Browning twelvette, or Double Auto
I have 3, two dark blued and one silver..a shotgun way ahead of its time...one of the fastest to load..quick handling, light..I love em...shoot skeet and sporting clays with mine..and have taken lots of ducks.
It Can load faster that a guy with a normal semi auto..I have a spare barrel but it dosent have the piece attatched that fits into the receiver. Good spare if a barrel ever splits...Love em
