The North Charleston Police Department holds its second annual gun buy back today.
North Charleston residents can turn in weapons to authorities and get gift cards in return. Those turning in a handgun or an assault weapon get a $100 card. A $50 gift card is being offered for shotguns and rifles.
Weapons must be in working order, and those turning them in must be at least 18. They must also obey the state's concealed weapons laws when bringing the weapons to two churches where they are being collected.
Last year 245 weapons were turned in during the effort.
