+1 on the 1300. It is a fast shotgun, probably quicker than the Remington. It's got a rotating bolt that, by design, unlocks after it fires (I don't know the technical explanation) and helps with the pump action.
I've got both an 870 and a 1300 in my battery. The 870 is my cruiser shotgun, mainly because its a standard for police work. The 1300 is my wing-shooting shotgun.
