I personally like the idea of a semi-auto turkey type shotgun for predators. I have a Mossberg semi-auto that runs good and I've killed some fox with it, but I can't recommend Mossberg as I had major struggles with their customer service to get the gun in working condition. I'll keep using it as long as it keeps working, but I won't buy another.
Personally I'd look at whatever shotgun brand you like and look at their turkey or home defense models. A bit more handy and don't really need a 28" barrel.
