Going on first duck hunt and am I supposed to take my my better semi auto or my cheaper 870 Pump action? This is a salt water trip. I have a stoeger 2000 semi auto which is my go to gun and believe is for weathered conditions. And I have a 870 pump action which is my loaner when someone needs an extra gun. I take care of all my equipment but on a boat trip there will be uncontrollable vibration.
