It seem's most on this site prefer the pump action over semi-auto. Why is that? Is it reliability? Today's semi-auto's have worked that out. Is it price? Is it "the sound" of racking a shell?
I too am considering a home defense shotgun, but I'm leaning towards the Mossberg 930-SPX. It has a short barrel and high capacity but could double as a SHTF gun in a pinch. What am I missing? What is the advantage of a pump over a semi-auto for home defense? I'd really like to know before I commit to a purchase.
