Hello, im in the market for a new shotgun. I would prefer a semi-auto or an over/under shotgun since I want to upgrade from my Mossberg 500 pump. I LOVE the mossberg 500. i have had it for 2 years. i have never had a problem with it, it just feels like its time to upgrade. i would like some suggestions, but what i am basically looking for is a multi-purpose shotgun. i will be hunting ducks, geese, pheasants, rabbits, coyotes, and some clays. But i am a lefty. so it would help if the shotgun has a top tang safety or an ambidextrous safety. the price range probably would be up to a grand. thank you for any input!
