Maverick
I've been through several different shotguns and for GP/Home Defense I am very happy with my Maverick 88. I picked it up on a store promo for $159, then got my 10% military discount. Add on 8.8% sales tax, up to $156. NOt a bad deal.
Interchangeable with Mossberg for the most part, and rugged. Great first gun with lots of promise.
