First, I'm a new member to AR15.com and just saying hello to everyone:)
Here's a review of the Saiga 12, for anyone who was interested in purchasing one. Me and a friend recently purchased Saiga 12 shotguns from Izhmash. If you don't know, a saiga 12 is essentially an AK-47 rechambered for 12 gauge. They are semi-automatic shotguns that accept detachable polymer magazines. This would make reloading it faster than a tube fed shotgun. If you were thinking about buying one, then read below because I'll tell how mine was.
My first impression of the Saiga 12 was that of disgust. I thought I had wasted my money, since it was hard to rock-and-lock a loaded magazine in place, and the shotgun seemed too 'rugged'. However, I found out that the polymer magazines had really stiff springs, and performance vastly increased after use. The shotgun is very rugged, like the AK47 - I live in Alaska, and the Saiga had no jams or misfires outside in the cold, while it was snowing quite hard. This is pretty hard for a semi-auto shotgun to accomplish. In addition, the ability to send 5 slugs downrange in a little over a second is quite impressive. Lastly, you can 'color-code' magazines using colored tape or what-not, and have magazines that are strictly slugs, flechettes, buckshot, 12 gauge flash-bang or my favorite, 12 gauge fireball :) So if you're looking to buy a unique, rugged and nice-looking shotgun, the Saiga 12 should certainly be one of your considerations :)
