Yah they went to the double slide.I did alot of research.Probably looked at 200 reviews from "pros" and consumer reviews and didn't find many bad ones.I actualy found more bad reviews on the Winchester I have been using for the past 20 years.I was a little werry of a pump shotgun that you can buy with a 28" waterfoul barrel,a 24" turkey barrel (with fiber-optic sites),a riffled cantilever slug barrel,4 chokes and a cable trigger lock all in camo for $520.00 brand new.Also found out they are the only one to pass a military spec that requires 3000 trouble free shots in various conditions including being totaly imerssed in mud without cleaning.Figured I would give the 500 a go.
Mossbergs ain't pretty or quiet but niether am I.
