I was researching the laws in anticipation of a trip.
Sorry to be a downer, but neither state (DE/SC) seems to list each other as reciprocal:
South Carolina Lists: Alaska, Arizona, Arkansas, Florida, Kansas, Kentucky, Louisiana, Michigan, Missouri, North Carolina, Ohio, Oklahoma, Texas, Tennessee, Virginia, West Virginia, and Wyoming. (

Delaware lists: ALASKA, ARIZONA, ARKANSAS, COLORADO, FLORIDA, KENTUCKY, MAINE, MICHIGAN, MISSOURI, NORTH CAROLINA, NORTH DAKOTA, OHIO, OKLAHOMA, TENNESSEE, TEXAS, UTAH, VIRGINIA, WEST VIRGINIA. (

http://www.handgunlaw.us/states/delaware.pdf , UPDATED 8/15/11, also lacks SC.
This is perhaps an illustration of the risks of using non-primary sources.
