The latest evolution in CZs semi-automatic shotgun line, the 1012 uses a gas-less inertia operating system. Instead of redirecting gas from the barrel to run the action, the 1012 uses a spring within the bolt to store energy during the shotguns recoil, spending this energy a split second later to rotate and unlock the twin lugs from the barrel extension and withdraw the spent shell.
- Gas-less inertia operating system
- Tuned to run a wide variety of shells
- Requires less stringent maintenance schedule than gas guns
