This is proablly been asked 100 times, but im asking again. My girlfriend likes to deer hunt and is currently using an old shotgun her dad gave her, which is an old heavy winchester bird gun. She wants a new one preferbly something I can attach a scope to, light weight, shorter than a 28in barrel for slugs. I am also going to start taking her duck hunting with me, Any recomendations for a 20ga shotgun that has interchangeable barrels for duck and deer? Pump v. Semi, etc? I was looking at a remington combo but not sure if anyone has had better luck with anything else?
