SIG has a retail store located at the SIG SAUER Academy in Epping, NH. you might give them a call and see if they have it or could get it for you. I guess it might be a pretty good drive from Jersey, but could be a nice weekend if they have your gun.
Pro Shop: (603) 418-8100
Pro Shop Sales: Joe.Sutkus@sigsauer.com
Wait - just realized you probably can't transport the gun. Oh well call them anyway and see what they say.
