Ask if the store can order one for you in the model you want. If it's not an obscure manufacturer or a firearm that's made in limited quantities, then you should easily be able to order one.
Sidenote - if my LGS has the gun in stock, I'll go with them due to lower prices than national chains. However, the national chains (i.e. Cabelas) will usually accept orders over the phone, for free, while the LGS will require an in-person order with a deposit.
930 with the standoff breacher is a market gimmick, if you ask me. Breaching shotguns are usually pump-action to better deal with the special rounds.
