Barell options for Mossberg 500A

[GWARGHOUL]

So a while back, I got a wood furniture Mossy 500A for $125...

But it has a non-rifled smooth bore 24" slugster barel.
Great for home defense, maybe even 25 foot plinking.

But Turkey season opens Tomorrow here in MO, and is shotgun only.

I don't know much about shotguns, and Mossberg seems to be a bit elusive in thier customer care department (ordered a owners manual 4 weeks ago, and was treated very rude.. still never even got it)..

I would like some suggestions for barels (need full choke), or for the price I paid would I be better off just buying something else with screw in chokes or a full choke barel.. like an entirely different gun.. say a Weatherby pump for $300?

Thanks.

I would look for the longer vent rib barrel with screw in tubes. They are usually readily available used for decent prices. Seems everybody is wanting the shorter smooth bores for HD or just tacticool.
