CZ 1012 “Gas-Less” Hunting Shotgun

What if hunters could have a semi-automatic shotgun capable of running 5,000 rounds “without a drop of oil or cleaning of any sort” and no breakages or malfunctions? That almost sounds too good to be true, but then again, perhaps you haven’t pulled the trigger on CZ’s new 1012. Are those manufacturer’s claims all talk or will the 1012 be the most reasonably priced, gas-less repeater on the market today?
