(CNN) Before the shock and horror subside after a mass shooting, a long-simmering debate inevitably heats up over gun control.
The shooting on October 1 in Las Vegas, in which at least 58 people were killed and at least 515 were injured, will no doubt focus a spotlight on Nevada's gun laws, some of which are among the nation's least restrictive.
Authorities have not revealed the specific type of gun or guns used by the shooter, although they believe he purchased them legally.
Some facts about gun laws in the Silver State:
The Law Center to Prevent Gun Violence, a gun-control advocacy group that tracks firearms legislation, gives Nevada a grade of C- on its gun laws -- lower than more restrictive states such as California or Massachusetts but higher than 25 states that scored an F.
Studies have linked tighter gun legislation to lower rates of gun violence.
When a gun show takes place in Nevada, rates of gun deaths and injuries rise in neighboring California during the next two weeks, according to a study published Monday. But when the gun shows take place in California, this local effect is not seen -- even when accounting for California's 10-day waiting period.
According to a Pew survey conducted in March and April, 83% of American adults said they consider gun violence in the US a big problem. But far fewer, 47%, say there would be fewer mass shootings in the US if it were harder for people to legally obtain guns.
Support for stricter gun laws often spikes temporarily after mass shootings.
