If you are a DE Resident you MUST have a DE Permit. A FL Non-resident permit is not considered a valid permit for a DE Resident. From the AG's office...
"Pursuant to 11 Del.C. ' 1441(j), as of July 11, 2003, Delaware law allows residents of other states who have been issued a concealed deadly weapon license or permit by certain other states to lawfully carry concealed deadly weapons in Delaware if the state that issued the permit or license also recognizes Delaware's concealed deadly weapons licenses, and if Delaware's Attorney General also determines that the concealed deadly weapons licensing or permit laws in the issuing state "afford a reasonably similar degree of protection as is provided by licensure in Delaware." The Attorney General has determined that only states that require proof of training in firearms safety as a part of their licensing or permit process can meet this requirement.
The Attorney General is in the process of securing agreements with the appropriate officials in certain other states which when completed, permit persons who have a concealed deadly weapon license or permit issued by one of those states to lawfully possess a concealed deadly weapon while visiting or traveling through Delaware. Similarly, Delawareans will be able to possess a concealed deadly weapon while visiting or traveling through those states. However, as of today Delaware does not recognize the concealed deadly weapon licenses or permits issued by states other than those listed below, and these states do not recognize Delaware's concealed deadly weapons licenses as valid."
