I have a Browning Gold hunter 20 that is pure magic. It is dead reliable, and hits what I want it to. You can't ask for more out of a shotgun. It is 3" capable as well. I shoot mostly 3/4 oz reloads at 1050 FPS, that is one LIGHT 20 load for a gas auto!!!! I have shot a Benelli Montefeltro 20 that is 3" capable as well. It will not cycle lighter than 7/8 oz field loads (at 1150+). It shoots very well, but felt recoil is quite a bit stiffer.
I have owned (1) 1100 and (2) 11-87s in 12 ga. I still have the 1100 and no 11-87. I would not buy a new Remington shotgun period, been there and done that. They are not what they used to be, reliability and durability are just not there. The O/U that they are marketing these days is not a deal either.
If I were in the market again I would take a long hard look at the Beretta 391 20ga, I have handled one and shot it a little. It is one FINE shotgun, but as new and did not like the light loads. It might loosen up a tad and cycle the light loads but that is unknown at this time.
