I have a Beretta A390 Silver Mallard. It's been my bread and butter duck gun for the last 10 years. The problem I'm having is with the stock & forend. The stock split at the receiver after the first 2 years. I had it filled and kept going. Last year it resplit and the forend got a crack downit's full length. It's so bad I'm afraid it'll fall off. I clean and oil my guns religiously. I keep them in a climate controlled cabinet. I'm not sure why this is happenning, other than too many magnum shells through it in bad weather.

What I need is a synthetic replacement set. I've searched everywhere on the net to no avail. Any help you can give would be greatly appreciated.

Tried Beretta?

Those are 2 sites that come to mind off the top of my head. I haven't looked for that stock set before, but I'm sure you can find them somewhere. Could always drop Beretta a line, they might just back up their product.
