I was lucky -- I managed to grab two 5-round magazines for under $25.00 a piece before those became scarce.
Don't know if it's true or not, but I've been told that the BATF in their wisdom has made it illegal for a shotgun not manufactured in the US to have more than a 5-round magazIne. I do know that those who order the pricy ($100.00) eight round mags from Russia don't receive a magazine. Instead, they receive a kit in two shipments. Shipment one has the mag body. Shipment two has the follower and spring. It doesn't matter to me since I cannot afford to toss away a hundred dollars on a magazine.
My Saiga-12 is the one with the 22" barrel designed so the far end is a full choke. It points naturally and the gas action softens the recoil noticably as compared to a pump like the Mossberg 500 I sold in favor of the Saiga.
Yeah, I'd prefer the 19" threaded barrel, but they weren't available. Yeah, I'd like to put a high eye relief red dot sight on it. But hey, for the special price CDNN had on these last Memorial Day, there was no way to beat it. (Hard to realize I've had it nearly a full year.)
