Gunfighters - View this location on map Nancy Russell, a sculptor who owns the Double Starr Studio and Gallery ( 405-282-8180) with her husband, Sheldon, says that most owners live above their shops. ''If the store is closed, just bang on the door,'' she advises. ''They'll come down and open up for you.'' In midafternoon, you may rub shoulders with men in Hollywood western regalia, heading to one of the mock gunfights staged most Saturday afternoons at 1 p.m. and 5 p.m. at Second Street and Harrison Avenue. You can hire them to shoot up your private party, too. (Guthrie Gunfighters, 405-282-6018). New York Times 328 West Oklahoma Avenue,, Guthrie, OK Shopping
