Let me add a recommendation for a much-maligned gun...
The Winchester Model 1400.
Yeah, yeah, I know... one of the "five worst guns of all time." Funny, but nobody I've talked to who owns one supports that description. I love mine.
Cheap to buy, because of the bad rap. Mine shoots everything I shove in it, no questions, no issues. I've had it so dirty on the third day of a dove hunt that I could actually watch the bolt cycle back and forth, and it never failed to eject, load, or go bang. A few extra minutes spent cleaning the gas path and it was good as new. The gun was my Dad's, then it was mine, and it never let either of us down.
Only a few minor complaints.
1. It's a bit heavy, especially after a full day spent chasing California valley quail without a dog. Autoloaders are heavy guns anyway, and #3 makes it worse in this case.
2. The trigger group should never, ever be disassembled by the owner. Ask me how I know this...
3. There's no really comfortable way to carry the gun while walking, except at port arms. There's no way to carry the gun over the shoulder (which should never be done without safety on, and knowing where everyone in your party is, shoulder-carry makes muzzle control more difficult than any other mode. It can be done safely, but constant attention is needed) without some metal edge digging in to whatever the gun is resting on. How significant a flaw this is depends on how you carry when walking afield.
Other than not being an ideal gun for afoot upland bird hunting, and no self-loader really is, I love mine. I'll never sell it.
Soft shooting, dead-nuts reliable, cheap to buy. I like 'em.
