Brian, Check out Bob's little sport shop in Glassboro,NJ. It's in the southern end of the state. If you like Sterlingworths he had about ten of them last time I visited about a mounth ago. Never know what will turn up in his shop. Further south in Vineland is Butch's Gun World. He sometimes gets some interesting stuff. South of Philadelphia in Delaware,RT 13 in New Castel is Miller's Guns. He is a big Browning dealer and sometimes gets some nice SXS's. But as mentioned above the really high end dealers are in the northern part of the state. Don't bother bringing a gun with you since the Communists are in charge here and would like nothing more than to entangle you in their gun control web.
