Check again JG, Saiga factory mags only come in 5 & 8rd capacity, and the 8rd mags are RARE and very expensive. Your problematic 10rd mag is not factory. Most aftermarket mags will work though some need minor tweaking, and Pro-Mag mags SUCK, in ANY gun, so avoid those. Saiga shotguns need a break-in with high-brass shells to be able to reliably cycle the cheap low-brass shells. The Saiga 12 IZ109 is THE best combat/utility/defense shotgun that is currently legal in the U.S., though it is somewhat mutilated for import purposes and requires modification of at least the fire control group and the addition of a pistol grip and folding stock to restore it to it''s intended and optimal configuration. Fortunately there is a world of modification accessories for it, and even better ones are coming soon.

I own plenty of shotguns, in all calibers and barrel lengths. This is the only one that sleeps under my bed. It is just awesome. The firepower, speed and ease of operation is the best. Never had a problem with it after 400+ rounds.

awesome shot gun very mod friendly keep in mind high brass shells only target loads suck little expensive to shoot but well worth it
