I recently bought a 930 JM that has the Mesa Tac pistol grip stock and I'm interested in getting a factory(traditional) stock.
Where is the best place to get one?
You will also need a factory length return spring tube, which is not listed on Mossberg's web site. You will have to call them for that. You may be better off finding someone that want to swap you stocks and the complete internals. The cost of doing the full replacement of parts is quite expensive.
