I own 2 Mossberg 500's (12 gage and .410) and own 1 Remington 870. They are both good shotguns. I shoot let hand and prefer the 500 over the 870 due to the controls being more ambidextrous. I don't think that you would go wrong with either one.
So are both worth the $200.00?????
2) I much prefer the Mossberg safety position. Starting with my finger off the trigger, I can remove the safety and move my finger to the trigger with one motion. With the Remington one must move their finger behind the trigger to disengage the safey, then back forward to contact the trigger.
I like the fact that the Mossy has no shell elevator in the way on loading. I don't have to hold the elevator down with my off hand on a bitchin' cold day to keep it from pinching my thumb or hanging my glove up in it. I have hunted ducks many days when my fingers were numbed by the cold. That shell elevator hurts
