I just put a Winchester 1400 MKII 12 gauge on lay-a-way today. Total price out the door will be $322. It is in excellent condition. I know it's an older gun and I can't find any info out about it on Winchester's website. Does anyone know when they stopped producing these? Are they good guns? Is it worth the price I'm paying? It will be my first automatic shotgun, as the only other shotgun I've used is a 20 gauge pump action. Any thing I should be aware of with automatic shotguns?
