I'm not that familiar with all Beretta's models but if it's a through bolt stock like my 686 you may want to first check Ebay for a replacement stock. As of this writing there about 7 auctions for 680 series stocks listed including an adjustable one for clays, and about 20 on the Ebay stores. Most are 12 ga but keep an eye open.

You can also cal Rich Cole in ME and see what he has.

In the long run you'll have a better fitting gun.
