TRENTON, N.J. (AP) - The handgun that Shaneen Allen was carrying when she was pulled over on a New Jersey highway could have sent her to prison for years if not for a pardon from Republican Gov. Chris Christie.
  
Now the legal saga that kept the Pennsylvania mother of two in jail for 48 days has helped inspire a measure that could change handgun laws across the country.
  
The GOP-led House passed legislation this month that would allow gun owners with a state-issued concealed-carry permit to carry a handgun in any state that allows concealed weapons. The bill faces longer odds in the Senate.
  
The measure has pit gun control advocates who say that would endanger public safety against gun rights activists who say it's needed to allow gun owners to travel freely.
