines. The same source says CZ is working with Safariland on holsters, and no specific models are confirmed yet.
