RALEIGH, N.C. (AP) -- Gun-control advocates in the North Carolina legislature are pressing again for weapon restrictions they say will reduce the risk of mass shootings and other firearm violence.

• Several House Democrats filed omnibus gun-safety legislation on Thursday
• The measure would require background checks for all gun sales, beef up the safe-storage law and raise the age to own assault-style weapons to 21
• It would also ban high-capacity magazines and let local governments set their own gun regulations

Several House Democrats filed omnibus gun-safety legislation on Thursday, the one-year anniversary of the school shootings in Parkland, Florida, that left 17 people dead. 

The measure would require background checks for all gun sales, beef up the safe-storage law and raise the age to own assault-style weapons to 21. It would also ban high-capacity magazines and let local governments set their own gun regulations. 

First-term Democratic Rep. Christy Clark of Mecklenburg County says the bill is a first step toward addressing gun violence she calls a "public health crisis.'' Republicans leading the General Assembly have passed laws this decade actually loosening some gun laws.
