No sir. From VZ'S website "The latest evolution in our 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 shotgun's recoil, spending this energy a split second later to rotate and unlock the twin lugs from the barrel extension and withdraw the spent shell. The major advantage of an inertia system is the less stringent maintenance schedule." Full details here https://cz-usa.com/product/cz-1012/

The 1012 uses a gas-less inertia operating system. So in lieu of a typical model that will redirect gas from the barrel to run the action the 1012 has a spring (housed in the bolt) to store the energy during the recoil operation, then using the energy a moment later to rotate and unlock the bolt lugs from the barrel to extract and eject the spent shell casing. Additionally the inertia system doesn't require as strict of a maintenance schedule like gas guns. During CZ's testing of the 1012 they were able to run 5000 rounds without oil and cleaning. During that test the gun performed flawlessly with zero broken parts and zero malfunctions. So during normal field use with cleaning and oiling you can rest assured that your 1012 will perform. Moreover this shotgun was tested with light recoiling 2-3/4" target loads all the way up to heavy 3" magnums and the performance was exceptional. The 1012 was able to cycle and run the vast majority of shotshells on the market with the exception of Win

Joel, no this is a gas-less inertia operating system. You can read all about it here-- https://cz-usa.com/product/cz-1012/

Joel, this model uses a gas-less inertia operating system as demonstrated here : https://www.youtube.com/watch?v=hLro9wdHq44
