I have a 590A1 loaded next to my bed, its a great shotgun, and I bought it new for around $450. I personally do not like short shottys like that, but personal preference i suppose. That would be a reasonable weapon for inside a vehicle though.
Modern semi's are so damn good. I prefer the pump, if for nothing more than superstition.
Which is odd because my #1 handgun is my 1911, and never fear it it having a FF/FF
