Make sure you check out the 28 in barrels in the Browning's also. They swing much smoother with the longer barrel and are still much shorter than a pump or an auto of the same barrel length. I had a 20ga Browning super light with 26 in barrels and was amazed at the difference in sing with the longer barrels, much better.
Nut, Cabelas is Post Falls has several o/u. I hate Cabelas but you can feel them there and then order one from a real company. Look at a Citori CX the White Eelepant in the Valley has one is stock right now. Great gun for the money, invector plus chokes 3" chamber for $1600. POI of 60/40. NorthWest Collector Pawn off of Pines had a 725 trap and a couple of nice used Winchester 101's this summer
I agree with the fit side of things. It'd be my first priority. If the stock doesn't fit you, you're not going to shoot it well. @CP and @wadu1 are very experienced in the shotguns. I'd see what they think as well. Citori's are great guns if they fit you well.
Seems like there are a lot of browning fans. I hunt mostly pheasant and sometimes quail. Anyone have expipirience with both the standard and feather weight models? Which do you prefer? Shouldering a gun in the store doesn't give me much to go off of as far as fit. Is there anywhere in the Spokane area where I could shoot a couple O/Us? I'm 6'1" and have long arms so that might become a factor in fit.
Half the shotguns on your list were Brownings and you said you wanted one of quality to pass down. Now if you want one for upland birds and are looking at price I'd whole heartedly recommend a CZ Huglu ultralight upland. I have one and really like it. Especially the 6 lb weight. I believe Browning does have an equivalent and if you want light weight and the Browning name, check that one out.
