Turkey or Goose busters. I'd like to see a Saiga that can do even that, let alone be an effective bird swinger. No qualms here about using either of the above in a home defense situation.
Hell, I keep a 20 gauge coach gun under my bed. I figure if I can routinely shoot 50 percent on DOVES with it, a home intruder ain't got much chance. I don't need no stinkin' tacticool. that little coach gun is FAST on target. Fit and balance and light weight are probably the reasons.
Sorry - the best shotgun I have ever used is a cheapo Ted Williams from Sears and Roebuck, which I believe was a contract gun made by Winchester. I can run that pump as fast as just about any semi-automatic. It has a poly choke on the end of the barrel which makes it a perfect bird gun; when the poly choke is placed on I.C. it can throw foster slugs very accurately out to 100-125 yards. The gun is balanced quite well and can be shouldered very fast and pointed accurately. I have shot Brownings, Remingtons, Stoegers, Benellis, Mossbergs and by far my favorite is my Ted Williams.
I had one of those, but it was a "Revelation 310" with a C Lect choke, Mossberg 500 sold through Western Auto. BUT, I put a 500 barrel with a Mossberg accuchoke system on it, screw in chokes, when steel shot laws got passed. I didn't figure that adjustable choke gismo would last one round of steel shot.
Guy's gotta do what a guy's gotta do.
All in all, I'd rather own what I've got than limit myself to one gun of any kinds, let alone a Saiga. I don't, nor will I ever shoot 3 gun games. Don't need such crap for home defense. Worthless for hunting, so a Saiga would be a worthless shotgun to me. My next shotgun, in a few years, hopefully, will be a decent O/U, perhaps a Browning, but I'll have to do the shopping when I get the money. It'll probably be a 20 gauge as it'll be for doves and upland stuff, not ducks or geese. I just don't have a O/U yet and kinda want one. I goose hunt quite a bit and a Browning BPS10 would be nice, but my H&R patterns SO well, but who knows, I might get a BPS 10. I really prefer 10 to 12 for snows on the Texas coast. 10s seem to pattern better.
