If a pump is what your looking for with a rifled barrel, get one with a cantilever scope mount rail. I would opt for a combo you will get more bang for your money. Dick's Sporting Goods has great deals and if you wait another month or two the deals will be better. The Mossberg 500 combo and the Remington 870 combo comes with the rifled/cantilever barrel and a 26" or 28" vent rib barrel with some chokes. The Mossberg goes for $350 now, in a month or two it will be near the $300 mark with the Remington 870 selling for about $100 more with sale or not. Both are well proven shotguns, both in your choice of 20ga. or 12ga., both are the same when it comes down to accuracy, both have great customer service, the 870 seems to be made better but that isn't true, both are made well. It comes down to personnel choice.
But if you want one of the best accurate shotguns on the market then no question the Savage 220f
