Beretta shotgun stock interchangability

[HoLeChit]

So I recently bought a beretta a300 silver mallard 12gauge from a member here. It’s a great shotgun, I really like it. I’m not a huge fan of the wood, and in my never ending quest of tinkering, I wouldn’t mind putting a different stock on it. Problem is, they don’t seem to exist. But I can find stocks for the A300 outlander, as well as the A400. Does anyone know if these interchange? Or does anyone have one that wouldn’t mind trying to swap stocks to check for fitment?
