I bought my Gen. I Saiga 12 in Idaho, took it out target shooting the same day. I have to say, it was impressive; the rate at which you can dump a full mag, and still maintain focus on a target, was comparable to a .22 rifle.
I do reccomend purchasing a couple hi-cap mags, as you will pour through ammo very quickly.
Every now and then, the gun will jam while using the "Wal-Mart Special" birdshot (never have problems using high-brass loads), minus that however, it's a flawless firearm, and I am considering buying another.
