Buy It. Saiga 12's were starting to get really hard to find due to importing issues. I believe some of the import issues are fixed, but it is still a bumpy road for the shotguns future. Why wouldn't you want a clip fed AK shotgun, and they are fairly cheap in my opinion.
I do not own one, but ive shot one on multiple occasions and love it. My friend is noticing a night and day difference during his action shoots against normal semi's. Everyone on the range is now looking into them based on how he was able to perform with it. I am just now waiting for my local store to receive one and it will find its way to my gun safe.
