CBD- I have to agree with you that I have never heard of a gas assisted inertia system either, but that is what it is called, and it works. Tested mine with 29 rounds of the cheap Winchester promotional shells and other than the first 4, which I shot from the hip and limp wristed, the next 25 were form the shoulder and it worked like a dream. the only negative I have is the magazine cut-off is so stiff that loading is a pain. If it doesn't work out by 100 shots, I'll fit it.
I got curious about these <$300 turkish SA about 8 years ago and never had a problem. Now I own 4! But, I still like my Remingtons and Benellis.
