My friend has a Remington 870 he bought new when he was in the service in 1972. He still has it and its still his go to gun for most of his hunting, small game, waterfowl, upland and turkey. Never gave him a problem and he loves it. Remington has made over 12,000,000 of 'em since 1950. There will always be after market accessories for this shotgun. Sooner or later somebody is going to reopen Remington. I happen to use a Rem Turkey/Predator 870 right now for the last 5 years and I am very happy with it.
My vote goes to Remington 870!
