Hinckley, 49, had sought visits as long as four days to his parents' home in Virginia from where he is being held at St. Elizabeths Hospital in Washington.
However, U.S. District Court Judge Paul Friedman did grant Hinckley from four to six additional overnight stays in the Washington metropolitan area after hearing a week of testimony about his mental condition.
Government attorneys insist Hinckley remains a potential danger and have strongly opposed even the most limited visits with his parents.
Hinckley has said he shot Reagan outside the Washington Hilton on March 30, 1981, to impress actress Jodie Foster. He also wounded White House Press Secretary James Brady, a Secret Service agent and a Washington police officer.
