[/i]Also have a question about All the other 390 series barrels
Which the " techs" at Berreta can't seem to answer
Are those barrels on the AL, silver mallards, LT ect ect ect
390 versions interchangeable with a straight 390 [/i]
Yes. A 12 gauge 390 barrel will fit any 12 gauge 390 receiver.
A 390 sporting will fit a 390 field, Silver Mallard etc. The receiver section of the 390 action is the same. I have had several 390's in different models over the years and all barrels were interchangeable.
