Here is the answer from Stateline, a daily news service of the Pew Charitable Turst:
In the stunned aftermath of the Dec. 14 shooting, President Barack Obama signed 23 executive orders designed to limit gun violence. In Congress, multiple gun control measures fizzled out in the Senate without even making it to the House.
Where federal lawmakers failed to act, states debated more than 1,500 gun bills and passed 109 of them. In all of the states which made major changes to their gun laws, one party controls both the statehouse and the governor’s mansion.
